2) there is no vibrations or impact

3) there are no corrosive gases (sulphuric gas,

ammonia, etc.).

4) there are no water or other fluid (i.e. condense)

5) the ambient temperature is in accordance

MEASURING INPUTS

NOTE: Any external component (like zener

barriers etc.) connected between sensor and

input terminals may cause errors in

measurement due to excessive and/or not

balanced line resistance or possible leakage

currents.

TC INPUT

Fig. 4 THERMOCOUPLE INPUT WIRING

NOTE:

1) Don’t run input wires together with power

cables.

2) For TC wiring use proper compensating cable

preferable shielded.

3) When a shielded cable is used, it should be

connected at one point only.

RTD INPUT

Fig. 5 RTD INPUT WIRING

NOTE:

1) Don’t run input wires together with power

cables.

2) Pay attention to the line resistance; a high

line resistance (higher than 20 Ω/wire) may

cause measurement errors.

3) If shielded cable is used, it should be

grounded at one point only.

4) The resistance of the 3 wires must be the

same.

LINEAR INPUT

Fig. 6.A mA INPUT WIRING

Fig. 6.B 60mV INPUT WIRING

NOTE:

1) Don’t run input wires together with power

cables.

2) When shielded cable is used, it should be

grounded at one side only to avoid ground

loop currents.

3) For mV input, pay attention to the line

resistance; a high line resistance may cause

measurement errors.

4) The input impedance is equal to:

< 5 Ωfor 20 mA input.

> 1 MΩfor 60 mV input.

LOGIC INPUT

Safety note:

1) Do not run logic input wiring together with

power cables.

2) Use an external dry contact capable of

switching 5 mA, 7.5 V DC.

3) The instrument needs 100 ms to recognize a

contact status variation.

4) The logic inputs is isolated by the measuring

input.

Fig. 7 - LOGIC INPUT WIRING

This logic input can be programmed in order to

perform the following functions:

a) to switch from main set point to auxiliary set

point and viceversa.

logic input op. set point

open main SP

close auxiliary SP (SP2)

b) to hold the set point ramp execution.

CURRENT TRANSFORMER INPUT

Fig. 8 CURRENT TRANSFORMER INPUT

WIRING

Note:

1) The input impedance is equal to 12 Ω.

2) The maximum input current is equal to 50 mA

rms (50 / 60 Hz).

RELAY OUTPUTS

Fig. 9 RELAY OUTPUTS WIRING

The contact rating of the OUT 1, 2 and 3 is

3A/250V AC on resistive load.

The number of operations is 3 x 105at specified

rating.

NOTES

1) To avoid electrical shock, connect power line

at the end of the wiring procedure.

2) For power connections use No 16 AWG or

larger wires rated for at last 75 °C.

3) Use copper conductors only.

4) Don’t run input wires together with power

cables.

All relay contacts are protected by varistor

against inductive load with inductive component

up to 0.5 A.

The following recommendations avoid serious

problems which may occur, when using relay

output for driving inductive loads.

INDUCTIVE LOADS

High voltage transients may occur switching

inductive loads.

Through the internal contacts these transients

may introduce disturbances which can affect the

performance of the instrument.

For all the outputs, the internal protection

(varistor) assures a correct protection up to 0.5

A of inductive component.

The same problem may occur when a switch is

used in series with the internal contacts as

shown in Fig. 10.

Fig. 10 EXTERNAL SWITCH IN SERIES WITH

THE INTERNAL CONTACT

In this case it is recommended to install an

additional RC network across the external

contact as show in Fig. 10

The value of capacitor (C) and resistor (R) are

shown in the following table.

The cable involved in relay output wiring must be

as far away as possible from input or

communication cables.

VOLTAGE OUTPUTS FOR SSR DRIVE

Fig. 11 SSR DRIVE OUTPUT WIRING

It is a time proportioning output.

Logic level 0: Vout < 0.5 V DC.

Logic level 1:

- 14 V + 20 % @ 20 mA

- 24 V + 20 % @ 1 mA.

Maximum current = 20 mA.

NOTE: This output is not isolated. A double or

reinforced isolation between instrument output

and power supply must be assured by the

external solid state relay.

SERIAL INTERFACE

RS-485 interface allows you to connect slave

devices with one remote master unit.

Fig. 12 - RS-485 WIRING

NOTES:

1) The RFS is equipped with an RS-485 driver

with an input impedance fore time higher than

a standard one. For this reason it is possible

to connect 120 RFS units to the same master

(instead of 30).

1) The cable length must not exceed 1.5 km at

19200 BAUD.

2) This serial interface is isolated.

3) The following report describes the signal

sense of the voltage appearing across the

interconnection cable as defined by EIA for

RS-485.

a) The ” A ” terminal of the generator shall

be negative with respect to the ” B ”

terminal for a binary 1 (MARK or OFF)

state.

b) The ” A ” terminal of the generator shall

be positive with respect to the ” B ”

terminal for a binary 0 (SPACE or ON).

4) The EIA standard establishes that by RS-485

interface it is possible to connect up to 30

devices with one remote master unit.

The serial interface of these instruments is

based on “High input impedance”

transceivers; this solution allows you to

connect up to 120 devices (based on the

same transceiver type) with one remote

master unit.

POWER LINE WIRING

Fig. 13 POWER LINE WIRING

NOTES:

1) Before connecting the instrument to the

power line, make sure that line voltage

corresponds to the description on the

identification label.

2) Use copper conductors only.

3) Don’t run input wires together with power

cables.

4) The power supply input is NOT fuse

protected.

Please, provide it externally.

For one unit only, the fuse must be rated as

follows:

Power supply Type Current Voltage

24 V AC/DC T 315mA 250 V

When fuse is damaged, it is advisable to

verify the power supply circuit, so that it is

necessary to send back the instrument to

your supplier.

5) The maximum power consumption is equal to

6 VA (4 W) maximum.

ACCESSORIES

BUS cable

It is possible to use a screw connector instead of

the flat cable, allowing the normal wiring of a

single controller.

This flat cable allows the simultaneous

connection of the power supply, the serial

interface, the common alarm output (out 4) and

the common logic input of up to 12 instruments

plus one Common I/O unit or up to 13

instruments.

NOTE:

1) the logic inputs of each instrument can be

driven:

by its own connector (terminals 6 and 7),

without affecting the working of the other

elements

by the common logic input (terminals 24 and

25) present on the common I/O unit. In this

case, all instruments connected with the

BUS cable will detect the same logic input

condition.

2) The local logic input (terminals 6 and 7), and

the common logic input (terminals 24 and

25), are in OR condition.

COMMON I/O UNIT

This unit can perform 3 different functions:

1) It is the relay output of all the common alarm

connected by the BUS cable.

2) It performs the connection of the common

logic input of all the units connected by the

BUS cable.

3) It is the natural connection of the power

supply and of the serial link for all the units

connected by the BUS cable.

For serial interface and power supply connection

see fig. 12 and 13 and relative notes.

Common logic input

Safety note:

1) Do not run logic input wiring together with

power cables.

2) Use an external dry contact capable of

switching 100 mA, 7.5 V DC minimum.

3) The instrument needs 100 ms to recognize a

contact status variation.

4) The logic input is isolated by the measuring

input.

NOTE: As shown in Fig 18, the logic input of a

group of RFS can be driven singularly (using

terminals 6 and 7 of the specific instrument) or

collectively (using terminals 24 and 25 of the

Common I/O unit).

This logic input can be programmed in order to

perform the following functions:

a) to switch from main set point to auxiliary set

point and viceversa.
