Mounting

Note

▪Mount on a standard DIN-rail.

▪Ensure that there is sufficient room on the sides of the device to allow for any I/O or COM

modules.

1. Push the device onto the DIN-rail until the

clips located at the top and bottom of the

unit have snapped onto the DIN-rail.

2. When properly mounted, the device is

squarely situated on the DIN-rail as shown

below.

Battery: Back-up, First Use, Installation, and Replacement

Back-up

In order to preserve back-up values for RTC and

system data in the event of power off, the battery

must be connected.

First Use

The battery is protected by the PLC’s bottom and

inner door.

The battery is supplied installed inside the unit, with

a plastic tab preventing contact.

Pull out this tab before using the device.

Battery Installation and Replacement

▪Use proper precautions to prevent Electro-Static Discharge (ESD) while servicing the battery.

Caution

▪To preserve back-up values for RTC and system data during battery replacement, the

controller must be powered.

▪Note that disconnecting the battery halts the preservation of back-up values and causes them

to be deleted.

1. Open the bottom and inner doors.

2 If there is a battery present, remove it.

3. Slide the battery into place.

UniStream®PLC

Unitronics

microSD Card Installation and Removal

▪Use proper precautions to prevent Electro-Static Discharge (ESD) while servicing the microSD

card.

1. To install the microSD card slide it into the slot

as shown in the accompanying figure, until the

card clicks into place.

2. To remove the card, press it into its slot lightly,

the spring ejects it.

Wiring

▪This equipment is designed to operate only at SELV/PELV/Class 2/Limited Power environments.

▪All power supplies in the system must include double insulation. Power supply outputs must be

rated as SELV/PELV/Class 2/Limited Power.

▪Do not connect either the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to device’s 0V point.

▪Do not touch live wires.

▪All wiring activities should be performed while power is OFF.

▪Use over-current protection, such as a fuse or circuit breaker, to avoid excessive currents into the

power supply connection point.

▪Unused points should not be connected (unless otherwise specified). Ignoring this directive may

damage the device.

▪Double-check all wiring before turning on the power supply.

Caution

▪To avoid damaging the wire, use a maximum torque of 0.5 N·m (4.4 in-lb).

▪Do not use tin, solder, or any substance on stripped wire that might cause the wire strand to

break.

▪Install at maximum distance from high-voltage cables and power equipment.

Wiring Procedure

Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm2–3.31 mm2 )

1. Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).

2. Unscrew the terminal to its widest position before inserting a wire.

3. Insert the wire completely into the terminal to ensure a proper connection.

4. Tighten enough to keep the wire from pulling free.

Wiring Guidelines

In order to ensure that the device will operate properly and to avoid electromagnetic interference:

▪Use a metal cabinet. Make sure the cabinet and its doors are properly earthed.

▪Use wires that are properly sized for the load.

▪Use shielded twisted pair cables for wiring High Speed and Analog I/O signals.

Use shielded cables for wiring thermocouple and RTD signals.

In either case, do not use the cable shield as a signal common / return path.

▪Route each I/O signal with its own dedicated common wire. Connect common wires at their

respective common (CM) points at the controller.

User Guide

Unitronics

▪Individually connect each 0V point and each common (CM) point in the system to the power supply

0V terminal, unless otherwise specified.

▪Individually connect each functional ground point ( ) to the earth of the system (preferably to the

metal cabinet chassis).

Use the shortest and thickest wires possible: less than 1m (3.3’) in length, minimum thickness 14

AWG (2 mm2).

▪Connect the power supply 0V to the earth of the system.

▪Earthing the cables' shield:

➢Connect the cable shield to the earth of the system (preferably to the metal cabinet chassis). Note

that the shield must be connected only at one end of the cable; it is recommended to earth the

shield at the PLC-side.

➢Keep shield connections as short as possible.

➢Ensure shield continuity when extending shielded cables.

NOTE

For detailed information, refer to the document System Wiring Guidelines,

located in the Technical Library in the Unitronics’ website.

Wiring the Power Supply

The controller requires an external power supply.

▪In the event of voltage fluctuations or non-conformity to voltage

power supply specifications, connect the device to a regulated

power supply.

Connect the +V and 0V

terminals as shown in the

accompanying figure.

Connecting Ports

▪Ethernet

CAT-5e shielded cable with RJ45 connector

▪USB Device

Use a standard USB cable, Type mini-B

▪USB Host

Standard USB Type-A plug

UniStream®PLC

Unitronics

Note that below, the letters “xx” that is used in the model numbers means that the section refers both to

B5/C5 and B10/C10 models.

I/O Connection Points

The IOs for these models are arranged in three

groups of fifteen points each, as shown in the figure

to the right.

Top groups

Input connection points

Bottom group

Output connection points

The function of certain I/Os may be adapted via

wiring and software settings.

Wiring the Digital Inputs

The digital inputs are arranged in two isolated groups:

▪I0-I8 share common CM0

▪I9-I12 share common CM2

Each group may be wired together as sink or source.

Inputs I9, I10, I11 and I12 can be configured as either normal digital inputs or as high speed inputs that

can receive high speed pulse signals from sensors or shaft encoders.

High Speed Input Modes

Following are the different pin assignments for the high speed

channels:
