Connections
(1) The isolators adopt knock-down terminals.
(2) The wires are single or multiple cables with cross-section of 0.5
2 2.
mm ~2.5mm
(3) A length of 8mm bared wire is locked by the M3 bolt. As shown in
figure.
Installation
Mount the module on a 35mm DIN rail
(1) Make the upside of the isolator to the rail;
(2) Push the downside of the isolator towards the rail.
Disassembly
(1) Use a screwdriver (edge length≤6mm）insert the metal lock which
at the downside of the isolator;
(2) Push the screwdriver upwards, and pull the metal lock downwards;
(3) Take out the isolator from the rail.
Maintenance
(1) Every product has been tested strictly before delivery. If users
find any abnormality, please contact the nearest agent or our
company.
(2) In 5 years from delivery date, if the product performs abnormally
under normal use conditions, we will repair it for free.

Digital signal input Isolator, receive the switch or proximity switch
signal from the filed to control room through the isolator .This device
has selectable line fault detect (LFD) indicating function and each
channel of it can be setting output & input in-phase or reverse phase
control mode.It need independent power supply.The power part,the
input part and the output part are isolated from each other.
Number of channels: 2
Supply voltage: 20~35V DC
Current consumption: (at 24V DC,output energized)≤60mA
Input:
Input signal: switch, proximity detector
Open circuit voltage: ≈8V
Short circuit current: ≈ 8mA
Output:
Response time: ≤10ms
Drive ability: 250V AC,2A or 30V DC,2A
Load type: resistive load
Input/Output Characteristics:
Switch closed/Input loop-current＞2.1mA,output relay is energized
yellow LED ON.
Switch open/Input loop-current＜1.2mA,output relay is de-energized
yellow LED OFF.
Function of the switch setting:
Note: Switch K2、K4 must be set to OFF state, no line fault (brea-
kage, short circuit) detection; When using line fault (breakage, short
circuit) detection function, resistors must be fitted, 22kΩ in parallel with
switch, 680Ω in series with switch, see Switch (II), K2 、K4 set to ON
state.
Power supply protection:
Protect the product from reverse supply voltge destroy
Electromagnetic compatibility: According to IEC 61326-1(GB/T 18268)
Dielectric strength:
1500V AC;1minute(among power supply ,input and output )
Insulation resistance:
≥100MΩ;500V DC(among power supply,input,output and the shell)
Weight: Approx.150g
Suitable IS apparatus:
Compliance with DIN19234 of NAMUR proximity switches,switches
and other field equipment (including:intrinsically safe pressure
switches, temperature switches,level switches,etc.)
