I/O Modules

Specifications

Power Supply: DC24V

PCB Dimension: 103*71.6 (mm)

Input Signal: 0-10V

Input Signal for Indicators: On/Off

Relays: SPDT 4PCS

Output: 20mA 24V

Functions:

The controller has four indicators for input signals, and when short circuit between S1/S2/S3/S4 and terminal block marked with 24V happens, the LEDs will be lit accordingly and the color of LED can be changed via the jumpers.

The controller has four relay outputs and each circuit has a switch to control its output and also
indicates the position status of the switch (ON COM AUTO):

When the switch is switched at ON position, the relay will have an output with COM and ON
connected;
When the switch is switched at OFF position, the relay will stop working and there’s no output;

When the switch is switched at AUTO position, the relay will work according to the 0-10V input and COM and AUTO will be connected.
