Step 5b: (Optional) Connect the RS-232 Host interface 

As discussed in 5a this step is necessary if the controller is to be linked to the Host using the RS-
232. This step is unnecessary if the controller uses the RS-485 to another controller that is linked 
to the host or if the Ethernet interface is being used.

Step 6: Connecting the digital inputs 

Before wiring the digital inputs make sure that the power is switched off on the controller board. 
When looking at the controller board with the power connector on the top right of the board, the 
inputs are arranged in ascending order from left to right with a shared common between each 
input pair. See the diagram below on how to correctly wire them.

Step 7: Connecting the digital outputs 

Before wiring the digital inputs make sure that the power is switched off on the controller board. 
When looking at the controller board with the power connector to the right, the outputs are 
arranged in ascending order from left to right. 

 

 

The outputs can provide 12Vdc power, or simply act as a potential free contact, allowing external 
DC or AC power to be switched through the relay.  
 
The configuration of this output mode can be accomplished using the jumpers J11 to J15. 
Possible output modes are listed below.
