Given the following digital output module show how you would

Given the following digital output module, show how you would connect to it a Indicator light Relay/contactor

Solution

(a)

All terminals with the same name are connected together on the module. For example, DC COM can be connected to either terminal marked GND-1. Do not physically connect more than two wires to a single RTB terminal. When you daisy chain from a group to another RTB, always connect the daisy chain.

indicator light is always connected to the DC output terminal for the digital output terminal.

(b)

The 1756-OB16D card has an internal resettable electronic fuse. relays are generally connected to terminals number 13 and 14. connect + terminal to pin 14 and - terminal to pin 13.
