Relay Output Contact Modules
There are four ‘Form C’ 5 Amp relay contacts in each Model RL4 module. These can be used to fire
annunciating devices or as signal inputs to other control devices. Connect to the relay contacts of the Model
RL4 module as shown
Figure 11. Note that the Amp rating of the relay contact should not be exceeded.

4-20mA Output Modules
There are four 4-20mA outputs in each Model AO-4 module. These can be used as signal inputs to other
control devices. Connect to the AO-4 modules as shown in Figure 12:

Contact Input Modules
There are four addressable contact inputs in each DI-4 Module. The Module is powered by 24VDC, and the
voltage is used to produce a 4mA level when the contacts are open and a 20mA level when the contacts are
closed.
