Appendix C: Relay Module (RLY)
The RLY is a non-intrinsically safe module that has 8 identical Form C output
channels. Each channel has a fuse and three terminals. Each channel can
be configured as NO or NC with the power off by wiring to the appropriate
terminals. A T5 series console can accommodate up to 24 outputs (8 outputs
on up to 3 modules) as space allows. The diagrams below illustrate two
examples of positive shutdown upon alarm conditions.
Note: A valid dispenser hook signal coming from the AC Input Module (shown in Figure D-1) is required for the above
diagram to function as shown.

Note: The relay will need to be configured as polarity inverted in order to function correctly in the above diagram.
Note: If a dispenser’s current rating is between 2 and 10 amps, use a 10 amp relay module. If the current rating is higher
than 10 Amps, use an appropriate isolation relay.
