Section 8: Relay Module
8.1 Description
The M300RJ module is an addressable module that provides two isolated sets of Form-C relay
contacts.
Ratings for the dry relay contacts on a Form-C module are:
•
Resistive – 2 amps @ 30 VDC (e.g. Electronic devices and strobes)
•
Inductive – 1 amp @ 30 VDC (0.6pF) (e.g. Mechanical bells and horns)
•
Pilot Duty – 0.5 amp @ 125 VAC (0.35pF) (e.g. Using a smaller relay to trip another relay)
For more information on the module specifications refer to the
Installation Instructions
provided
with this device. For information on transponders, refer to the specific transponder manual.
Setting an SLC Address
Each relay module is factory preset with an address of “00.” To set an SLC address refer to
Section 6.2, “Setting an SLC Address for a Module”, on page 35.
