Section 8: Multiple Input/Output Modules
8.1 Description
The CDRM-300 is an addressable module that functions as two individual relay control modules (two isolated sets of Form-C relay con-
tacts) and two Class B monitor modules.
Ratings for the relay contacts on the module are:
8.2 CDRM-300 Installation & Wiring
8.2.1 Setting an SLC address for a CDRM-300 Module
Each module is factory preset with an address of “00”. To set an SLC address, use a screwdriver to adjust the rotary switches on the mod-
ule to the desired address. Each module can use up to four (4) addresses. The base address selected via the rotary address switches will
be assigned to relay output #1 from 00 to 156. The module will automatically assign the next three addresses as appropriate to monitored
input #1, relay output #2, and monitored input #2.
8.2.2 Wiring a CDRM-300 Module (Form-C Relay)
