Wiring Inputs and
Outputs
Figure 8 shows how to connect ARM-1 relay modules to the RM-4 outputs and how to
wire NO (Normally Open) and NC (Normally Closed) supervised inputs.
FIGURE 8. RM-4 Input/Output Connections
NOTE Maximum distance from P5 to the ARM-1 is 25 feet.
Maximum distance from P5 to the inputs is 2000 feet.
Locate the 1KΩ resistors for the NO and NC supervised inputs as close as possible
to the switch.
To comply with UL requirements, use shielded, minimum 22 AWG stranded,
twisted pair cable for monitor points, DSMs, and REXs. Use Belden 9462 or
equivalent.
