DIP Switches: Used for node addressing and configuration
selections.
Output Status: LEDs indicate the ON/OFF status of each out-
put.
Input Status: LEDs indicate the ON/OFF status of each input.
Inputs: Four digital inputs available. Must be purchased as 24
Vdc or 120 Vac.
Test/Reset: Used to manually trip the base control module.
Also used to reset the module after a trip has occurred.
USB Port: Micro AB connector. Enables configuration upload.
Status LEDs:
Status: Indicates the trip status of the base control module.
•
CH1: Indicates status of modules attached to Channel 1 port
•
on Base Control Module (measurement module or user inter-
face).
CH2: Indicates status of modules attached to Channel 2 port
•
on Base Control Module (measurement module or user inter-
face).
USB: USB traffic indication.
•
Real Time Clock and Memory Backup Module: Optional real
time clock module. Plugs in behind the communication cards.
Provides battery backed-up fault time stamping and non-volatile
memory for configuration parameters.
Communication Modules: Optional modules to provide com-
munications.

Relay Outputs 1 & 2: Two normally open outputs.
Relay Output 3: Form C NC/NO. Factory orderable as latching
or non-latching. Two options available: 120–240 Vac or 24 Vdc
RS-485: Modbus Serial terminal (factory orderable option only)
CH1 Port: Provides connection and power from the base con-
trol module to the connected module (measurement module or
user interface)
CH2 Port: Provides connection and power from the base con-
trol module to the connected module (measurement module or
user interface)
Measurement Module Basic Overview
The measurement module is a pass-through device which sam-
ples current and voltage data consumed by the system. This
data is continually transmitted back to the base control module
for analysis. Various frame sizes are available for applications up
to 800 A, with factory orderable options for voltage measure-
ment and positive temperature coefficient (PTC) protection.
