Description

The Nelson CM-1 Circuit Monitor is a scanning microprocessor system which sequentially monitors and displays each circuit number and the status of each circuit.

The CM-1 is environmentally hardened and requires no protected operative environment. It can be located in a control room or out in a plant. The low voltage, the optically isolated design allows the unit to be installed in Division 2 Hazardous Locations.

This heater cable monitoring system continuously monitors the status of both series and parallel styles of electric heat tracing cables and panels. This system monitors the supply voltage and current flow to each heating device. With the addition of continuous monitoring devices, this system monitors both bus wires in parallel styles of heating cable.

When used in conjunction with ground fault branch breakers, the CM-1 serves as an automatic alarm system for any ground fault condition.
