HEAT TRACE SYSTEMS CM-2001 SINGLE POINT CONTROL/MONITORING SYSTEM
For stand alone or networked heat tracing applications, the CM-2001 is Nelson’s most versatile
control and monitoring system. is microprocessor based controller allows operational personnel
to control the line temperature, as well as monitor various conditions such as voltage and current
alarms, ground fault leakage and trip conditions, and sensor and communication failures. e
CM-2001 is housed in a NEMA 4X enclosure that is certi ed for ordinary, Division and Zone
locations. Simple integration into existing systems is assured with the ability to connect 32
individual systems per node and compatibility to Nelson’s CM.COMM software or any Modbus
compatible device.
• User selectable control modes
• Easy to read display for quick and clear communications
• Dual RTD inputs with user selectable operations
• Programmable auto test feature
• For use in hazardous and ordinary locations

HEAT TRACE SYSTEMS CM-332 MULTI-POINT CONTROL/MONITORING SYSTEM
One of the most advanced control and monitoring systems available, the CM-332 is a
microprocessor based control and monitoring system based on standard industrial automation
products speci cally integrated for use with electric heat tracing systems. Nelson’s CM-332 system
provides temperature and current monitoring for each heat tracing circuit while communicating
additional information to operations personnel such as temperature alarms, circuit faults, and
sensor failure and communications failures.
