External Temperature Monitoring
Designed for monitoring temperatures of external system components, such as the motor windings and/or bearings. Includes eight universal input modules
plus two dedicated thermistor input modules. All ten modules are integrated into the drive’s safe stop circuit and can be monitored via a serial commu-
nication bus network (requires the purchase of a separate module/bus coupler).
Universal inputs (8)
Signal types:
•
RTD inputs (including Pt100), 3-wire or 4-wire
•
Thermocouple
•
Analog current or analog voltage
Additional features:
•
One universal output, configurable for analog voltage or analog current
•
Two output relays (N.O.)
•
Dual-line LC display and LED diagnostics
•
Sensor lead wire break, short-circuit, and incorrect polarity detection
•
Interface set-up software
Dedicated thermistor inputs (2)
Features:
•
Each module is capable of monitoring up to six thermistors in a series
•
Fault diagnostics for wire breakage or short-circuits of sensor leads
•
ATEX/UL/CSA certification
•
A third thermistor input can be provided by the PTC thermistor option card MCB 112, if necessary.
