• For powering customer-supplied accessory devices such as sensors, PLC I/O, contactors, temperature probes, indicator lights, and/or other
electronic hardware
• Diagnostics include a dry DC-ok contact, a green DC-ok LED, and a red overload LED
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 fieldbus 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 setup software
Dedicated thermistor inputs (2)
Features:
• Each module capable of monitoring up to six thermistors in 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
