Product Description

The Turck IM21-14-CDTRI is an industrial rotation speed monitor designed to detect overspeed, underspeed, or stoppage in rotating machinery. It delivers reliable evaluation of inductive sensor pulses and provides fast output switching to protect motors, conveyors, pumps, and mechanical drives. With high noise immunity and robust housing, the IM21-14-CDTRI ensures stable performance in harsh industrial environments.

Standard Features

  • Accurate Speed Monitoring: Detects overspeed, underspeed, and standstill conditions in rotating equipment.

  • Pulse Evaluation: Processes pulse inputs from inductive or PNP-type sensors.

  • Fast Switching Response: Millisecond-level reaction time for critical protection tasks.

  • Wide Voltage Compatibility: Accepts both AC and DC supply ranges for flexible installation.

  • Relay Output: Capable of directly interfacing with alarms, motor control circuits, and safety relays.

  • High EMC Immunity: Designed for stable performance in electrically noisy industrial environments.

  • DIN-Rail Mounting: Easy integration into control cabinets and automation panels.
