SKU CH-Q1QY-X1DYY

Monitors rotational speed on one intrinsically safe channel from 0.06 to 600000 min with two relay and one transistor output

  • Intrinsically safe input suits Zone 2 hazardous areas
  • Single channel monitors speeds from 0.06 to 600000 min
  • Two relay outputs plus one transistor output provide switching flexibility
  • Compact IM21 housing fits tight control cabinets
  • Manufacturer part 7505651 ensures exact replacement identification

Rotation Speed Monitor with Intrinsically Safe Input

The Turck IM21-14EX-CDTRI is a single-channel rotation speed monitor designed for industrial machinery oversight. It accepts an intrinsically safe input suitable for Zone 2 hazardous areas. The unit covers a measurement range from 0.06 to 600000 min. Two relay outputs and one transistor output provide switching and signalling capabilities.

Suited for Hazardous Area Speed Monitoring

This device suits engineers monitoring rotational velocity in environments requiring intrinsic safety barriers. It is not for applications needing multiple independent sensor channels or analogue current outputs. Buyers who require a safe-area-only instrument without Zone 2 certification should look at alternative monitoring relays.

Measurement Range 0.06 to 600000 Min

The defining specification is the speed range of 0.06 to 600000 min, which determines whether the monitor matches the machine's operating envelope. Verify that the target equipment's minimum and maximum speeds fall within these limits before specifying the part. The single-channel architecture processes one sensor signal only.

Questions about this item

Does the IM21-14EX-CDTRI fit a standard DIN rail mounting?

The IM21-14EX-CDTRI is a module designed for control cabinet installation; check the housing datasheet for the exact rail type.

How do I wire the intrinsically safe input on the IM21-14EX-CDTRI?

Connect the sensor to the intrinsically safe input terminals respecting the 0.06-600000 min⁻¹ range; the common error is reversing the barrier polarity.

What maintenance does the IM21-14EX-CDTRI require over time?

No user-serviceable parts inside; schedule periodic verification of the relay and transistor outputs against a calibrated reference.
