Compact octal-base time delay relay with 11 flat pins and potentiometer adjustment

Macromatic

Macromatic TR-51628-14 Off Delay Time Delay Relay

SKU CH-2X67-497YY

Off-delay time-delay relay with octal plug-in base, DPDT contacts rated 10 A at 240 V AC or 30 V DC, and adjustable range from 9 sec to 15 min

  • Off-delay timing prevents premature load shutdown
  • Potentiometer adjusts delay from 9 sec to 15 min
  • DPDT contacts switch 10 A at 240 V AC or 30 V DC
  • 11-pin octal plug-in base enables quick socket mounting
  • IP20 enclosed housing protects internal components

Single-Function Off-Delay Relay

The Macromatic TR-51628-14 is a single-function time delay relay designed for control circuits that require an off-delay action. It mounts via an 11-pin octal plug-in base for quick installation in panels or machinery. The unit accepts a 24V AC/DC coil voltage and provides DPDT contacts rated at 10 A for both 240V AC and 30V DC loads.

Suited for Simple Timing Needs

This relay suits engineers and maintenance teams needing a single, adjustable off-delay function with a range of 9 seconds to 15 minutes. The potentiometer adjustment method allows straightforward setting changes without external tools. Buyers who require multiple timing functions, on-delay or interval modes, or a different coil voltage should look at other models.

24V AC/DC Coil Voltage Determines Fit

The defining specification is the 24V AC/DC coil voltage, which must match the control circuit supply exactly. An incorrect voltage will prevent operation or damage the relay. Verify the panel supply before purchase, as this unit does not support other control voltages.

Questions about this item

How often will the potentiometer on the TR-51628-14 need recalibration or replacement?

The potentiometer is a sealed adjustment inside the enclosed relay body and has no published service interval; it is not a user-replaceable part.

What limits continuous operation of the DPDT contacts rated at 10 A @ 240 V AC?

Sustained load at the full 10 ampere rating is limited by contact heating and the IP20 enclosure's ability to dissipate that heat.

How much heat does the relay produce when powered at 24 V AC/DC all day?

Coil dissipation at the 24 volt input is low; the relay runs cool enough for plug-in socket mounting without forced airflow.
