Macromatic TR-51622-10 Off Delay Time Delay Relay

SKU CH-RNP3-47X35

Single-function off-delay relay with 1.8 sec to 3 min adjustable timing, 120 V AC/DC coil, DPDT contacts rated 10 A at 240 V AC or 30 V DC, 11-pin octal plug-in base, IP20 enclosed

  • Off-delay timing prevents premature load shutdown
  • Adjustable 1.8 sec to 3 min range covers diverse sequences
  • DPDT contacts switch 10 A at 240 V AC or 30 V DC
  • 120 V AC/DC coil suits common control voltages
  • Octal 11-pin plug-in base enables quick installation

Single-Function Off-Delay Relay

The Macromatic TR-51622-10 is a single-function time delay relay designed for industrial control circuits requiring an off-delay function. It operates on a 120V AC/DC coil voltage and features an octal plug-in base with 11 pins for socket mounting. The unit provides DPDT contacts rated at 10 A for both 240V AC and 30V DC loads.

Adjustable Timing via Potentiometer

The relay offers a single off-delay function adjustable between a minimum setting of 1.8 sec and a maximum of 3 min using an integrated potentiometer. This allows precise timing control for motor starters, lighting circuits or process automation without external components. The enclosed housing carries an IP20 rating for finger-safe protection in panel installations.

Suited for Panel-Mount Control Panels

This relay suits engineers and maintenance technicians building or repairing 120V control panels that need a single, socket-mounted off-delay timer with 10 A switching capacity. Buyers requiring multiple delay functions, different coil voltages or DIN-rail mounting without a socket should look at alternative relay types.

Highlights

  • Off-delay timing prevents premature load shutdown

Questions about this item

When will the potentiometer on the TR-51622-10 need replacement?

The potentiometer has no published cycle rating; plan inspection during scheduled panel maintenance and replace if adjustment becomes erratic.

What limit appears first during continuous operation at 10 A?

The 10 A contact rating at 240 V AC or 30 V DC is the first electrical limit; sustained loads at that level will reach thermal steady-state inside the enclosed IP20 housing.

How much heat does the relay produce when powered all day at 120 V?

Coil dissipation at 120 V AC/DC is low; the enclosed IP20 body runs warm but stays within the 10 A contact thermal design for continuous duty.
