Macromatic TR-51626-05 Off Delay Time Delay Relay

SKU CH-N8KR-9DPP7

An off-delay time delay relay with a 0.1 to 10 second adjustable range and DPDT contacts rated for 10 amps

  • Off-delay timing from 0.1 to 10 seconds
  • DPDT contacts rated 10 A at 240 V AC or 30 V DC
  • Octal 11-pin plug-in base for quick socket mounting
  • 12 V DC coil voltage matches common control circuits
  • IP20 enclosed housing protects internal components

Single-Function Off-Delay Relay

The Macromatic TR-51626-05 is a single-function time-delay relay designed for industrial control circuits that require a delayed drop-out action. It suits maintenance engineers and panel builders who need a reliable off-delay timer for motor starters, lighting circuits or process sequences. The unit operates on a 12V DC coil and provides DPDT contacts rated at 10 A for both AC and DC loads.

Replaces Mechanical Timers

This relay upgrades older mechanical timing relays or fixed-function modules where an adjustable off-delay is now required. The potentiometer adjustment covers a range from 0.1 sec to 10 sec, so the jump is worth it when precise timing changes are needed without swapping hardware. It fits applications that previously used non-adjustable delay units or simple on-delay relays wired for off-delay behaviour.

Plug-In Octal Installation

Installation is straightforward because the relay uses an 11-pin octal plug-in base that sockets into standard DIN-rail or panel-mount sockets. The enclosed IP20 housing protects contacts from dust, and the flat-pin layout ensures a secure connection. The main risk is wiring the coil polarity incorrectly on the 12V DC supply, which will prevent the timer from functioning.

Questions about this item

Does the 11-pin octal base fit a standard 11-pin socket?

Yes, the relay uses an 11-pin octal base designed for plug-in mounting in a matching socket.

How is the off-delay period set on the potentiometer?

Turn the potentiometer to select a delay between 0.1 sec and 10 sec; the timer starts when power is removed from the coil.

What is the expected contact life at the rated 10 A load?

The DPDT contacts are rated for 10 A at 240 V AC or 30 V DC; actual cycle life depends on load type and switching frequency.
