Single-Function On-Delay Relay
The Macromatic TR-50226-10 is a single-function time delay relay designed for control circuits requiring a fixed on-delay sequence. It operates on a 12 V DC input voltage and switches loads through DPDT contacts rated at 10 A. The unit plugs into an octal socket for straightforward installation in panels or machinery.
Adjustable Timing From 1.8 Seconds To Three Minutes
The delay period is set via an onboard potentiometer covering a range from 1.8 sec up to 3 min. The enclosed housing carries an IP20 rating, protecting internal components from finger contact and solid objects. Coil power is drawn from a 240 V AC source while the control input remains at 12 V DC, keeping operational power draw low and noise negligible in typical cabinet environments.
Replaces Fixed-Timer Or Manual Switching Setups
This relay upgrades applications that currently rely on non-adjustable timers or simple manual switches by adding a user-settable delay without rewiring the socket. The jump is worthwhile when a process needs a precise start-up pause between 1.8 sec and 3 min and the existing hardware cannot be recalibrated. It does not suit designs needing multiple delay functions, instantaneous switching, or contact ratings above 10 A at 240 V AC or 30 V DC.

Questions about this item
How do I install the TR-50226-10 relay and what step is often missed?
Plug the 8-pin octal base into a matching socket; the step often missed is confirming the socket is wired for 12 V DC coil voltage before applying power.
What maintenance or replacement will the TR-50226-10 need later?
The enclosed IP20 unit has no user-serviceable parts; replace the relay if contacts no longer switch 10 A at 30 V DC or 240 V AC after extended cycling.
What limit appears first during sustained operation of the TR-50226-10?
Continuous 10 A load at the rated voltages is the primary limit; the on-delay timer cycles between 1.8 seconds and 3 minutes without affecting contact endurance.
