  • Octal 8-pin plug-in base enables quick socket mounting
  • Operates on 24 V AC/DC coil voltage for flexible integration

Single-Function On-Delay Relay

The Macromatic TR-50228-05 is a single-function time delay relay designed for on-delay timing in control circuits. It operates on a 24V AC/DC coil voltage and features an octal 8-pin plug-in base for socket mounting. The enclosed unit carries an IP20 rating and uses a potentiometer for time adjustment.

Suits Panels Using 24V Control Voltage

This relay suits installations where a single on-delay function is required at 24V AC/DC with 10A DPDT contacts. It is not for systems needing multiple delay functions or time ranges beyond the 0.1 to 10 second window. Buyers who need different coil voltages or contact forms must select another part.

0.1 to 10 Second Adjustable Range

The adjustable timing range spans from 0.1 seconds minimum to 10 seconds maximum via the front potentiometer. This single range determines whether the relay matches the application timing requirement. Verify the needed delay falls within these limits before installation.

Questions about this item

Will the 24 V AC/DC coil work with my existing 24 V control circuit?

Yes, the relay operates on 24 V AC or DC, matching a standard 24 V control supply without modification.

How can I verify the on-delay timing after wiring the octal socket?

Apply power and measure the interval before the DPDT contacts close; the potentiometer adjusts the delay from 0.1 to 10 seconds.

Does the package include the octal socket or must I order it separately?

The relay has eight flat pins for plug-in mounting; a compatible octal socket is not included and must be purchased separately.
