Single-function on-delay relay

The Macromatic TR-50228-10 is a single-function time-delay relay built for industrial control panels. It provides an on-delay timing function suited to motor starters, lighting circuits and process-sequence automation.

Octal plug-in with IP20 enclosure

The relay mounts in an 8-pin octal socket and carries an IP20 rating for finger-safe indoor use. Its enclosed body accepts 24V AC or DC coil voltage, while the potentiometer adjustment spans 1.8 to 180 seconds.

10-amp DPDT contacts at 240V AC

The DPDT output contacts switch up to 10 amps at 240V AC or 10 amps at 30V DC. This rating defines whether the relay can drive the intended load directly or requires an interposing contactor.

Questions about this item

Should I pick the 1.8-second or 180-second version of this relay?

This single model covers the whole range from 1.8 seconds up to 180 seconds, so you adjust the potentiometer to the exact delay you need.

What does the 10 A contact rating mean when the relay is controlling a load?

The contacts can switch up to 10 A at 240 V AC or 10 A at 30 V DC, so size your load within those limits.

How does the octal plug-in base affect installation and voltage handling?

The 8-pin octal socket accepts 24 V AC/DC coil voltage and lets you plug the relay in without wiring each terminal individually.
