Industrial timing relay

The Macromatic TR-50222-10 is a single-function on-delay relay built for control panels and machinery circuits. It accepts 120V AC/DC coil voltage and switches loads up to 10 A at 240V AC or 30V DC through DPDT contacts.

Plug-in octal base installation

The unit mounts in an eight-pin octal socket for quick panel wiring without soldering. A front potentiometer adjusts the delay between 1.8 sec and 180 sec, and the enclosed IP20 housing protects contacts from dust during commissioning.

Suits simple on-delay sequences

This relay fits applications needing one fixed on-delay function such as motor starters, lighting stagger or pump sequencing. It does not serve processes requiring off-delay, repeat-cycle or multi-function timing modes.

Questions about this item

How do I verify the relay is timing correctly after wiring it into the socket?

Apply power and measure the interval between energising the coil and the contacts changing state; it should fall between the 1.8 sec minimum and 180 sec maximum set on the potentiometer.

What comes with the TR-50222-10 and what must I source separately?

The relay itself is supplied; an 8-pin octal socket for plug-in mounting and the 120V AC/DC control supply are not included.

Which time-delay version should I choose for a simple power-on delay?

This model provides a single on-delay function adjustable from 1.8 sec to 180 sec, so it suits applications needing one fixed delay-on-operate period.
