Single-Function Interval Relay

The Macromatic TR-50521-10 is a single-function time delay relay built for industrial control panels and machinery automation. It provides an interval-on delay for sequencing motors, heaters or lighting circuits in a compact plug-in package.

Adjustable 1.8-Second to 5-Minute Range

The delay period is set via a front-mounted potentiometer and spans from 1.8 sec up to 5 min. This single adjustment determines whether the relay suits the required process timing, so verify the needed interval before installation.

Octal Base Plugs Into 8-Pin Socket

The unit mounts by plugging into a standard octal socket, requiring 240 V AC coil supply and offering DPDT contacts rated at 10 A for both 240 V AC and 30 V DC loads. The enclosed IP20 housing fits inside a cabinet without extra sealing hardware.

Questions about this item

What does the 1.8-second minimum delay mean when the relay is installed in a control circuit?

The relay will not start timing below 1.8 seconds, so the shortest interval you can set before the contacts change state is 1.8 seconds.

How does the octal plug-in base limit the way this relay connects to a panel?

The eight-pin octal base only fits a matching octal socket, so the relay must be plugged into that socket rather than wired directly to a terminal strip.

What clearance is needed behind the panel for the enclosed plug-in body to seat properly?

The enclosed housing requires enough depth behind the panel for the full relay body to insert into the octal socket without obstruction.
