Macromatic
Macromatic TR-50226-05 time delay relay 12 V DC 10 A DPDT 0.1 s
Plug-in time delay relay with 0.1 to 10 second on-delay range, DPDT contacts rated 10 A at 12 V DC or 240 V AC, octal base
- Adjustable timing from 0.1 to 10 seconds with potentiometer control
- DPDT contacts switch 10 A at 240 V AC or 30 V DC
- 12 V DC coil voltage suits low-voltage control circuits
- Octal 8-pin plug-in base enables quick socket installation
- IP20 enclosed housing protects internal components from finger contact
Relay Purpose and Use
This Macromatic TR-50226-05 is a single-function on-delay time relay built for 12 V DC control circuits. It suits automation panels, motor starters and sequencing tasks where a fixed delay between signal and contact change is required.
Compatibility Checklist
Verify that the control supply is 12 V DC and that the load does not exceed 10 A at 240 V AC or 10 A at 30 V DC. Ensure an octal 8-pin socket is available for plug-in mounting and that the IP20 enclosure rating matches the panel environment. The delay range runs from 0.1 sec to 10 sec via potentiometer adjustment.
Upgrade Context
This relay replaces any octal-base on-delay unit with a narrower time range or lower contact rating. The jump is worth it when the application needs the full 0.1 sec to 10 sec span and 10 A switching in a sealed IP20 housing.

Questions about this item
Does the Macromatic TR-50226-05 relay come with an octal socket or must I purchase it separately?
The relay uses an 8-pin octal plug-in base; the socket is not included and must be bought separately.
How do I choose between the minimum 0.1 sec and maximum 10 sec delay settings for my application?
Turn the built-in potentiometer to set any on-delay between 0.1 sec and 10 sec; pick the shortest setting that still allows your load to stabilise.
What does the 10 A contact rating mean when the coil runs on 12 V DC in a real circuit?
The DPDT contacts can switch up to 10 A at 30 V DC or 240 V AC, so a 12 V DC coil can control loads well above the coil voltage.
