Single-function cycle-on relay
The Macromatic TR-55126-05 is a single-function time delay relay built for 12V DC control circuits. It uses an octal plug-in base with eight pins and a potentiometer for adjustment. The unit provides DPDT contacts rated at 10 A for both 240V AC and 30V DC switching. Its IP20 enclosed housing suits panel or socket mounting in industrial machinery.
Timing range and contact limits
The delay function operates in Cycle On mode with an adjustable range from 0.1 sec to 10 sec. Contacts carry a maximum of 10 A at the rated voltages; the relay does not offer other timing functions or voltage ranges. Coil power is drawn from the 12V DC supply, and the IP20 rating means the enclosure protects against solid objects over 12 mm but not against water ingress.
Replaces fixed-timer or multi-function units
This relay upgrades installations that previously used fixed-time relays or multi-function modules where only Cycle On behaviour is required. The jump is worth it when a single, potentiometer-adjustable timer simplifies wiring and reduces inventory. It does not suit applications needing On Delay, Off Delay, or One Shot functions, nor circuits requiring coil voltages other than 12V DC.

Questions about this item
Should I pick the .1–10 sec version or a wider range?
This relay covers 0.1 to 10 seconds on a single potentiometer; if your cycle needs fall inside that window the TR-55126-05 fits, otherwise choose a model with a broader span.
What does the 10 A rating mean when the relay is wired into a 12 V DC control circuit?
The contacts can switch up to 10 A at 30 V DC or 240 V AC, so a 12 V DC coil driving a 10 A load stays within the rated limits.
How does the octal plug-in base affect installation and compatibility?
The 8-pin octal socket lets you plug the relay straight into a standard panel mount base — no soldering, quick swap, and the IP20 enclosure protects the contacts.
