  • Wide 12 to 240 V AC/DC coil voltage suits many control circuits
  • DPDT contacts rated 8 A at 250 V AC handle standard loads
  • Screw-clamp terminals provide secure wiring without special tools
  • IP40 enclosure protects internals from solid objects over 1 mm

Multifunction Time Delay Relay

The Eaton TRL27 is a multifunction time delay relay designed for industrial control panels and machinery circuits. It provides six selectable delay functions in a single square-base unit. The relay operates on a wide coil voltage range of 12 to 240V AC/DC. DPDT contacts switch up to 8 A at 250V AC for load control.

Replaces single-function timing relays

This unit consolidates flasher, on-delay, on/off-delay, single-shot and trailing-edge modes that would otherwise require separate relays. The upgrade is worth it when a panel needs multiple timing sequences but has limited DIN-rail space. Rotary dip-switch adjustment lets technicians change modes without rewiring. IP40 rating suits enclosed cabinet environments.

Fits standard screw-clamp terminals

The relay mounts on a square base with screw-clamp connections for secure wiring in vibration-prone equipment. It accepts control signals from 24 to 240V AC/DC, compatible with common PLC outputs and sensor supplies. DPDT contact form frees up a pole for auxiliary signalling or interlocking. The compact footprint leaves room for adjacent components in dense panels.

Questions about this item

What panel cut-out and base shape does the TRL27 require for mounting?

The relay uses a square base that fits a standard square panel cut-out; secure it with the integral screw-clamp terminals.

How is the TRL27 wired and which step is most often missed?

Connect the coil to a 12 to 240 V AC/DC supply via the screw-clamp terminals, then set the rotary DIP switch to one of the six delay functions — forgetting to set the switch is the common error.

Which components of the TRL27 may need replacement over time?

The DPDT contacts are rated 8 A at 250 V AC; if the load exceeds this rating or cycles heavily, the contacts will wear and the relay should be replaced.
