Eaton ETR2-12 Off Delay Time Relay

The Eaton ETR2-12 Off Delay Time Relay is a timing relay that provides an adjustable off-delay function. It supports a timing range from 0.05 seconds to 100 hours, allowing a circuit to stay activated for a defined interval after a trigger. An off-delay means the output remains energized for the set interval after the input signal ends, then de-energizes. The broad span—from a few hundredths of a second to many hours—lets you tailor delays for fast response or extended hold times without swapping hardware. Because the model number ETR2-12 identifies this device within Eaton's off-delay relay family, it supports clear identification in catalogs and helps engineers locate related products in the same product line. This capability enables differentiation of timing behavior in control or automation schemes, supporting timed de-energization in a variety of applications where a defined post-trigger interval is needed. Using the ETR2-12, technicians can implement simple sequencing, interlocking, or timed de-energization tasks in control loops without adding hardware changes. Its model designation aids maintenance and replacement by keeping sourcing consistent within Eaton's catalog.
