Schneider Electric REXL4TMB7 Time Relay

The Schneider Electric REXL4TMB7 is a compact Harmony timer relay that delivers on-delay timing from 0.1 seconds up to 100 hours, with four changeover contacts (4CO) and a 24 V AC coil. As a single-function Harmony timer in the REXL4 family, it is designed for plug‑in installation via a socket-terminal and can switch up to 5 A on each contact while drawing about 4 W of coil power. Function A, Power-on Delay, defines the on-delay timing mode described in the product data sheet. This unit is intended for sequencing loads in automation circuits, such as lights or pumps, where a precise delay after power-up is required before energizing the outputs. With its compact plug-in form factor and four changeover contacts, it fits small control panels and enables straightforward sequencing of multiple outputs.
