This Harmony RE17R timing relay can be set between 0.1 seconds and 100 hours, has an output rating of 8A, is 17.5mm wide and can be supplied with 24V DC, 24V to 240V AC. It also has 1 changeover contact SPDT (single pole double throw). It has one of market slimmest form-factors, allowing for a flexible and easy installation on DIN rail, using the same space as any modular 1-pole DIN device. It also offers a sealable cover, simple and precise settings with rotary trimmers. Single function timer for a simple integration in hard-wired logic schematics, ideal for refurbishment of old installations without using a PLC.
