This Harmony RE22 modular dual function timer can be set between 1 seconds and 300 hours. It provides function A and function Aw and it is mountable on DIN rail. This modular dual function timing relay is ideal for providing timing control in automation systems such as automatic door opening, alarm, lighting in toilets and car park barriers. It has one of market slimmest form-factors with 22.5mm width, allowing for a flexible and easy installation on DIN rail, using the same space as any modular 2-pole DIN device. It also offers a sealable cover, simple and precise settings with rotary trimmers. Selectable timing range offers a one stop solution for your power management system. Dual function timer for a simple integration in hard-wired logic schematics, ideal for refurbishment of old installations without using a PLC.
