HW 17 is designed for mounting on top hat rails (TS35) in switching cabinets and housings. This microprocessor-controlled device monitors the temperature at a defined measuring point. Display of actual or limit value. There are two buttons on the front for adjustment of limit value and device setup.
Depending on the configuration, the relay (change-over contact) switches self-locking or resetting. Self-locking can be time-delayed. The lock is released by pressing the reset key on the device or by disconnecting from the power supply. The operating status is indicated with a LED. The relay switches ohmic loads 1-pole up to 250 VAC, 3 A, we recommend using external contactors or relays controlled by HW 17. Wiring with convenient screw terminals..
