This is a voltage monitoring relay module that is capable of measuring 1-phase networks. Our E1UM230V01 lets you select a suitable voltage range of 24V AC, 24V DC or 230V AC in one device. The settings go as low as 18V AC/DC all the way to 276V AC. The integrated SPDT (1CO) contact switches right away to trigger an alarm or further actions to prevent damage.
This product is ideal to monitor stationary or remote back up power installations like batteries or even checking on industrial power supplies with a 24V DC output.
All TELE products fulfill EAC, CE, and cULus standards and come in a slim IEC style 17.5mm/0.69in footprint that snaps on a conventional DIN Rail. Besides the local settings, relays and terminals we also offer LED status indication with all of our products.
