The Flare Control series of measuring relays has been expanded with new devices that monitor a selectable voltage or current setpoint. The relays measure voltage in three different ranges up to 300 V or single-phase current in three ranges up to 10 A. Both series feature a supply voltage range of 20.4 to 264 Vac/dc. The relays are housed in 22.5-mm-wide DIN rail modules and can be set to switch states when the measured values are either within or outside the specified thresholds. Each relay features two changeover contacts, LED indicators for diagnostics and troubleshooting and plug-in terminals designed for easy wiring connections.
