E-T-A Circuit Breakers’ new Smart Power Relay is designed to provide reliable switching, protecting and monitoring of PLC-controlled resistive, inductive or lamp loads in DC 24V systems. The new plug-in Smart Power Relay E-1048-S6xx is designed to protect against overload, short-circuit and wire break that can result in costly damages and long downtimes, the company says. The E-1048-S6xx is an optimized, purely electronic relay offering protective monitoring and diagnostic functions. It features wear-free operation and permanent monitoring of the load circuit in case of wire break. Available versions are rated from 0.5A to 4A in a space-saving width of only 12.5 mm. The new relay model is suitable for a wide range of operating temperatures up to 60 degrees C. The integral time/current characteristic has the E-1048-S6xx respond similarly to a thermal circuit breaker for equipment protection with additional remote disconnection and reconnection. The current status is indicated by means of two LEDs. In the event of a failure, the device has a double failure indication: visually by means of a red LED and electronically by an opto-coupler in the signal output. Its triple functionality as an electronic relay, an overcurrent protection device and a diagnostic device makes the E-1048S6xx a powerful replacement for a whole series of plug-in connections, helping to avoid possible failure sources, the company explains.
