| Benefits | A high-precision Heater Element Burnout Detector compatible with a wide-range of heater control methods. Push-in terminals reduce the workload. Scaling NPN or PNP equivalent output. Lineup includes models compatible with many heater control methods; including ON/OFF control; phase control; and cyclic control. High-precision heater burnout alarm with digital measurement. Contributes to preventative maintenance. If the gate function is disabled; the gate input can be used as an undercurrent/overcurrent relay or for motor or lamp loads. Undercurrent detection values can be set separately for CT1 and CT2. CE marking and cUL certified |
