Summary |
IRDH275B-427 is Bender’s DIN-rail insulation monitor for unearthed AC/DC IT systems up to 1000V. It continuously watches the first insulation fault from 1kΩ to 10MΩ and trips in <5s, giving two relay outputs plus Modbus-RTU so you can log the event or shut down a drive before a second fault causes a fire or shock. One 24-240V wide-range supply, –25°C…+70°C rating and plug-in terminals mean it fits almost any panel worldwide without extra hardware. |
