Features:
- ISOMETER IRDH275 identity: IRDH275B-435 belongs to the documented ISOMETER IRDH275 family.
- Configuration: article B91065101, supply 88...264 V AC or 77...286 V DC, BMS RS-485, 0(4)...20 mA output, and two changeover alarm relays.
- Verification focus: Confirm IRDH275B-435 type, article B91065101, supply-voltage version, and BMS/analog-output requirement before replacement.
Bender IRDH275B-435 is insulation monitoring device designed for unearthed AC, AC/DC and DC IT systems. According to the manufacturer documentation, it continuously monitors insulation resistance and reports alarm conditions through relays, BMS communication, and an analog current output. The ordering code identifies IRDH275B-435 type, article B91065101, supply-voltage version, and BMS/analog-output requirement, so the complete nameplate information should be reviewed whenever the item is being selected for a maintenance replacement, a system extension, or a spare-parts holding.
The technical content for IRDH275B-435 is limited to the manufacturer product page and the cited official datasheet or manual. Final compatibility depends on the monitored system voltage, supply voltage, coupling device if required, BMS address, and alarm thresholds.
The Bender IRDH275B-435 insulation monitoring device is supported by Moore Automated for verified industrial replacement and spare-part requirements.

Compatibility Checks
Confirm the monitored system voltage, supply voltage, coupling device if required, BMS address, and alarm thresholds. The complete IRDH275B-435 marking and nameplate data should be compared with the installed item before a purchase order is released.
Installation Planning
Follow the manufacturer instructions and verify de-energized connection, system coupling, PE connection, relay logic, and BMS termination. Accessories, connectors, cables, sockets, or terminal blocks must be ordered separately unless the quotation lists them.
