- Opto-isolated inputs with monitoring capability (especially in HM740/2 and HM740/3) for polarity reversal or line-fault detection
- Integrates with IHM communication solutions via IP connection
- Robust performance in control-room environments—built for demanding installations
- Mounting via standard DIN-rail profile
- Terminal-block system with plug-in connectors: quick, tool-free assembly and removal
