Applications
- High-precision acquisition of up to 4 analogue sensor signals at 16-bit resolution and 0.1% FSR accuracy with individually parameterisable voltage (±5 V, ±10 V, 0…5 V, 0…10 V, 1…5 V, 2…10 V) or current (0…20 mA, 4…20 mA) inputs for demanding measurement and process control tasks
- Electrically isolated signal acquisition with 500 V DC galvanic isolation between all current paths, making this module ideal for applications where ground loops, potential differences, or interference between channels must be eliminated
- Enhanced diagnostics with individual channel-level fault detection alongside module-level diagnosis, enabling precise fault localisation in distributed u-remote I/O stations without taking the entire module offline
- Reverse polarity protected 2-wire sensor connection with 1 ms conversion time and a dedicated status LED per channel for fast commissioning and ongoing supervision in machine and process automation systems
- Hazardous area installations (ATEX/IECEx) and marine applications requiring certified isolated analogue input modules with ABS, ClassNK, DNV, and KR approvals
