Product information
Overview
Key Features
- Analog I/O capacity: Has 4 analog inputs for current or voltage differential signals and 2 analog outputs for current or voltage.
- Signal ranges: Inputs support ±10 V, ±5 V, ±2.5 V, 4 to 20 mA, and 0 to 20 mA; outputs support -10 V to +10 V, 0 to 20 mA, and 4 mA to 20 mA.
- Resolution and cycle time: Provides up to 14 bit resolution; current inputs provide 13 bit resolution, and the maximum cycle time for all channels is 625 μs.
- Supply and consumption: Rated supply voltage is 24 V DC; typical current consumption is 60 mA, with 80 mA typical from the backplane bus at 5 V DC.
- Diagnostics: Has alarms, diagnostic functions, supply-voltage monitoring, wire-break and short-circuit diagnosis, plus LEDs for input, output, and maintenance status.
- Protection and connection: IP20 protection; shielded twisted-pair cable is supported up to 100 m.
