Applications
- Closed-loop control: Provides 16 closed-loop controllers, with capacity of 16 using thermocouples or 2-wire connection and 8 using Pt 100 or 4-wire connection.
Key Features
- I/O channels: Has 16 digital inputs, 16 analog inputs and 16 analog outputs. Analog input capacity is 16 with thermocouples or 2-wire connection, and 8 with Pt 100 or 4-wire connection.
- Input signal ranges: Supports voltage, current, thermocouple and resistance thermometer inputs, including 0 to +10 V, -1.75 V to +11.75 V, 0 to 20 mA, 4 mA to 20 mA, and Pt 100.
- Analog outputs: Supports 0 to 10 V, -10 V to +10 V, 0 to 20 mA, -20 mA to +20 mA and 4 mA to 20 mA output ranges. Voltage outputs have short-circuit protection.
- Resolution and timing: Resolution with overrange is 14 bit maximum and parameterizable at 12 bit or 14 bit. Conversion time per channel is 16.67 ms, with specified 12-bit and 14-bit alternatives.
- Supply and diagnostics: Rated load voltage is 24 V DC, with a permissible range of 20.4 V to 28.8 V. Substitute values and internal or external temperature compensation are parameterizable.
- Connection and isolation: Requires 2x 48-pin front connectors. Isolation is tested with 500 V DC; channels are not isolated from each other, while channels and the backplane bus are isolated by optocoupler.
