Applications
- Current measurement: The module supports current measurement with 2-wire and 4-wire signal encoders.
Key Features
- 8 analog current inputs: The module has 8 analog inputs and supports current input signals.
- Current input ranges: Rated input ranges include 0 to 20 mA and 4 mA to 20 mA; voltage, thermocouple, resistance thermometer, and resistance inputs are not supported.
- 24 V DC supply: Load voltage L+ and transmitter supply have a rated value of 24 V DC. Reverse polarity protection is provided.
- 16 bit resolution: Resolution with overrange, including sign, is up to 16 bit.
- Encoder connections: Current measurement supports 2-wire and 4-wire signal encoders.
- Diagnostics and isolation: The module has diagnostic functions, diagnostic and limit value alarms, readable diagnostic information, and an SF group-error LED. The analog inputs are not potential-separated between channels, but are separated from the backplane bus and electronics power supply.
