Key Features
- 8 isolated analog inputs: Analog input isolated 8 AI with no potential separation between the channels, and separation between the channels and backplane bus and between the channels and the power supply of the electronics.
- Multi-signal input support: Supports voltage, current, thermocouple, resistance thermometer, and resistance input types.
- Selectable resolution: Resolution 9/12/14 bits, with resolution with overrange up to 15 bit including sign.
- Diagnostics and alarms: Diagnostics function, diagnostic alarm, limit value alarm, diagnostic information readable, and group error SF (red).
- 20-pole connection with active backplane bus: 1x 20-pole removing/inserting with active backplane bus.
Applications
- Analog signal acquisition: Acquisition of voltage, current, thermocouple, resistance thermometer, and resistance signals.
- Temperature measurement: Temperature measurement with thermocouples and resistance thermometers such as Pt100 and Ni100.
- Resistance measurement: Resistance measurement with 2-wire, 3-wire, and 4-wire connection.
