Product information
Overview
Key Features
- 8 isolated analog inputs: The module has 8 AI; the analog inputs are isolated from the backplane bus and the electronics power supply, but not from one another.
- Multiple input signals: Supported input ranges include voltage, current, thermocouple, resistance thermometer and resistance measurement.
- Resolution and conversion: Resolution with overrange is up to 15 bit including sign; integration time is parameterizable at 2,5 / 16,67 / 20 / 100 ms.
- Diagnostics and alarms: Parameterizable diagnostics, diagnostic alarms on channels 0 and 2, parameterizable limit value alarms and readable diagnostic information are supported.
- Power and connection: Rated load voltage L+ is 24 V DC with reverse polarity protection. The module requires a 20-pin front connector and supports an active backplane bus.
