Product information
Overview
Key Features
- Isolated analog inputs: Has 2 analog inputs; the channels are not isolated from each other, but are isolated from the backplane bus.
- Supported signal types: Supports voltage, current, thermocouple, resistance thermometer, and resistance inputs.
- Resolution and conversion: Provides 9/12/14-bit unipolar or 9-bit + sign/12-bit + sign/14-bit + sign bipolar resolution; integration time is parameterizable at 2,5 / 16,67 / 20 / 100 ms.
- Diagnostics and alarms: Has parameterizable diagnostics, diagnostic and limit value alarms, readable diagnostic information, and a red group error SF LED.
- Signal connection: Supports voltage measurement, 2-wire and 4-wire current measurement, and two-wire, three-wire, and four-wire resistance measurement.
- Installation and supply: Uses a required 20-pin front connector, supports removing/inserting with active backplane bus, and has a rated load voltage of 24 V DC with reverse polarity protection.
