Key Features & Benefits
-
8 Differential Current Inputs: Accepts 0 to 25 mA signals from industrial transmitters and sensors for high-precision measurement
-
16-Bit Sigma-Delta Converter: Delivers exceptional accuracy with ±0.05% basic accuracy at 25°C and zero error of ±0.005%
-
Single-Channel Galvanic Isolation: Each input channel is individually isolated from all others and from the PLC, eliminating ground loops and protecting against electrical faults
-
Per-Channel Encoder Power Supply: Generates an isolated 24 VDC supply (max. 30 mA) for each channel, simplifying field device wiring
-
Two Operating Modes: Supports continuous conversion mode (independent of the application) and trigger mode for simultaneous conversion of all channels via an external command
-
Robust Input Protection: All inputs are protected against accidental connection to supply voltage up to 30 VDC and reverse polarity
-
Comprehensive Status Indication: LED indicators for conversion function, operating mode, filter time, encoder power supply status, and module power supply
-
Full Compatibility: Fully integrates with B&R 2005 system base units and expansion units, supported by B&R Automation Studio
