Key Features and Benefits
Integrated I/O Functionality: The DSMB127 57360001-HG combines eight inputs and four outputs in a single module. You save rack space and reduce system cost compared to separate input and output modules.
Flexible Signal Configuration: Each channel individually configures for voltage or current signals. Consequently, you connect various sensor types without external signal conditioners or jumpers.
High-Resolution Conversion: Fourteen-bit input resolution captures fine process details for precise monitoring. Twelve-bit outputs provide smooth, accurate control of valves and actuators.
Channel-to-Channel Isolation: Each input and output electrically isolates from others and the backplane. This design prevents ground loops and protects against faults on individual channels.
Comprehensive Diagnostics: The module continuously monitors signal quality and reports wire breaks or out-of-range conditions. You receive immediate alerts for proactive maintenance response.
Detailed Functional Description
The primary function of the ABB DSMB127 57360001-HG involves converting field analog signals to digital values and vice versa. Specifically, it reads signals from transmitters, positioners, and analyzers on its input channels. It then makes these values available to the controller through the backplane for use in control strategies. Simultaneously, it receives digital setpoints from the controller and converts them to analog output signals for valves, drives, and actuators. The module performs these conversions continuously with high accuracy and low latency.
