ABB DSRA 110 Terminal Carrier Kit

Description

The ABB DSRA 110 Terminal Carrier Kit is a high-integrity analog input solution designed for industrial automation applications, supporting both single and redundant system configurations. It features 8 current input channels compatible with 0…20 mA and 4…20 mA single-ended unipolar signals, with a fixed input resistance of 250 ohms and 12-bit resolution for accurate signal capture. Key functional capabilities include distributing external transmitter power to each channel, with monitored and current-limited transmitter power to protect connected devices, plus configurable over-range and under-range limits that meet NAMUR recommendation NE43. The kit includes advanced on-board diagnostics and a loop monitoring DI function, with configurable field power output alarm limits for proactive system oversight. It offers enhanced isolation: all 8 channels are isolated as a single group from the module bus and ground, and its power is derived from a 24V module bus supply. Certified to IEC 61508 SIL3 and EN 954-1 Category 4, it meets strict safety standards, and supports HART pass-through communication for seamless integration with smart transmitters. The physical dimensions are 2.0 inches x 10.0 inches x 10.0 inches (5.1 cm x 25.4 cm x 25.4 cm), with a total weight of 2 pounds 7.0 ounces.
