Description

Product Overview

The IMDSO14 is a high-density solid-state digital output slave module for ABB Bailey INFI 90 and Harmony Symphony systems. It provides 16 open-collector discrete outputs to drive solenoid valves, interposing relays, pilot lights and other field discrete devices. It supports both 24 VDC and 48 VDC field load supply, with enhanced EMI protection compared to older IMDSO04. It communicates with multifunction controllers via the slave I/O bus and mates with termination unit NTDO01. Its Symphony Plus equivalent is SPDSO14. It is widely stocked for power, pulp & paper, chemical and refinery interlock and sequence control loops.
