ABB Bailey IMDSI02 Digital Input Slave

This ABB Bailey IMDSI02 module collects digital signals from field devices. It operates as a slave unit within INFI 90 distributed I/O networks. This digital input slave sends status data to master controllers upon request.

Technical Specifications

The ABB Bailey IMDSI02 measures 225 mm in length. Its width reaches 28 mm with a height of 170 mm. This digital input slave weighs approximately 0.55 kilograms. A single PCB assembly holds all input conditioning and communication components.

Design and Energy Storage

This unit stores minimal energy in small filter capacitors. Each input channel uses an optocoupler for electrical isolation. The module filters contact bounce for stable readings. Surface-mount technology boosts reliability in industrial environments. Furthermore, this digital slave includes LED indicators for each input channel.

Installation and Connectivity

You can mount this module into any INFI 90 I/O rack. It communicates with the master via a dedicated serial bus. A removable terminal block accepts field wiring conveniently. Consequently, you complete the installation within a few minutes. Finally, DIP switches assign the slave address on the network.

Performance and Data Reporting

This unit consumes only 3.5 watts during normal operation. Its 4 ms response time captures fast digital events accurately. Thus, you get reliable status data for field devices and switches. The module reports all 32 channels in a single scan cycle. This slave also performs a power-on self-test for each input.

Typical Applications

Use this digital input slave for monitoring turbine limit switches. It also excels at collecting pump status and valve position feedback. Many plants select this unit for remote I/O cabinets. The compact module design saves valuable rack space effectively. Finally, the simple communication protocol reduces master controller workload significantly.
