ABB Bailey IIDST03 Digital Signal Transmitter

This transmitter module converts digital field signals for ABB Bailey control systems. You will find the ABB Bailey IIDST03 Digital Signal Transmitter Module relaying contact status and pulse train data to the controller. Its robust input design handles harsh industrial field conditions reliably.

Technical Specifications

This module contains eight digital input channels with programmable debounce filters. You can also locate four status LEDs for individual channel monitoring. The ABB Bailey IIDST03 Digital Signal Transmitter Module stores no battery energy for configuration retention. Instead, it uses optocouplers for all field-to-logic isolation requirements. Therefore, this module never requires any routine battery replacement.

Signal Conditioning Details

The ABB Bailey IIDST03 Digital Signal Transmitter Module draws its operating power from the INFI 90 bus backplane. Each input channel accepts either dry contacts or voltage signals from field devices. You can set the debounce time individually for each channel using software configuration. Moreover, the module counts input pulses up to 1 kHz for flow metering applications. This design prevents false triggering from contact bounce or electrical noise.

Mechanical Integration and Mounting

You must insert the ABB Bailey IIDST03 Digital Signal Transmitter Module carefully into any standard INFI 90 slot. After full insertion, secure the module using the top and bottom metal retaining clips. The module measures exactly 25.5 centimeters in length and 3.2 centimeters in width. Its total weight reaches approximately 0.43 kilograms for straightforward handling. Furthermore, the module includes a front extraction handle for easy removal during maintenance.

Environmental and Storage Guidelines

You should store this ABB Bailey IIDST03 Digital Signal Transmitter Module in an anti-static bag away from moisture. The module operates reliably between 0°C and +60°C ambient temperature. Likewise, keep the unit away from conductive dust or corrosive atmospheres. Because the module uses solid-state components only, it requires zero regular maintenance over its service life.
