ABB Bailey LMUSM04 Universal Simulation Module

This simulation module generates test signals for ABB Bailey INFI 90 system validation. You will find the ABB Bailey LMUSM04 Universal Simulation Module replacing field sensors during loop checks and commissioning. Its programmable output capabilities support multiple signal types for comprehensive testing.

Technical Specifications

This module contains four independent simulation channels for flexible signal generation. You can also locate one configuration switch for address selection on the front panel. The ABB Bailey LMUSM04 Universal Simulation Module stores no battery energy for waveform retention. Instead, it uses non-volatile memory for all programmed output settings. Therefore, this module never requires any routine battery replacement.

Signal Generation Details

The ABB Bailey LMUSM04 Universal Simulation Module draws its operating power from the INFI 90 bus backplane. You can program each channel independently for different signal types and ranges. The module simulates thermocouple types J, K, T, and E with automatic cold junction compensation. Moreover, the frequency output generates square waves for speed sensor simulation. This design allows complete loop testing without connecting actual field devices.

Mechanical Integration and Mounting

You must insert the ABB Bailey LMUSM04 Universal Simulation 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 0.48 kilograms for straightforward handling. Furthermore, the module includes a front extraction handle for easy removal.

Environmental and Storage Guidelines

You should store this ABB Bailey LMUSM04 Universal Simulation 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.
