ABB Bailey NASM03 Analog Slave Module

This analog slave module acquires field sensor data for ABB Bailey distributed systems. You will find the ABB Bailey NASM03 Analog Slave Module transmitting process values to the master controller via dedicated bus. Its compact design fits efficiently into INFI 90 series equipment racks.

Technical Specifications

This module features eight differential analog input channels for high accuracy. You can also locate one configuration switch for address selection on the front panel. The ABB Bailey NASM03 Analog Slave Module stores no battery energy for configuration retention. Instead, it uses non-volatile EEPROM for all calibration and range settings. Therefore, this module never requires any routine battery replacement.

Signal Acquisition Details

The ABB Bailey NASM03 Analog Slave Module draws its operating power from the INFI 90 bus backplane. You can set the module address using the front rotary switch between 0 and 15. The differential inputs reject common-mode noise up to ±5 volts effectively. Moreover, the module samples all eight channels simultaneously for true concurrent acquisition. This design ensures perfect time correlation between related process measurements.

Mechanical Integration and Mounting

You must insert the ABB Bailey NASM03 Analog Slave 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 0.46 kilograms for straightforward handling. Furthermore, the front panel includes a green status LED for module health indication.

Environmental and Storage Guidelines

You should store this ABB Bailey NASM03 Analog Slave 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.
