ABB Bailey NIA001 Analog Output Terminal

This terminal module provides analog output connections for ABB Bailey INFI 90 systems. You will find the ABB Bailey NIA001 I/O Terminal Analog Output Module converting digital control signals to 4-20 mA field currents. Its passive termination design simplifies wiring between I/O cards and final control elements.

Technical Specifications

This module contains eight analog output channels with individual screw terminals. You can also locate two ribbon cable headers for connection to the analog output card. The ABB Bailey NIA001 I/O Terminal Analog Output Module stores no battery energy or electrical charge whatsoever. Instead, it uses only passive copper traces for signal routing. Therefore, this module never requires any routine maintenance or battery replacement.

Signal Routing Details

The ABB Bailey NIA001 I/O Terminal Analog Output Module requires no power supply for its own operation. You can wire each output channel directly to a valve positioner or actuator. The two ribbon headers carry analog signals from the upstream output card to this termination board. Moreover, each terminal pair includes a test point for current measurement without breaking the loop. This design simplifies troubleshooting during system commissioning and maintenance.

Mechanical Integration and Mounting

You must mount the ABB Bailey NIA001 I/O Terminal Analog Output Module onto a standard DIN rail inside the cabinet. After positioning, secure the module using the integrated rail clip at the rear. The module measures exactly 26.0 centimeters in length and 12.0 centimeters in width. Its total weight reaches approximately 0.54 kilograms for straightforward handling. Furthermore, the removable terminal blocks allow quick field rewiring without disconnecting cables.

Environmental and Storage Guidelines

You should store this ABB Bailey NIA001 I/O Terminal Analog Output Module in a clean dry location away from dust. The module operates reliably between -20°C and +70°C ambient temperature. Likewise, keep the unit away from water spray or corrosive chemicals. Because the module contains no active electronics, it offers exceptional long-term reliability with zero power consumption.
