ABB Bailey NAOM01 Output Module

This output module provides discrete control for ABB Bailey INFI 90 automation systems. The ABB Bailey NAOM01 features sixteen independent output channels in a single-wide form factor. Each channel delivers 24V DC at 0.5A for driving solenoids and indicator lamps. Consequently, plant engineers can control multiple field devices from a single module.

Technical Specifications of the Output Module

The ABB Bailey NAOM01 measures 180 mm in width and 240 mm in height. Its depth reaches 45 mm for standard INFI 90 rack mounting. The module weighs approximately 0.58 kg including all output and isolation circuitry. A single front panel LED array shows the on-off status for each output channel. The front side features a removable screw terminal block for field wiring connections. This design stores minimal energy in small suppression capacitors only. Therefore, the module contains no batteries or large energy storage elements.

Functional Features and Protection Circuits

The ABB Bailey NAOM01 includes built-in overcurrent protection on each output channel. You can connect outputs directly to inductive loads without external suppression diodes. The module automatically reports short circuit and overload conditions to the controller. Each output also features a green LED indicator for visual troubleshooting. Consequently, maintenance teams can identify faulty circuits instantly without meters.

Installation and System Integration

You must install this output module into a standard INFI 90 rack slot. The ABB Bailey NAOM01 connects to the backplane automatically upon full insertion. A removable terminal block accepts field wiring from 14 to 22 AWG. The module supports hot replacement without powering down the entire rack. Always verify load current limits before connecting multiple devices to one common return.

Maintenance and Operational Benefits

Because the ABB Bailey NAOM01 stores no battery-backed data, it needs no periodic battery changes. Technicians can replace the module without losing any configuration settings. The transparent terminal cover prevents accidental contact with live wires. Consequently, this output module offers safe and simple maintenance for INFI 90 control systems.
