ABB Bailey NCIS01 I/O Slave Module | 8 Universal Channels

The ABB Bailey NCIS01 manages local I/O points under a master controller’s direction. This slave module handles both digital and analog signals for field devices. It weighs approximately 0.62 kg and occupies a single Bailey rack slot. Its dimensions measure 25.4 cm in length, 12.7 cm in width, and 3.2 cm in height.

Technical Specifications & Hardware Details

The NCIS01 features eight universal I/O channels configurable for input or output use. A single 48-pin backplane connector links this slave module to the master controller. This unit stores no energy internally because it contains no batteries. Three main components form the complete assembly: the PCB, the faceplate, and the backplane interface.

Configuration and Field Wiring

You can configure each channel individually using the master controller’s software. For terminating field wiring, connect this module to NTCS series termination units. The universal design reduces spare part inventory across your facility. A front-panel LED indicates communication status with the master controller.

Installation and Operational Data

You can mount this slave module into any open slot of a Bailey INFI 90 rack. The module draws 240 mA from the 5V backplane supply during normal operation. Furthermore, it operates reliably within a 0°C to 60°C temperature range. Consequently, the NCIS01 requires zero scheduled maintenance. Just inspect field wiring connections during routine plant shutdowns.
