ABB NWIO-01 Watchdog and Digital I/O Module
The NWIO-01 (product ID 64168533) is a watchdog supervision and digital I/O expansion module manufactured by ABB for use in Advant OCS and AC 800M control systems. It integrates field signal processing with continuous controller health monitoring, maintaining supervisor control over system software and optical communication rings.
Digital I/O and System Supervision
The module features 2 individually isolated digital input channels and 2 relay output channels. Inputs accept 24 VDC or 115/230 VAC signals with user-selectable filter times of 1 ms or 8 ms. The relay outputs handle a maximum continuous current of 2 A. Its internal watchdog logic monitors application program execution, operating system functions, dual-port memory, and DDCS optical Special I/O ring communication. Output channel DO2 can be hardware-configured for dedicated watchdog trip control or standard output operation.
