The ABB RAIO-01 is an Analogue Input/Output (I/O) extension module designed to seamlessly integrate with ABB’s higher-level control systems, most notably the AC 800M series of controllers. It is a fundamental component for expanding the analogue signal handling capabilities of an automation system, allowing for the connection of a wide range of field instruments like sensors (temperature, pressure, flow) and actuators (valves, drives).
The part number 3ABD64606841 REV H specifies the exact hardware revision and manufacturing code.
Key Features
-
Module Type:Â Analogue Input/Output (AI/AO) Extension Module.
-
Compatibility: Primarily designed for use with ABB AC 800M Programmable Logic Controllers (PLCs) and their associated I/O system (S800 I/O).
-
Function:Â Provides 8 channels that can be individually configured as either Analogue Input (AI) or Analogue Output (AO).
-
High Channel Density:Â The 8 configurable channels in a single module slot offer excellent space efficiency in the control cabinet.
-
Flexible Signal Ranges:Â Supports a wide variety of standard industrial signals:
-
Analogue Input (AI): 0/4-20 mA, 0-10 V, ±10 V, RTD (Pt100, Pt1000), Thermocouple (T/C) types J, K, L, N, R, S, T, U, E, B.
-
Analogue Output (AO): 0/4-20 mA, 0-10 V, ±10 V.
-
-
Isolation:Â Features channel-to-channel and channel-to-bus isolation, which is critical for noise immunity, signal integrity, and protecting the system from ground loops.
-
Hot Swappable:Â Supports replacement without powering down the entire system (when used in a compatible hot-swap rack and with proper engineering procedures), minimizing downtime.
-
Communication:Â Connects to the controller via a high-speed, proprietary fieldbus (typically Profibus DP-V1 or, in newer systems, via S800 I/O Link).
-
Diagnostics:Â Comprehensive built-in diagnostics for channel status, wire break, short circuit, and out-of-range signals.

Typical Applications
The RAIO-01 module is used across a vast spectrum of industries for process control and monitoring:
-
Process Industries:Â Chemical, Oil & Gas, Pharmaceutical, Water/Wastewater treatment.
-
Manufacturing:Â Automotive, Food & Beverage, Pulp & Paper.
-
Energy:Â Power Generation (thermal, hydro, renewable).

HVAC:Â For controlling large building management systems.
Example Functions:
-
Reading a 4-20 mA signal from a pressure transmitter (AI).
-
Reading a temperature from a Pt100 sensor in a tank (AI).
-
Sending a 4-20 mA signal to control the speed of a pump (AO).
-
Sending a 0-10 V signal to position a control valve (AO).
System Integration
The RAIO-01 is never used alone. It is part of a larger ecosystem:
-
Controller:Â An AC 800M CPU (e.g., PM851, PM861, PM891).
-
Communication Interface:Â An S800 I/O Communication Interface (e.g., CI871 for Profibus, CI854 for TCP/IP) that links the I/O rack to the controller.
-
I/O Rack:Â An S800-LI or similar rack that houses the modules and provides power and communication.
-
Base Unit (Terminal Block):Â AÂ TB-01Â terminal unit is physically attached to the front of the RAIO-01 module to provide the screw terminals for field wiring.
-
Engineering Software: The module is configured and programmed using ABB’s Automation Builder or its predecessor, Control Builder M.
