The IMO XBF-AH04A is a versatile combined analogue input and output expansion module designed for IMO XGB programmable logic controller systems. It provides 2 analogue input channels and 2 analogue output channels, allowing a PLC to both monitor analogue process signals and generate analogue control signals from a single compact module.
As part of the IMO XGB analogue expansion range, the XBF-AH04A supports 1–5 V DC, 0–5 V DC, 0–10 V DC, 4–20 mA and 0–20 mA signals on both its input and output channels. Voltage or current operation is selected using the module's channel selection switches together with the corresponding PLC configuration.
The XBF-AH04A uses 12-bit binary conversion with a maximum resolution of 1/4000, accuracy of ±0.5% or better and a maximum conversion speed of 1 ms per channel. This combination makes it suitable for applications requiring compact bidirectional analogue signal processing for sensors, transmitters, drives, actuators and other industrial equipment.
Combined analogue I/O modules allow a PLC to acquire continuously varying process signals while also generating analogue commands for external equipment. The IMO XBF-AH04A provides two input and two output channels in one module, making it suitable for closed-loop control applications where sensor feedback and analogue control outputs are required within the same automation system.
Its support for common 0–10 V DC and 4–20 mA signals enables integration with pressure, level and flow transmitters as well as variable speed drives, valve positioners and other analogue-controlled equipment. Configurable filtering and averaging functions can help stabilise measured signals, while the multiple analogue output ranges provide flexibility when interfacing with different field devices.
