imo xbf-ad04a xgb plc expansion module

Why Choose the IMO XBF-AD04A Analogue Input Module?

The IMO XBF-AD04A is a compact 4-channel analogue input expansion module designed for IMO XGB programmable logic controller systems. It converts standard industrial voltage and current signals into digital data, allowing a PLC to monitor analogue sensors, transmitters and process instrumentation in machinery and automation applications.

As part of the IMO XGB analogue expansion range, the XBF-AD04A supports both voltage and current measurement. Each channel can be configured for 0–10 V DC, 0–20 mA or 4–20 mA input signals, providing flexibility when connecting common industrial instrumentation such as pressure, level, flow and position transmitters.

The XBF-AD04A provides 4 analogue input channels with 12-bit binary conversion, a maximum resolution of 2.5 mV for voltage signals and 5 µA for current signals. With an accuracy of ±0.5% or better and a maximum conversion speed of 1.5 ms per channel, it provides dependable analogue measurement for industrial control systems.

Accurate Analogue Measurement for Industrial Automation

Analogue input modules allow a PLC to measure continuously varying process signals rather than simple ON/OFF states. The IMO XBF-AD04A converts voltage or current signals from external instrumentation into digital values that can be processed by the PLC for monitoring, calculations, alarms and automatic machine control.

Support for both 0–10 V DC and industry-standard 4–20 mA and 0–20 mA signals makes the XBF-AD04A suitable for a broad range of sensors and transmitters. Integrated filtering and averaging functions can also be used to reduce the influence of signal fluctuations and provide more stable measurement data within the control program.
