Inovance GL20-4AD 4-Channel Analog Input Module
The Inovance GL20-4AD is a genuine 4-channel analog input module for the GL20 remote I/O series. It accepts voltage and current analog signals and communicates over the GL20 bus back to the head station, giving PLC and DCS systems extra analog input capacity for pressure, temperature, level and flow transmitters on the plant floor.

Where This Module Is Used
The GL20-4AD is used by panel builders and maintenance engineers who need extra analog inputs on an existing GL20 remote I/O station, or who are building a new GL20 rack for a bottling, packaging or general automation line. It is a common spare part to keep on hand alongside other GL20 series modules, such as the Inovance GL20-0016ETP digital output module and the Inovance GL20-2HC counting module, as well as the Inovance GE20-TF memory expansion card, across Iraq, the GCC and other Arab markets we serve.

Frequently Asked Questions
Does the GL20-4AD accept both voltage and current signals?
Yes. Each of the four channels can be wired for voltage input or current input, so the module works with common industrial transmitters that output either 0-10V or 4-20mA signals.
Can the GL20-4AD be added to an existing GL20 remote I/O station?
Yes. It plugs into the GL20 DIN-rail bus alongside other GL20 modules already installed, so panel builders can expand analog input capacity on a station that is already running.
What power does the module need?
The GL20-4AD is powered by DC24V at 100mA, supplied through the +24V and COM terminals on its terminal blocks, the same power arrangement used across the GL20 module range.
Is this module compatible with other Inovance GL20 controllers?
Yes. The GL20-4AD is designed to work as part of the same GL20 remote I/O family as digital input/output and counting modules, so it can be mixed and matched on one head station to match a specific automation line’s I/O count.
