GfG Instrumentation 4000195 GMA400-AT24 ACDC Module with 24 Analog Inlets

In many industries, it is not uncommon to see extensive systems covering large distances. To reduce the wiring effort, groups of up to 24 transmitters can be connected to an AT24 module using three-wire lines (4-20mA). The GMA400-AT24 transmits the measured values of the analog measuring points to the GMA400 via Modbus connection. The distance between the GMA400- AT24 and the controller can be up to 1200m. ACDC-capable transmitters, such as the CC33 for combustible gases or the IR22F for CO₂, offer the unique benefit of sending additional digital information (such as time-weighted average values, manual alarms or measured values that are insensitive to signal fluctuations) to the GMA400. Likewise, ACDC-capable transmitters receive commands from the GMA400 as if they were wired digitally. Remote calibrations, for example, can be initiated directly at the controller, which significantly reduces the time and effort required for service work on transmitters that are difficult to access.
