M-System SV-AA-D Signal Transmitter 4-20 mA 115 VAC

The M-System SV-AA-D Signal Transmitter is an industrial instrumentation device that provides a 4-20 mA current output and is powered from a 115 VAC supply. Brand: M-System; model SV-AA-D. It functions as a field transmitter in control systems, converting measured signals into a standard 4-20 mA current loop that can be read by process controllers, PLCs, or instrumentation panels. Powered directly from 115 VAC, it fits common mains-powered installations without requiring an external DC supply. The 4-20 mA current loop is widely used in process automation for resilience against electrical noise and the ability to transmit signals over long cable runs. This transmitter is designed for use in environments where M-System devices are part of the instrumentation network and supports integration with existing automation architectures that rely on 4-20 mA signaling.
