SIEMENS 6KA9904 EL1 Transducer 220VAC

The SIEMENS 6KA9904 is a compact SIPART DR20 process controller designed for single-loop closed-loop control of temperature, pressure, flow, level, and other process variables. As the standard-controller variant of the DR20 family, it combines analog current inputs, a continuous S output, and digital I/O in a DIN 43700 panel-mounted housing. It is widely used in power plants, water treatment, and process industries as a standalone PID controller or as a backup/manual-loading station in larger control schemes.
