MEDACS2100 Signal Conditioner
Brand: Status InstrumentsThe MEDACS 2100 signal conditioner consists of a family of DIN rail modules, each one having a high degree of functionality.
They accept most common sensor or process signals and have output choices including isolated (4 to 20) mA re-transmission signal, changeover trip relay, normally open relays or various combinations.
For high density systems, dual channel versions are available or for systems that require more local input, single channel versions with an in-built keypad and digital display are available where functions can be accessed via the front panel keys.
Each unit comes complete with a RS485 serial communications port which enables MEDACS to be integrated into a complete process control system.
Unit wiring is simplified and speeded up by using the integral 'power / comms rail' system provided with each unit which removes the need for complicated and expensive back plane wiring.
