Actuator sensor interface is a field level interface which connects input field elements like push buttons, sensors and feed back elements and output field elements like contactors, relays and solenoids. The input output modules are available in panel mountable or field mountable models. IP 65 protection of the field module enables to locate any where in the field without a need of panel. Safety integrated Modules are also available. All input, output modules can be connected with a single specially manufactured ASI cable which reduced cabling between field elements and CPU. The system can be connected to S7-200 and S7 -300 systems.
