In industrial processes where liquids, air or gases are used, valves are needed for dosing and control. These valves are seldom operated manually. Pneumatic valve actuators are normally used for mechanical positioning. The valve position must be monitored electronically. On the one hand to provide a feedback to the controller when a certain position (e.g. "open" or "closed") is reached. On the other hand it is necessary to monitor the valves centrally.

The devices in the IND range contain two inductive sensors for "open / close" detection of an actuator movement by means of target pucks. The digital output controls the solenoid valve for the pneumatic quarter-turn actuator. The AS-i connection allows direct connection to the yellow flat cable via an M12 insulation displacement connector. LEDs serve as switching status indicators for inputs and outputs.

By using state-of-the-art production technologies it has become possible to incorporate the latest AS-i technology with sensors and switching outputs in a space-saving housing. Mounting is effected using two screws on the quarter-turn actuators, standardised to VDI / VDE 3845. Combined periphery fault and communication error LED at the module provide the user with two important signals during set-up and operation. Two data bits for the first time allow separate evaluation of the "short circuit" and "wire break" situations on the output to generate even more targeted service information. The T modules can be addressed before mounting using the addressing unit via the M12 connector without voltage being applied. With the integrated display the modules can be addressed manually or automatically in the "Easy Startup" operating mode. All these features facilitate mounting, set-up and maintenance for the user and increase uptime of the whole AS-interface system.
