This compact I/O system now has M12 connections

| By Chemical Engineering



This company has expanded its product line of extremely compact Simatic ET 200AL IO (input-output) systems to include modules with the M12 connection system (photo), higher output currents and longer maximum distances between modules. Analog and digital actuators and sensors, such as IO-link devices, can be connected to the new M12 modules, which have up to 16 digital inputs. The high channel density reduces both the wiring effort and the space requirement for higher-quantity structures. As the output current is now twice as high, actuators with a current consumption of up to 2 A can be connected. Groups of actuators can be shut down safely according to SIL2 via the ET 200AL outputs. — Siemens AG, Munich, Germany
