Siemens SM322 Digital output, isolated, 16DO, 20-pole, 4A Part number 6ES7322-1BH01-0AA0

16 Digital output modules permit the output of digital signals from the PLC to the process by converting the internal signal level of the S7-300 into the external signal level required by the process. They are suitable for connecting solenoid valves, contactors, small-power motors, lamps and motor starters, for example. By design the digital output modules feature the following mechanical characteristics are compact design, easy to install and User-friendly wiring.

Digital output modules convert the internal signal level of the controller (logical "0" or "1") to the external signal level required by the process. Apart from cost-effective, easy-to-handle digital output modules, modules with special functions are also available for process engineering.
