SM322 SIEMENS Digital Output Module
SIEMENS SM322 D0 8xREL AC230V
SIEMENS SM322 GENERAL INFORMATION
All our SOFTLINK 300 relay outputs convert the internal signal level to the external power level for process control etc. All modules are compatible with Siemens S7-300 and VIPA 300V series, suitable for controlling solenoid valves, contactors, and small-power devices within their permissible level. The output module provides galvanic isolation from the process level, and has LED indicators for supply voltage, error indication, status indication for each channel.
Digital output modules convert the internal signal level of the controller (logical “0” or “1”) to the external signal level required by the process.
Various output voltages support the output of different process signals:
- 24 V DC, rated current 0.5 A/channel
- 24 V DC, rated current 2 A/channel
- 48 to 125 V DC
- 120/230 V AC
Apart from cost-effective, easy-to-handle digital output modules, modules with special functions are also available for process engineering.
