Overview
The 6AG1422-1BL00-2AA0 is a Siemens SIPLUS S7-400 SM 422 digital output module delivering 32 outputs at 24 V DC rated load voltage, each channel rated for 0.5 A continuous. The module draws 4.0 W from the backplane and occupies 25 mm on the DIN rail. It is designed for extended environmental conditions: operating temperature from -25 °C to 60 °C, making it suitable for applications outside standard climate-controlled cabinets.
Function & operation
The outputs are short-circuit protected with a typical response threshold between 0.7 A and 1.5 A. The module supports digital input control, meaning the outputs can be read back for diagnostic purposes. Isolation test voltage is 500 V, and the switching frequency for lamp loads is limited to 10 Hz. The signal level for a logic 1 is L+ minus 0.3 V, ensuring compatibility with standard 24 V PLC I/O.
