Description
The Siemens SIMATIC S7-1200 SM 1222, DQ 16×24 V DC/0.5 A provides 16 digital outputs for controlling 24 V DC field devices and actuators. The transistor outputs can switch loads of up to 0.5 A per channel, with a maximum lamp load of 5 W. Siemens specifies a rated output voltage of 24 V DC, with a signal “0” output voltage of up to 0.1 V at a 10 kΩ load and a minimum signal “1” voltage of 20 V DC. The module provides output delays of up to 50 µs from 0 to 1 and 200 µs from 1 to 0 with resistive loads, supporting responsive digital control.
The 16 outputs provide a high channel density for S7-1200 installations and are individually electrically separated from one another, with 500 V AC potential separation between the channels and the backplane bus. The module supports shielded cables up to 500 m and unshielded cables up to 150 m, while diagnostic alarms and individual output-status LEDs assist with system monitoring. With its 45 × 100 × 75 mm housing and approximately 220 g weight, the SM 1222 is suitable for control cabinets and industrial automation systems requiring a larger number of 24 V DC digital outputs.
