Description

About the SM 1222, DQ 16x24 V DC/0.5 A

The Siemens 6ES7222-1BH32-0XB0 is a SIMATIC S7-1200 digital output module (SM 1222) with 16 transistor outputs rated 24 V DC at 0.5 A per channel, expanding a CPU rack with additional discrete outputs. Outputs are not internally short-circuit protected, so external fusing or protection is required per channel.

  • CSA
  • UL
  • cULus
  • FM
  • RCM
  • KC
  • Marine Approval

Selection Notes

Each output switches independently (grouped in ones, not fours), so one shorted or overloaded channel does not drag down its neighbors — but because the module has no internal short-circuit protection, size external fusing per channel at or below 0.5 A to protect the transistor stage. The 200 µs turn-off delay with resistive load suits most contactor and solenoid coils; for higher-frequency switching or lamp loads, check the 5 W lamp-load rating against actual inrush current before wiring incandescent indicators directly.

Applications

Driving 24 V DC loads such as indicator lamps, small relays, and solenoid valves directly from an S7-1200 CPU rack without an external output relay module.
