Siemens SIPLUS S7-1200 SM 1222 16-Channel Rugged Relay Module About
The Siemens SIPLUS S7-1200 SM 1222 (6AG1222-1HH32-4XB0) is a ruggedized, high-density digital output expansion module designed to manage complex electrical loads in demanding environments. Based directly on the standard 6ES7222-1HH32-0XB0 module architecture, this premium variant is upgraded with a protective conformal coating. This specialized chemical shield permanently protects internal circuits from heavy condensation, humidity, dust, and corrosive environmental gases.The module expands a Siemens SiePortal PLC system with 16 digital relay outputs, providing comprehensive hardware expansion within a compact 45mm-wide DIN rail profile. Because it utilizes physical mechanical relays, it handles both AC and DC wiring topologies across an operating range of -20C to +60C. Each independent channel supports a continuous switching current up to 2 A, making it perfect for directly piloting field actuators, heavy-duty contactors, and solenoid valves.
