SIEMENS - SIMATIC S7-1500 / ET 200MP - SM 522 Digital Output Modules

The Siemens SIMATIC SM 522 Digital Output Modules provide modular digital output expansion for SIMATIC S7-1500 and ET 200MP automation systems. The family enables PLC-controlled switching of industrial actuators and loads and includes DC transistor, universal-voltage, AC TRIAC and relay output variants to suit different voltage, current and switching requirements.

SM 522 variants are available with different channel densities, output currents, diagnostic capabilities and performance classes, ranging from compact high-feature DC outputs to high-density 64-channel modules and AC/relay switching modules. Depending on the variant, functionality can include single-channel diagnostics, substitute values, switching-cycle monitoring, PWM operation and safety-oriented shutdown of externally controlled load groups.

The modular range allows machine builders, panel builders and system integrators to select the output architecture appropriate to the connected field loads while retaining the common SIMATIC S7-1500 / ET 200MP I/O platform.
