- Switchable safe outputs pn-, pp-switching for safety-relevant functions
- Monitored relay outputs for safety-related functions
- Extensive diagnostic functions integrated
- Parameter management for expansion modules in the base module
- Coded status display via 7-segment display on the front and status LEDs
- Multifunction button (Quit, Start, Reset) can be operated from the front
- Configurable with SafePLC2 via USB serial adapter or Ethernet-based fieldbus
- Extended functionality:
- Allows the connection of up to 2 encoders per axis (SSI, TTL, HTL proximity sensor)
- Extended encoder interface also supports a high-resolution HTL (200 kHz), sin/cos high-resolution and resolver
- Optional: integrated communication interface:
- Standard and safe fieldbus protocols for communication with a higher-level controller (PROFIBUS, PROFINET, CANopen, EtherCAT, Modbus TCP, PROFIsafe, FSoE)
- Safe cross communication (SMMC) for data exchange between several base devices
- Fieldbus protocols with the same hardware can be switched using SafePLC2
- Safe remote IO communication for data exchange with distributed IO systems
- The mechanical design of the SMX12-2A/2 (/x*) depends on the respective version of the base module
* Optional: integrated communication interface (/DNM, /DBM)
