The Control Unit is freely programmable and can be expanded up to max. 86 safe I/O´s.

• 14 safe digital inputs (8x OSSD tolerant)
• 2x2 Lo-Side / Hi-Side outputs
• 2 messaging outputs
• 2 safe relay outputs
• 2 pulse outputs (for diag purpose)
• 2x2 safe analogue input combinations
• Short circuit monitoring
• Multiplying contacts or contact amplification by external contactors, in combination with integrated monitoring is possible
• extensive diagnostic functions integrated in FW
• Coded status display via 7-segment front panel display and status LEDs
• Quit / Start / Reset button can be operated on the front panel
• Expandable to max. 86 safe I/O´s via integrated backplane bus (connector can be snapped into DIN rail)
• Optional fieldbus interface (expansion module for CANopen, ProfiBus/ProfiNet, DeviceNet, Ethercat)

To connect other extension modules to the base module, 3 of T-bus backplane connectors are necessary.
