Technical Data

Safe inputs are fixed to the STO function.

When STO function (Safe Torque Off) is not needed, then all STO inputs must be connected directly with +24 V. The STO function is then bypassed and cannot be used.

I/O hardware data

  • Reference ground is DGND
  • Galvanic isolation for 60 VDC
  • Activation delay about 5 µs
  • De-activation delay about 500 µs
  • Use 24 VDC ±15% PELV power supply
  • High level 17 VDC to 30 VDC, 5 mA to 6 mA
  • Low level 0 VDC to 5 VDC, max.1 mA
