Safety Digital Input

SDI 101

Safety Digital Input

  • 10 safe digital inputs (+24 V DC/3.7 mA/0.5 ms)
  • Doubled clock output signal (short circuit proof)
  • SIL 3/PL e, Cat. 4

 

So that inputs can be tested and crossed circuits can be detected, 2 non-safe signal outputs, TA and TB, are provided. To use the SDI 101 in an application, a Safety CPU module is required.

 

For the S-DIAS system, EPLAN Macros are available for simple integration into the control cabinet.
