Interface module SB60 is used to adapt 8 digital input signals with electrical isolation to the
signal level of SIMATIC TDC by means of optocoupler. The input signal voltage can amount
to 120 V DC or AC.
The eight digital inputs and the SIMATIC TDC rack are electrically separated. The eight
digital inputs are electrically isolated with respect to one another.
The cables SC62 or SC66 are used to connect the interface modules to the SIMATIC TDC
components (for more information, refer to the SIMATIC TDC Documentation).
● Enclosure for snap-on mounting to rails
