Signals
Signals up to a maximum of 120 V (nominal value) DC or AC can be connected at the SB60
interface module.
Yellow LED
The status of the binary interface module outputs (binary inputs for SIMATIC TDC) is
indicated using yellow LEDs (1...8).
Terminal block X2 provides two screw terminals for each signal:
● terminals 12, 22, ... up to 82 for binary signals 120 V
● terminals 11, 21, ... up to 81 for the reference point
