4.3. Digital inputs
Further, the manager can collect status information and alarm
signals via 32 digital inputs (terminals X3: 2-7, X7: 1-14 and
X8: 1-20). The digital inputs can also be used to block
protection stages under certain conditions. The six digital
inputs in manager X3 use an internal 48 V dc auxiliary voltage
of the manager (terminal X3: 1).
Potential-free contacts must be available in the protected object
for transferring status information to the manager. In VAMP
257 the digital inputs 7-18 in terminal X7 and the digital
inputs 21-32 in terminal X8 need an external control voltage.
