– Logic input connectors
Each of these 16 inputs can be connected to a voltage-free contact as per
Figure 30. Input status is transmitted by the digital line to the
MX 32 . There is
no alarm when the contact is closed.
Connection
Refer to Chapter 6, on page 27
Configuration
Configured via the COM 32 application
