5.2.16 Connecting to a Digital Input Module
The Digital Input Module (DIM) has two modes of operation. A DIM channel may be configured to generate an alarm, fault or
warning signal when activated.
Alternatively, a DIM channel may be configured to provide remote control of a selected group of one or more input / output
channels. The DIM may be used to remotely reset, inhibit, or acknowledge the selected channels.
When used for inhibit, repeated activation toggles the inhibit state of the selected channels.
Note: It is the user's responsibility to guard against unauthorised inputs when using remote switches, buttons or keys.
