DIC324
Single-wire connection of potential-free contacts
With the single-wire connection, the signal is connected to the relevant cDIx,
where x=0..15. Using an external power supply source, the common wire is connected with
the + of the external power supply source, and - to be connected with the contact -Vin at
the XP10 connector.
3.2.3
Setting the range of input voltages.
Module DIC324 can be used for operation with voltages from 3.2 to 52 Volts (in two
ranges see the table). Trigger threshold per each group of eight input channels is
determined by assemblies of RN resistors, which are installed into the pads XS2, XS3.

3.2.4 Jumpers for the installation of switching load type
Connection of the load to the module DIC324 is carried out using the XP11
connector(type IDC-20).
Connection types:
1. Single-wire connection;
2. Two-wire connection;
3. Digital output mode (level is set by the vVout)
Two-wire load connection
With such a connection, each switching signal is
connected to the contacts via a couple of wires:
+DOx и -DOx , where x=0..7.
Single-wire load connection
Such a connection can be used if the voltages
are switched with regard to the common
ground of other overall potential, in this case
each signal is connected to the cDOx
(x=0...7), and the common wire - to the contact
GND_VOUT of XP11 connectors or any contact
-DOx.
