DESCRIPTION
The DVC722 expansion module is a 40 digital (ON/OFF) input unit designed to work in
conjunction with the DVC710 master controller. The DVC722 module provides Low-
Sided (sinking) inputs that all have individually programmable features including
variable de-bounce time, active high/low select, and momentary or toggle options. The
DVC722 communicates with the DVC710 controller through the HCT CAN Bus (high-
speed communication) and utilizes a separate RS-232 port for programming, updates,
monitoring, diagnostics and features such as setting the MAC ID (node) number e.t.c.
The controller is packaged in the standard DVC series enclosure and fully encapsulated
to withstand the fluid power harsh operating environments.
Three connectors (P19, P20, and P21) are provided for electrical connections. P19 (30
pin) and P20 (18 pin) are the main input and power connectors which protrude out the
side of the enclosure. P21 is a standard 5 pin M12 Device-Net Compatible connector.
The status of each input is displayed by a green LED located on the top of the module.
If the input is active then the corresponding LED will light. A Module Status (R/G LED)
and a Network Status (R/G LED) LED are located on the top of the module (see
INDICATORS section below for further details).
