DVC741 Product Manual
DESCRIPTION
The DVC741 expansion module is a 12 High-Side (Sourcing) digital (ON/OFF) output
unit designed to work in conjunction with the DVC710 master controller. The outputs
can be configured to drive LED's or valve type inductive loads up to 3 amps each. The
outputs are short circuit protected and have built in open circuit detection that can be
used for system diagnostics. The DVC741 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.
Two connectors P8 and P9 are prov i ded for e l ect r ic al connec ti ons . P8 (30 pin) is the
main input and output connector which protrudes out the side of the enclosure. P9 is a
standard 5 pin M12 Device-Net Compatible connector.
The status of each output is displayed by a green LED located on the top of the module.
If the output is activated, the corresponding LED will turn on as well. If the output being
used has an open circuit, then the corresponding LED will blink slowly (once a second).
If the output is shorted, the corresponding LED will blink fast (four times a second). A
Module Status (R/G LED) and a Network Status (R/G LED) LED are also located on the
top of the module (see INDICATIOR S secti o n bel ow for further details ).
FEATURES
• All outputs source voltage to the loads.
• Outputs are programmable to work with heavy loads or light loads (LED’s).
• Controller Area Network (DVC Devicenet) provides high-speed serial
communications with up to 16 other CAN compatible devices.
• DVC Devicenet Devices may Co-exist with J1939 devices on the same Bus
without interference.
• Rugged encapsulated enclosure withstands harsh environments commonly
found in mobile applications.
• User friendly display shows output and communication status.
• RS-232 communication used for troubleshooting and node assignment.
