The DVC22 Expansion Module is a 40 digital input module for the DVC10 controller. The DVC22 module provides 40 sinking inputs. All inputs have programmable features including de-bounce times, active high/low, and toggle/no-toggle. The DVC22 communicates to the DVC10 controller module through the CAN Bus (high-speed serial communication bus) and utilizes the RS232 port for setting the MAC ID (node) number and for device monitoring. The controller is packaged in a small rugged enclosure and encapsulated to withstand extreme harsh environments.

Three connectors 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. P7 is a standard Device-Net Compatible (CAN Bus 2.0B) 5 pin 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 (Red / Green LED) and a Network Status (Red / Green LED) LED are located on the top of the module (see INDICATORS section below for further details).

Rugged Construction:

¨ Rugged encapsulated enclosure withstands harsh environments commonly found in mobile applications.

¨ All connectors are sealed and the module is encapsulated to withstand extreme conditions in the harsh mobile operating environment.

¨ Operating Temperature: -40 Celsius to 85 Celsius

¨ Reverse polarity protection and transient protection up to 1.5K Watts Peak Pulse Power Dissipation.

Inputs:

¨ Twenty (40) sinking inputs. These require +5 Vdc to +32 Vdc to cause the input to switch from low to high.

¨ Protected against shorts to ground and voltages up to +32Vdc.

¨ Programmable debounce times from 0 to 2.5 seconds.

¨ Programmable latching or non latching modes.

Communications:

¨ Can Bus 2.0B – This port is used to communicate to the DVC10 Master Module.

¨ RS-232 serial port: Setting MAC ID and Baud Rate & monitoring the functions of the DVC22.

Indicators:

¨ Digital Input Status (Qty 40) (Green) – Turns on when the corresponding input is activated.

¨ Module Status (MS) (Qty 1) (Red/Green)

Off – There is no power applied to the module.

On green – The module is operating in a normal condition.

Flashing green – Device in standby state. May need commissioning.

Flashing red – Recoverable fault.

On red – Module has an unrecoverable fault.

Flashing Red/Green – Device is in self-test.

¨ Network Status (NS) (Qty 1) (Red / Green)

Off - Device is not on-line.

Flashing green – Device is on-line but has not established connection to other nodes.

On green – Device is on-line and has established connection to other nodes.

Flashing red – One or more connections are in a timed-out state.

On red – The device has detected an error rendering it incapable of communicating on the network.
