Product page: https://vutlan.com/can-sensors/150-CAN12V1A.html

Function and purpose

The additional power supply is needed only if the number of sensors in a CAN bus chain is more than 12 sensors. CAN-12V-1A supplies power for each additional group of 12 CAN devices (sensors and extensions).

CAN devices and sensors can be chained together. Up to 10-32 CAN devices can be connected in a chain. You can connect CAN sensors or extensions on a CAN bus line.

Physical description

1. "Power 12V DC" - power input.

2. "INPUT" - This port should be connected to a group of sensors towards the main monitoring unit.

3. "OUTPUT" - This port should be connected to a group of sensors further away from the monitoring unit.

4. LED: "Status" (green) - indicates that the appliance is connected and operating.

Please, read carefully the instructions about connecting the unit. Connecting CAN sensors to the wrong CAN port on this device may burn the CAN bus line.

Connecting the device

Please read this article to the end before connecting the device. Connecting CAN sensors to the wrong CAN port on CAN-12V-1A may burn the CAN bus line.

Description:

In our example, we have a monitoring system with a group of sensors (group 1) connected to it. CAN-12V-1A is only needed if we want to connect to the monitoring unit with more than 15 sensors.

Step 1:

Plug CAN-12V-1A into the power supply socket using a Euro Schuko power adapter. The status LED should light GREEN.
Plug all additional sensors (group 2) into the "OUTPUT" port of the CAN-12V-1A power supply unit. Group 2 should have no more than 15 sensors connected in a chain.
All sensors should light ON. If some of the sensors do not switch ON, decrease the number of sensors connected to CAN-12V-1A, and check the status of each sensor again. If successful, continue to the next step.

Step 2:

Connect GROUP1's last sensor to the INPUT port of the CAN-12V-1A module.
Switch the last sensor's TR button to the OFF position in GROUP1. Switch the last sensor's TR button to the ON position in GROUP2.
You can now CONFIGURE the CAN bus in the web interface. See the "CAN Configuration" step below.
