Operating voltage: 24 V DC, +30 / −25 % Maximum current (with heating): 11 A |
WARNING Make sure that your power supply is in accordance with the installation environment and local regulations. |
WARNING Only licensed experts may install electrical components. They must adhere to local and state legislation and regulations. |
The device requires an external overcurrent protection device. Protect the device and the cabling with a circuit breaker at operating voltage lines that has the following characteristics. The overcurrent protection device can be a fuse or a circuit breaker.
Property | Description |
---|---|
Current rating | 13 A, with type B, C, or D tripping characteristics (according to IEC/EN 60898-1 or UL 1077) |
Minimum voltage rating | 32 V DC |
Circuit breaker Instead of a circuit breaker you can use a cartridge fuse with class T (slow acting) tripping characteristics. |
2-pole (connected on both V+ and V–) or 1-pole (connected on V+) |
From the electrical interface point of view, WM80 can be considered to have 3 blocks that are isolated from each other:
- Operating voltage
- Outputs: serial data port and sourcing-type analog outputs share the same common signal ground that is isolated from the operating voltage and the device housing.
- Device housing
Check that data is coming to your system.
To configure the device and for further information about wiring, see WM80 User Guide (M212995EN).
