1.  Available version with power 24VDC or 110/230VAC. There is also available the version for wall instalation or DIN rail instalation.wk0300

2.  It has four 16A relay outputs, it is valid to control lighting or electrical plugs. The connection is made with plug-in terminals for easier instalation.

3. RS485 communication and six digital inputs. Lets you to connect various devices in a RS485 bus. Regarding the inputs, they are volt free, so, compatible  uanto a las entradas, are compatible with any type of button, switch or sensor that provides this type of output.

4. Dip switch. The first four switches are freely configurable, can be used for example to configure groups or to set remote address in Modbus RTU system. The switch number 5 is the terminating resistance.

5. Potentiometer. It has a programmable analog input that can be used, for example, to set the time of opening and closing of the blind.

6. I2C bus. Connection via RJ11, it carries bus and 24VDC, so the WK0200 can be installed directly only with a cable, ideal for access control applications.
