Mounting
There are 4 holes in the PCB for mounting. You can use our mounting set to place the print. You can find
this in the webshop.
Connecting the wires
The most common use of the HPP4 is in combination with the OC32 accessory module, therefore we are
explaining how te connect the module to the OC32.
You can connect the print according to the example below:
V +: Connect this directly to the V + your power source
V- from K1: You can connect this to a pin of the OC32
V- from K2: You can connect this to a pin of the OC32
V- from K3: You can connect this to a pin of the OC32
V- from K4: You can connect this to a pin of the OC32
The banks of the pins on the OC32 to which you connect the relay must have a SINK driver. But you can
find more about this in the OC32 manual at www.vpeb.nl
You can connect the relay outputs according to the example applications. These can be downloaded via
