0 Channel, 2-Wire REMOTE CONTROL K8023 ma vices fro e d 0 1 up to wires.
Features & Specifications Features: Microprocessor controlled. Inputs can be push-buttons, switches or open collector outputs from another device. The receiver section provide 10 open collector outputs which allow you to control relays directly. Terminal block connectors for all input and output connections are included. All outputs are provided with LED indication.
Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: A good quality soldering iron (25-40W) with a small tip. Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections.

Hook-up & testing 13. Hook - up & Testing Connect both PCB’s P8023S and P8023R according to fig.1. Both push buttons and switches can be used to control the inputs. Keep the distance between the switches or push buttons and the circuit as short as possible. If the circuit is used in a noisy environment (e.g. proximity of electric motors, transformers, ….) or if the distance between the switches and the circuit exceeds 1m (3"), a shielded cable must be used to connect the switches.
Operation 14. Operation 1. Control section (P8023S): Both PCBs are connected to each other by means of two wires, VTX+ and VTX-. They supply power to the control board and carry the data signal. This signal contains information regarding the status of the 10 inputs. Filtering and regulating of the power supply is performed by VR2, together with C15, C12, C13 and C14, which also suppress possible oscillation of the voltage regulator.
