RK-4 - Relay Module
Key points:
- RK4 is a relay module with 4 independently switchable relays
- It can be controlled in two modes: analog control or via a ribbon cable connection
- In analog control mode, a 0-10 V input is used to control each relay independently
- Ribbon cable connectors on the bottom of the module allow daisy-chain connection of multiple RK4 modules to increase the number of relay outputs.
