The KTA-225 has relays with 12 V DC coils and requires an 9 to 15 V DC supply.
This controller is based on the hardware of the KTA-223 controller, but the number of analog inputs has been increased at the cost of the digital inputs. It can be programmed as a stand-alone controller using the free, open source Arduino environment. Internally, the controller is “shield compatible”, allowing the use of many extension boards designed for the Arduino Deumilanove. As shipped the controller is loaded with a sketch or program that receives simple commands over the USB or RS485 serial port and switches relays or responds with the status of the analog inputs.
Multiple controllers can be connected to one or more PCs in an RS485 network. Each controller can be assigned an address and will respond to commands addressed to them.
