KTA-223 USB/RS485 Relay IO Board
Descripción: El KTA-223 es una placa con 8 reles que puedes conectar ya sea por un dispositivo USB o un módulo de control RS-485: Esto podría ser muy útil para controlar dispositivos del mundo real, tales como iluminación, sistemas de riego, lectura de sensores o interruptores de control y otras señales digitales.
El controlador está basado en el hardware de plataforma Arduino. Puede ser programado como un controlador independiente que utiliza el entorno de programacion libre. Internamente, el controlador es "Compatible con elescudo Arduino", lo que permite el uso de tarjetas de extensión (Shields) muchas de ellas diseñadas para la Arduino uno.
Los relés son capaces de conmutar hasta 5A 250VAC, 10A a 120V y 10A a 24VCC.
Con el firmware por defecto, y un protocolo ASCII simple permite el control de Windows / Mac / Linux a través de cualquiera de los controladores USB o puertos RS485 virtuales. Además, varios dispositivos pueden ser conectados a un bus RS485, permitiendo el control de muchos dispositivos de un puerto USB.
Un gran número de terminales con tornillos de acoplamiento se incluyen con este producto. El cable USB no esta incluido.
Nota: Para conseguir que esto funcione con la versión R3 de la plataforma Arduino Ethernet shield tendrá que conectar el contacto 1 de los pines de ICSP a D12, D13 y al pin 3 y 4 a la D11.

KTA-223 USB/RS485 Relay IO Board
sku: DEV-09526
The KTA-223 Relay Board is a USB or RS485 controlled module that can interface a PC to eight or more SPDT relays. This could be very useful for controlling real world devices - such as lights and sprinkler systems - and reading sensors or monitoring switches and other digital signals.
The controller is based on the hardware of the extremely popular Arduino platform. 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.
The on-board relays are capable of switching up to 5A at 250VAC, 10A at 120VAC and 10A at 24VDC, but the PCB traces can only handle up to about 5A.
With the default firmware, a simple ASCII protocol allows control from Windows/Mac/Linux using either USB Virtual COM drivers or RS485. Additionally, multiple devices can be connected to one RS485 bus, allowing control of many devices from one USB port.
A large number of mating screw terminals are included with this product. USB cable not included.
