Mini PLC
Arduino-compatible controller with eight relay outputs, four opto-isolated inputs and three 4 to 20 mA or 0 to 5 VDC analog inputs. Interfaces using USB, RS-485 serial or Ethernet. Windows, Mac OS X and Linux compatible. DIN rail mountable.
The KTA-323 is a USB, RS-485, or Ethernet controlled IO module for interfacing PC's to real world applications, such as controlling lights and sprinkler systems, reading sensors and monitoring switches and other digital signals. It's also an Arduino compatible controller and can be programmed with Arduino IDE for stand-alone operation.
The relays are capable of switching up to 5A at 250 VAC. Bi-directional, optically-isolated digital inputs can be wired to NPN, PNP or dry contact (switch) type sensors. Three analog inputs can be used for 0 to 5 VDC or 0 to 20 mA (including industry standard 4 to 20 mA) signals.
A simple ASCII protocol allows control from Windows/Mac/Linux using either USB Virtual serial port drivers or RS-485. Additionally, multiple devices can be connected to one RS-485 bus, allowing control of many devices from one USB port.
Multiple controllers can be connected to one or more PCs in an RS-485 network. Each controller can be assigned an address and will respond to commands addressed to them.
The KTA-323 can also be controlled over the internet. A webpage is served out over the Ethernet port, allowing monitoring of all I/O, as well as manipulating the relays.
December 2013, We now have a mobile version for this website (see pictures), please go to the manual for more details.
The controller is based on the hardware of the Arduino physical computing controllers. It can be programmed as a stand-alone controller using the free, open source Arduino environment. The Ethernet mimics the hardware of the Arduino Ethernet shield, and is fully compatible with the Ethernet Library. Additionally, the unit ships with a globally unique MAC address.
An example program has been written in Visual Basic to show you how to interface with the KTA-323 using a PC.
