Serial Digital Input and Output Controller | |
Serial Digital Input and Output Controller! This controller has so many applications where it can be used. Starting and stopping remote machinery, starting pumps, sensing external switches such as water levels, thermostats. The list is endless. The controller provides eight relay
outputs each capable of switching 5 amps @240VAC and four opto-isolated digital inputs.
All connections to the I/O are via screw connectors.  |

| It is controlled via a computers RS232 serial port which has several advantages
over the parallel port. It can be used with ANY computer and operating system. Serial
cables can be much longer (up to 35 metres) allowing 'remote' control. Use our RS232/RS485
convertors and distance of over a 1000 metres can be obtained. Serial Digital Input and Output Controller can now be Multi-dropped! A new microcontroller has been programmed for the Serial I/O Controller. It allows up to 10 serial I/O controllers to be multi dropped off a RS232 line. Each Serial I/O controller is given an address which is stored in memory. Each controller is controlled by ASCII commands of the format @x Yzz where x is the address, Y is the command and zz is the parameter. It has all the old commands of the original serial I/O controller plus several new ones. The 4 digital counters can act as non resettable and resettable 24 bit counters. How do you multi drop on an RS232 line you might ask. With a simple addition of a diode on the controllers transmit line together with a single resistor tied to common you can multidrop serial devices on an RS232 line. This is because 99.9% of RS232 transceiver ICs switch at about 1.5V. RS485 can be used to give distances up to 1km but RS232/RS485 converters will have to be used. We sell upgrade kits to allow you to convert a serial I/O controller to a multi drop version Download description of the commands and how to upgrade and Cabling diagram for multidropped connections on a RS232 line. All components are provided including a plastic case with pre-punched and silk screened front and rear panels to give the kit a professional and attractive finish as shown in the photos. Gold plated DS PTH PCB. Finished Dimensions (mm): 140Wx110Dx35H. Software This unit can be used with ANY computer and operating system. It can be controlled via a terminal emulator program such as RealTerm or HyperTerminal. NOW
