Reliance Automax. In stock ships today. 45C20. 4520. Programmable Controller. Automate 20 Host. Local Head Mode. Rail Mode. First turn off power to the Reliance device that will be connected to the analog rail module. Set the \"mode\" switch on the faceplate of the module to the desired position. Connect the I/O rail cable between the Analog Rail connection labeled \"input\" and an I/O port on the Reliance device that will communicate with the module. Recall that the Mode switch is read each time the Reliance device connected to the Analog Rail module is powered up. The Analog Rail installation is now ready for testing. For DCS 5000, Automax, or Distributed Power D-C Drive Systems, test output channels by writing a value between 0 and 4095 to those channels and using a voltmeter to verify that the signal on the terminal points (0 to 10V) is proportional. Local Head mode allows all four channels on the module to be updated at the end of the scan (normal I/O rate in this configuration), or during the scan using AIN and AOUT blocks. Rail mode allows only one channel to be update at the end of the scan, or all four channels to be update during the scan if AIN and AOUT blocks are used. In Rail mode, the Analog Rail module is imaged in one I/O register of the processor. Data from one of the four channels will occupy the register as a function of the channel select bits. The active channel is updated at the end of each scan. For input channels, the two channel select bits in the register must be set to the appropriate input channel number.
