5. C 104 module size and mounting compatibility INPUTS The board provides sixteen optically isolated inputs These inputs can accept either AC or DC signals and are not polarity sensitive Input signals are rectified by photocoupler diodes while unused power gets dissipated through a 1 8k ohm resistor in series The inputs may be driven by either DC sources of 3 to 31 volts rms or AC sources at frequencies of 40 Hz to 10 KHz Standard 12 24 AC control transformer outputs can be accepted as well External resistors connected in series may be used to extend the input voltage range however this will raise the input threshold range Consult factory for available modified input ranges Each input circuit contains a switchable filter that has a 4 7 millisecond time constant Without filtering the response is less then 40 microseconds The filter must be selected for AC inputs in order to eliminate the on off response to AC The filter is also valuable for use with slow DC input signals in a noisy environment The filter may be switched out for DC inputs in order to obtain faster response Filters are individually jumper selected Filters are switched into the circuit when jumpers are installed in position FLTO to FLT15 OUTPUTS The board s outputs are comprised of sixteen FORM C SPDT electro mechanical relays These relays are all de energized at power on Please note that once your hardware is properly installed in your system you will likely want to run
