PIN / CONTROL FUNCTIONS
+In / -In DC Voltage Ports The maximum input voltage should not be exceeded. The modules have internal over / undervoltage lockout functions that prevent operation outside of the specified input range. They will turn on when the input voltage rises above its undervoltage lockout. If the input voltage exceeds the overvoltage lockout, the module will shut down until the overvoltage fault clears. PC will toggle indicating an out of bounds condition. PC - Primary Control The output voltage is enabled when the PC pin is open circuit (floating). To disable the module's output voltage, the PC pin is pulled low (referenced to -IN). Open collector optocouplers, transistors, or relays can be used to control the PC pin. During an abnormal condition the PC pin will pulse (Figure 17) as the module initiates a restart cycle. This will continue until the abnormal condition is rectified. The PC pin should not be used as an auxiliary voltage supply, nor should it be switched at a rate greater than 1 Hz.
