Universal Speed Relay gGb -r GROUP USR Universal Speed Relay APPLICATION The Speed Relay is a microprocessor controlled digital speed monitor for use with 2, 3, 4 wire NPN/PNP sensors, 4B’s WDA range of sensors or Contact sensor inputs, with a user programable electromechanical relay and PhotoMOS Solid State Relay (SSR) outputs. The Speed Relay has a 160x80 pixel LCD display to provide information, and 3 front panel buttons to program settings. METHOD OF OPERATION The Speed Relay reads input pulses and displays the calculated pulse frequency in a range of selectable units. The user can set the Electromechanical Relay and PhotoMOS Solid State Relay outputs independently, with their own thresholds and output behaviors, and have the Alarm LED indicate the state of one of the outputs. The Electromechanical Relay can be set to trigger when the input speed is outside the chosen range. The PhotoMOS Solid State Relay can provide a trigger output or can be configured to provide a pulsed output that matches the input pulse frequency. One LED (Input LED) shows input status of the sensor’s pulses, and another LED (Alarm LED) shows the state of the assigned output.
