7. 3 wire device providing an unsourced open collector NPN transistor output The term unsourced means that no voltage is applied to the output from within the flowmeter It must be pulled to a high or on state by 5 24V supplied from an external source typically the receiving instrument The pulse output between signal and OV is a voltage square wave with the high level being the DC voltage available at the open collector and the low level being OV The receiving instrument must incorporate a pull up resistor typically greater than 10kQ which ties the open collector to the available DC voltage level when the Hall sensor is not energized When energized the open collector output is pulled to ground through the emitter OV The power supply requirement is 5 24 Voc 20 MA max Voltage Pulse Output Fx A self generating 2 wire voltage pulse output with 1 5V voltage spike of approximately 10 microseconds duration is generated with no dependence on rotor speed Reed Switch Pulse Output Rx The reed switch output is a two wire normally open SPST voltage free contact ideal for installations without power or for use in hazardous area locations simple apparatus when Intrinsically Safe I S philosophy is adopted When using the reed switch output the liquid temperature must not change at a rate greater than 18 F per minute In general the reed switch life will exceed 2 billion actuations when switching less than 5V at 10mA The
