Frequency to Analog
Models 8508, 8509, 8510, 8513 and 8514
frequency to
analog converters are designed to operate from the common
24 Volt , 7mA PLC discrete outputs or any source that can
switch 7mA through 3000 ohms. Their input is an isolated
optocoupler diode which provides DC isolation from the pulse
source, DC power and the output. These units will operate
with a DC supply of 22 Volts to 26 Volts. The modules are
housed in a plastic housing with a U-foot for mounting on
standard DIN rails. The unit’s dimensions, excluding the
mounting foot, are 1.65"H x 1.06"W x 3.78"L. Connections are
made to screw clamp terminal blocks.
The model 8508 provides a 4 to 20mA output for a 1kHz to
5kHz input frequency for a 4 µA per Hertz resolution. The
model 8509 voltage output is scaled for 1mV per Hertz to 5kHz
for 5 Volts output and the 8510 is scaled for 2.5 mV per Hertz
to produce 5 volts output at 2kHz input. The model 8513
provides 4 to 20mA output for 400Hz to 2kHz input frequency
for a 10µA per Hertz resolution. Model 8514 voltage output is
scaled for 5mV per Hertz to 2kHz for 10 volts output.
