SOURCE CONNECTION
Models 8505, 8506, 8507 analog to frequency converters
offer a cost effective solution for a single or multiple channel
PLC I/O system. They are designed to operate into the
common 24 volt, 7 mA PLC discrete counter inputs. The 4 to
20 mA input Model 8505 provides 1 kHz to 5 kHz output
frequency for a 4 A per Hertz resolution. The Model 8506
voltage input is scaled for 1 mV per Hertz to 5 kHz for 5 volts

input. The Model 8507 voltage input is scaled for 2 mV per
Hertz to 5 KHz for 10 volts input. The output for all modules is
linear to 0.01% with a very high accuracy of better than 0.1%.
Their output is an isolated floating optocoupler transistor
which provides DC isolation from the input and DC power.
Connections are made easily accessible with screw clamp
terminal blocks. The output can be configured to a Sink or
Source connection.
