Analog to Frequency
Models 8605, 8606, 8607
analog input modules are designed
to interface with the 24 VDC logic inputs for applications
requiring additional analog inputs. The 8600 modules output
a square wave up to 500Hz allowing the PLC to count the
frequency producing about 8 bit resolution, 1 part in 500.
The 8600 module has an isolated floating optocoupler transistor
which provides DC isolation from the input, output and DC
power. The output transistor is fully floating allowing either
source or sink connection to the PLC.
The modules are housed in a plastic case with a built in U-foot
for mounting on standard DIN rails. The case dimensions,
excluding the U-foot, are 1.65" H x 1.06" W x 3.78" L.
Connections are made to screw clamp terminals that accept
wire sizes 22 to 16.
