Model 8555
Strain Gage to Frequency
Model 8555 analog to frequency converter offers a cost
effective solution for a single or multiple channel PLC I/O
system. It is designed to operate into the PLC high speed
counter inputs. The input range of 0 to 50mV makes the 8555
compatible with most strain gage based load cell or pressure
transducer outputs. The built-in 10V excitation supply is
capable of driving one 350 ohm bridge. The 8555 output for all
modules is linear to 0.01% with a very high accuracy of better
than 0.1%. The 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.
