Description:
The DRC-4720 is a DIN Rail mount, self-contained DC
powered module designed for load cell, strain gage, or
single ended use. The DRC-4720 contains a precision
instrumentation amplifier, filtered output and a built-
in 10V excitation supply capable of driving a 350 ohm
bridge. The 0 to 30mV input range makes it compatible

with most strain gage based load cell or pressure
transducer outputs. The DRC-4720 provides an output of
4 to 20mA. Connections are made via easily accessible
screw clamp terminal blocks. Zero and Span adjustment
potentiometers are located externally as well for easy
access.
