Application

The module RM4220 is a strain gauge amplifier. This amplifier offers a very
simple and practical calibration of the zero point and the final value by using
DIP-- switches and potentiometer. The excitation voltage is selectable with 5
or 10 V. The output signal is 0/10 V or  10V and 4/20 mA.
The connection of the transducer is either possible in 4-- or 6--wire technique.
If you use the 6--wire technique, you can neglect the effects on resistance va-
riation of the extension wire. The housing made of polyamide PA typ PHOE-
NIX EM can be hooked up with every DIN EN support rail. (EN 50022 stan-
dard)

Mounting / Dismounting

The housing is installed onto mounting rails to DIN EN 50022; they are hoo-
ked onto the upper edge and snapped into the spring plate on the lower edge.
For dismounting, use a screwdriver to push down the spring plate and unhook
he housing.
