TWI-SLX: Loop-Powered Two-Wire Slide-Wire to 4-20mA Converter/Isolator
Function:
The TWI-SLX is an isolated two wire Slidewire transmitter in a small,
easy to install package. It has easily accessible screw terminals and
is built in a rugged housing. The many different input ranges allow it
to be used in a great variety of position and/or deflection measurement
applications.
