The model 20/6 is a precision, loop powered 2-wire transmitter with galvanic
isolation between its input and the current-loop output signal. The 20/6 provides the
necessary circuitry for amplification, rectification and processing of AC Current or
Voltage signals from various sensors and signal sources. An optional LCD indicator is
available on the 20/6 to indicate the output in Engineering Units.The 20/6 can be easily
ranged without requiring special tools or board modifications. The model 20/6N is a
special version intended for very low current/voltage measurements and higher voltages
over a wider frequency range of up to 2KHz. A TEST terminal provides a 40-200 mV signal
proportional to the 4-20mA output. Applying a DVM to the TEST terminals allows monitoring
and verification of the output without interrupting or disconnecting the current
loop.
