Analog output
The E9T analog output provides a 4-20mA current-Loop with a value proportional to emissions read and
displayed. The analog output transmits the emission value to a passive panel mounted display, PLC or DCS,
remotely placed in a control room.
The 4-20mA current-Loop is a standard in
industrial applications, due to its simplicity of
installation, high immunity to noises and the
possibility to travel long distances with no signal
degrading.
The E9T analog output is classified as ACTIVE
(sourcing power) and an external power source for
current-Loop is not needed.
The output is protected against reverse voltage
polarity, fast voltage transients and maximum
current and it is not galvanically isolated from
control circuit.
WARNING
The output is +24Vdc self-powered. Do not power the
current-loop line by external devices.
Risk of damaging the output port.
Here is an example E9T output current-loop diagram for connection to a remote passive receiver:
Please read the instruction
manual of the Receiver before
connect it to the E9T

output.
