.3 Signal Loop Testing of Industrial

Machinery

Two types of measurements are typically
made with industrial machinery: current
measurement with a 4- to 20-mA current
output, and voltage measurement with a
signal 1- to 5-V or 1- to 10-V loop.

Example

Measure temperature with the thermocouple
[K], converting transducer output to 4- to 20­mA. Observe output on the controller and
record changes. Transducer power is included
in the signal loop.

A typical device configuration for this
example is described below.

1. Transducer Input
Substitute thermocouple output to the

transducer with the signal source. Set the
source mode to the thermocouple source (TC:
RJ) function, and thermocouple [K]. Refer to
Section 3.2, "Thermoelectric Power (TC: 0℃/
RJ) Generation" for connections to the
transducer including the TEMPERATURE
PROBE.

―――――――――――――――――――――――――――

2. Transducer Output
The power source and the ammeter at the

transducer output are replaced by the 7011
constant voltage (CV: 25 V) and current (A:
25 mA) functions. The 7011 output terminals
connect to the power source terminals, and
the current measurement terminals replace
the ammeter, so connections to the output
side of the transducer can be handled by a
single unit.

3. The output of the unit at the transducer input
sets the transducer input conditions, and the
other unit at the transducer output measures
the 4- to 20-mA output.
