Analog Output Terminals

Typically, AMETEK provides two self-powered analog outputs which do
not require a loop-power supply and are compatible with loop imped-
ances of up to 1000 ohms. Additional outputs can be included if specified
by the customer (for external Water Dewpoint or Water Content). The
two self-powered analog outputs are used for Hydrocarbon Dewpoint
(HCDP) Temperature and Operational Status Code.

For self-powered and/or loop-powered analog output connection loca-
tions, see Figure 3-3.
NOTE
The standard analog output signals are discrete 4–20 mADC, 1500 Vrms
isolated current outputs configured as 2-wire transmitters (Figure 3-3).
The output ranges and measurement units (Figure 3-5) are the default fac-
tory settings. The output ranges can be changed (except the Operational
Status Code – fixed analog). For each output, the lower output range
value (Figure 3-5) corresponds to 4.00 mA and the higher output range
value corresponds to 20.00 mA.
However, when loop-powered V/Is are used, the customer must supply
an external loop-power supply (15–30 VDC) that is capable of supplying
25 mA per loop.
