PN 903-8797, Rev A
Analog Output Terminals
Typically, AMETEK provides two (2) self-powered analog outputs which do not
require a loop-power supply and are compatible with loop impedances of up
to 1000 ohms. Additional outputs can be included if specied by the customer
(for external Water Dewpoint or Water Content). The two (2) 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
locations, see Figure 2-3.
The standard analog output signals are discrete 420 mADC, 1500 Vrms iso-
lated current outputs congured as 2-wire transmitters (Figure 2-3).
The output ranges and measurement units (Figure 2-5) are the default factory
settings. The output ranges can be changed (except the Operational Status
Code – xed analog). For each output, the lower output range value (Figure
2-5) 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.
