توضیحات
: Function
The MTL5582 connects to a 2-, 3-, or 4-wire resistance temperature
device (RTD) or other resistance located in a hazardous area, isolates
it and repeats the resistance to a monitoring system in the safe area.
The module is intended typically (but not exclusively) for use with
Pt100 3-wire RTDs. Switches enable selection of 2-, 3-, or 4-wire RTD
connection. The MTL5582 should be considered as an alternative, non-
configurable MTL5575, for use in RTD applications where a resistance
input is preferred or needed instead of 4/20mA. The design is notable
for its ease of use and repeatability. The number of wires which can
be connected on the safe-area side of the unit is independent of the
number of wires which can be connected on the hazardous-area side.
The module drives upscale in the case of open circuit detection. Note
that this module is not suitable for use with measurement systems
where the resistance input channels are multiplexed
