PT-104

4 Ch, Differential, 24 bits, RTD data logger

The PT-104 Data Logger is a four-channel, high-resolution temperature converter for
use with PT100 and PT1000 type platinum resistance thermometers (PRTs). It can be
used to measure temperature, resistance and voltage.
In PT100, PT1000 and resistance modes, the unit can use a two, three or four-wire
circuit. Four-wire measurement gives the greatest accuracy.
In voltage mode, the input connector can be treated as a differential input with
ground, or as two single-ended inputs.

Power over Ethernet (PoE)
The PT-104 Data Logger can obtain its power from the Ethernet port as a Powered
Device (PD) according to the PoE standard. To use this feature, you must connect the
unit to Power Sourcing Equipment (PSE) such as a network switch, router or power
injector that also supports the PoE standard. Any standard Ethernet cable up to 100 m
(about 328 ft) in length can be used.

Programmer's Guide
All the software that you need for everyday use of the PT-104 Data Logger is supplied
with the unit. For more advanced applications, you can write your own software.
Information on SDK programming is published in a separate guide.
