PHG-11TZ+/PHG-12TZ+

Surge Protection Type RTD input temperature converter

PHG-11TZ+  1 input 1 output
PHG-12TZ+  1 input 2 outputs

Input :Two-wire or three-wire RTD signal

Output :DC signal (current/voltage)

    Overview

    The RTD input temperature converter with surge protection function can convert the two wire or three wire thermistor (RTD) signals into DC current signals. It can be intelligently configured, and the actual range of the thermal resistance can be set through computer software. It has the functions of wire breakage alarm and out of range alarm.

    This product requires independent power supply, with isolated power supply, input, and output terminals.

    Note:

    1. PHG-11TZ+ does not include output part 2

    2. The power rail function is an optional function, and users need to specify the power supply method when placing an order

    The selection of power rail connectors can refer to page 89 of the "Annex"

    3. When inputting a three wire RTD, it is necessary to ensure that the three wires are of equal length as much as possible

    4. When inputting a two-wire RTD, safety barrier terminals 4 and 2 must be short circuited
