Product description
The DT1612 U (PS) AC voltage transmitters produce an output signal proportional to the true effective value (TRMS) of the input signal.
The transmitter inputs meet the requirements of the CAT III measurement category.
The input measurement ranges can be selected using front-panel switches:

• 0-125 VAC
• 0-250 VAC
• 0-450 VAC

The inputs can be permanently overridden by 20% of the nominal measurement range.
The transmitters have two outputs:

• 0 (4) mA-20 mA DC current *
• 0 (2) V-10V DC voltage *

* only one output can be used at a time
The output signal ranges can also be selected using a front-panel switch.
Transmitter accuracy: 0.2%, in the 40-400 Hz frequency range.
Settling time: 120 ms (max.)
The devices can be ordered with two types of power supply:

• DT1612 U type: 24 VDC ±10%,
• DT1612 U PS type: 230 V AC/DC ±10%

The inputs, outputs and power supply are galvanically isolated from each other, the separation meets the requirements of EN 61010-1.
Front panel indicators indicate the transmitter’s operational status and any error conditions.
The device is a terminal housing design, width: 12.5 mm.
The transmitters fully comply with the requirements of EN 60688.
