DRI-PT
AC Powered Potentiometer Input DIN Rail Signal Conditioner
INSTRUCTION
SHEET
Shop online at omega.comSM e-mail: [email protected] For latest product manuals: www.omegamanual.info
Accepts Potentiometers from
100 Ohms to 100k Ohms
Wide Ranging Zero and Span ASIC Technology
Description
The DRI-PT is a DIN rail mount, potentiometer input signal conditioner with 1800VDC isolation between AC power and the input/output circuitry. The input provides a constant voltage and is designed to accept any 3-wire potentiometer from 100 ohms to 100k
ohms. The eld congurable output is switch selectable providing
a 0-5V, 0-10V, 0-1mA, 0-20mA or 4-20mA DC signal. Wide ranging, precision zero and span pots, used in conjunction with DIP switches, allow 80% adjustablity of offset and gain to transmit a full scale output from any 20% portion of the potentiometer input.
Application
The DRI-PT is useful in transmitting process control setpoints to remote PID controllers or interfacing position or level sensors to data acquisition and control systems. The high density DIN rail mounting offers an extremely compact solution for saving valuable panel space.
Conguration
In a valve positioning application a potentiometer is sometimes used as a feedback signal. Quite often a wide open valve is only a 25% turn of the feedback potentiometer. The DRI-PT can easily be adjusted with the zero and span to provide a fullscale output signal (e.g. 4-20mA) representing 0-25% or even 50-75% of the potentiometer input.
Unless otherwise specied, the factory presets the Model DRI-
PT as follows: Input Range: 0 to 100% Output: 4 to 20mA
For other output ranges, refer to Tables 1 and 2 to recongure
switches SW1 and SW2 for the desired input and output ranges.
WARNING: Do not change switch settings with power applied. Severe damage will result!
Calibration
Note: For best results, calibration should be performed with the intended output load, in the operating environment, mounted on a DIN rail, allowing at least one hour for thermal equilibrium of the system.
1. With power disconnected, set the output and input switch selectors (SW1 and SW2) to the desired ranges (see Tables 1 and 2).

to a Potentiometer Input
DIN Rail Mounting with IQRL Universal AC Power 85 to 265 VAC  Plug-in Terminals
Note: An ACPB rail is required to power the modules. See Ordering Information.
2. Connect the input to a potentiometer. Connect the output to the actual device load (or a load approximately equivalent to the actual device load value) and apply power.
Note: To maximize thermal stability, nal calibration should be
performed in the operating installation, allowing approximately 1 to 2 hours for warm up and thermal equilibrium of the system.
3. Set the input to the desired minimum and adjust the zero potentiometer for the desired minimum output.
4. Set the input to the desired maximum and adjust the span potentiometer for the desired maximum output.
5. Repeat steps 3 and 4, if necessary.
