## DUAL 3-WIRE POTENTIOMETER SMART MODULE

8-pin Input

Connector.

Dual 3-wire pot inputs and +2.5 V excitation.

Ultra-low Noise

16-bit A/D Convertor.

Ratiometric operation on both inputs.

Approaches 19-bit performance

with additional software filtering.

Interface to

Tiger Meter.

State-of-the-art

Electromagnetic Noise

Suppression Circuitry.

Ensures signal integrity under harsh EMC environments.

Crystal

Controlled 50/60 Hz

Noise Rejection option.

On-board Digital

Signal Processor.

Optimized signal full scale and averaged output rate.

The interface solution for linear position transducers.

With dual inputs, the ISR3 and ISR4 can excite and perform ratiometric data conversion on two linear potentiometers. Combined with the Tiger 320 Series operating system, this smart module is the design answer for industrial and process control applications involving accurate and continuous linear displacement and/or rate-of-change measurements at up to 100 Hz averaged output rate.

### Smart Setup Registers

The meter has three smart setup register s to configure all smar t input modules. The reference voltage and output rate for both input signals are configured in smart register 1.

Potentiometer signals, POT 1 and PO T 2, are then individually softw are selected for a combination of tw o meter channels. Either signal can be selected for Channel 1 via Code 2, Channel 2 via Code 4, Channel 3 via Code 5, and Channel 4 via Code 6.

### Programming Procedures

The following programming procedures cover all the steps required to configure smart input module ISR3 and ISR4. Steps 1 to 5 describe how to select the line frequency rejection and the output rate through smart register 1.

Steps 7 to 12 describe how to select the output registers for Channels 1, 2, 3, or 4 as required.

Press the

and

buttons at the same time to enter the main programming mode.

Press the

button three times to enter Code 2. Set Code 2 to [X77].

Note the output register map is different for each smart input module.

This setting enters the smart register 1 code setup menu.

Press the

button.

This men u pro vides settings unique to smart register 1 of the ISR3 and ISR4 input module.

5 Press the

button. The display returns to [Cod_2] [X77].

6 Using the

button, reset the 3rd digit to z ero [X70] to leave the smart register 1 menu.

Note, leaving the 3rd digit as 7 means the displa y constantly cycles between [Cod_2] and [SMt1].

## Select a Channel

Select the output register for the required channels
