Description

The TW301 is a low cost, reliable, potentiometer input, 2-wire transmitter for field or panel mounting in various industrial housings and enclosures.  It provides a DC output current proportional to the slide position of a potentiometer.

Low-drift amplifiers, and filtering and conditioning to reduce susceptibility to transients and noisy operations provide accurate, trouble free operation.  Optional conformal coating of the electronic components makes the TW301 extremely reliable and resistant to the corrosion, moisture and fungus associated with many industrial environments.

The module utilizes a stable 1.2 V power supply to excite the potentiometer.  Any value potentiometer from 1 kilohm to 50 kilohms can be used.  The output ZERO and SPAN controls are accessible through the top of the case. 

Terminations are made to screw terminal connectors on the top of the case.

Typical Applications

Remote tank level, valve or actuator position data acquisition.

Mounting

The TW301 can be mounted in a connection head (TSH-A6L) or on a flat surface using the two 5/32 inch holes provided. The 17/64 inch center hole allows clearance for a 1/4 inch diameter temperature probe.
