Signal conditioners

The loop-powered eLine LPI signal conditioner works with most standard signal types, in one unit without jumpers (milliamps, millivolts, voltage, thermocouple, RTD, resistance and potential).

It is PC programmed with the facility to enter tables for special RTD or thermocouple sensors and input/output characterisation by table. Storage space within the compact 13.1 mm wide unit is available for recording calibration, configuration, location and tag number records.

Full Windows functionality for storing information and configuration files makes the LPI straightforward and simple to use, with a USB cable accessory and software (eLine UCI) suitable for configuration of unlimited units. The LPI is designed for 35 mm DIN rail mount.

A second lower cost unit, eLine API, is auxiliary powered and delivers on more common milliamp or voltage inputs, for a standard 4-20 mA output.

Used as a converter, the signal conditioners work to transform any of these signal types into another (4-20 mA output). With input characterisation tables this unit will deliver conversion to any engineering unit, delivering required process output measure.

Signal conditioners may be used for isolating control circuit sections to avoid ground loops, common mode noise and to isolate portions of control systems. The units are also used as boosters to add capacity to overloaded current loops.
