Enabling manual set point adjustment from within a hazardous process area,  the BA427E generator incorporates a bold five digit display which can be calibrated to show the engineering variable represented by the 4/20mA current, plus a thirty one segment bargraph showing the output current.

Backwards compatible with the earlier BA405C, the BA427E has additional features including five pre-set outputs, an extended temperature range, an easy to change scale card and a lower list price than its predecessor.
