Opto 22 Compatible Pulse Stretch Module

Product development: Design, prototyping, and testing of a signal conditioning module to stretch high speed input pulses. The module enhanced the input capture capability of relatively slow data acquisition systems by providing a 250ms output pulse from input triggers as short as 1ms. Several variants were ultimately produced including one with field-adjustable input levels and output pulse widths.

The prototype modules were field tested in a variety of SCADA and laboratory situations. The proven designs were then mass produced to match the mechanical and electrical aspects of industry-standard Opto 22 modules.
