Abstract
Official abstract text for this publication.
An I/O circuit for use with an industrial controller provides a photovoltaic optical isolator communicating between a controller and a field-side of the I/O circuit, the photovoltaic optical isolator eliminating the need for high wattage power dropping circuits for powering the field-side of the I/O circuit from high-voltage field signals. The field effect transistor type transistors permit use of the low-power photovoltaic optical isolator while allowing flexible connections to various field circuit types.
First claim
Opening claim text (preview).
What we claim is: 1. An I/O module circuit for use in an industrial control system comprising: a housing; terminals supported by the housing for receipt of electrical power to be controlled by the I/O module circuit; and a circuit contained in the housing providing: at least one field effect transistor having a source and drain in series between the terminals to control current flow through the terminals according to a first electrical signal received by a gate of the field…
