B803–008 115 Vac Input, Overview
(Original Document)
General Characteristics
The B803–008 115 Vac input module senses and converts switched input signals into logic voltage levels used by the PLC into 8 independent 115 Vac outputs. The module allows for up to eight independently sensed inputs. These inputs can be received from push buttons, limit and proximity switches, as well as other 115 Vac sources.
