AC Output Modules
Solid state I/O switching modules deliver an electrically clean, photo-isolated,
noise-free "output" interface from
logic level control systems to external
loads such as motors, valves, solenoids,
etc. -- or an "input" interface from the
load or sensors to microprocessor or
computer-based logic level systems.
Designed for long, reliable service in
demanding industrial environments.
