Parker's PIO modular expandable bus terminal system uses electronic devices to capture a wide variety of control signals from field devices. Connections to the field level can be implemented quickly and reliably with PIO. The PIO offers the convenience of exceptionally simple installation. The individual modules can be installed and removed without any tools. Different modules can be combined with each other within the bus terminal system. Gold-plated contacts guarantee reliable connections between the individual modules. A conducting ground contact adds additional safety.
