PLC Section
Oak has 34 digital inputs, 12 digital outputs, five analog inputs, and one analog output accessible from
the PLC program. Some I/O is dedicated to a particular function. Four inputs are dedicated to supporting the
digitizing probe, and 11 inputs and 3 outputs are used for MPG support. The remaining 16 configurable,
optically isolated inputs and 9 fused relay outputs are available for general purpose use. Check the “Oak I/O
Map” and “Oak Specifications” sections to determine I/O type and capability. Accessory boards can be
connected to increase I/O capacity. See the “PLC Expansion” section for details.
Digital Outputs
Two SPDT and 7 SPST fused outputs are available on board, as well as 3 open collector outputs
designed to connect to the MPG.
