Configurable Inputs
Configurable inputs are used for general purpose inputs. These inputs can be used with 5, 12, or 24
VDC sensors or switches. Compare the specifications of sensors to the “Oak Specifications” chart to ensure
reliable operation. Inputs are arranged into banks of 4 that can be individually configured for voltage and
polarity. Resistor packs SIP1, SIP2, SIP3, and SIP4 must be changed to match the input voltage for each bank
of inputs. Sinking or sourcing operation is determined by the wiring configuration.

Notice: Do not use 2 wire
sensors. The voltage drop
across 2 wire sensors
usually causes unreliable
operation. If a 2 wire sensor
works when connected, it
still may be unreliable for
long term use.
