The 12 Inputs, 8 Analog and 1 Relay Outputs CAN I/O Module can extend machine control networks by adding I/O to the CAN bus. The controller features 1 Isolated CAN port for user-defined communications over the bus. It accepts up to 10 analog (0-5 V, 0-10 V, 0-20 mA or 4-20 mA), digital, PWM, pulse (frequency or RPM), or counter inputs. Two voltage references (user configurable as +5 or +10 V) are provided to power external sensors. A digital input and a resistive input allow for additional interfaces. Each input can be configured to measure the input value and send the data to an SAE J1939 or CANopen® network. The I/O module provides 8 analog outputs (0-5 V, 0-10 V, +/-5 V, +/-10 V, 0-20 mA, 4-20 mA) as well as 1 Form C relay output. Diagnostics messages are provided over the CAN network for the status of inputs or outputs. Rugged IP67 rated enclosure in addition to a 12 or 24 V power supply input section suits power generation and large engine applications.
