The 20 Universal Signal Input/Analog Output CAN Controller 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, Frequency or RPM 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 a SAE J1939 or CANopen® CAN network. The I/O module provides 8 analog outputs (0-5 V, 0-10 V, +/-5 V, +/-1 0V, 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 packaging in addition to a 12 or 24 V power supply input section suits power generation and large engine applications.
