(15) Output Terminals
These terminals connect output devices such as electromagnetic switches and solenoid valves. The CPU module is available
in the relay output type (240V AC: 2 A, 30V DC: 2 A), the transistor sink output type (0.5 A), and the transistor protection
source output type (0.5 A).
(16) CAN Port
This port allows J1939 communication.
(17) Ethernet Port 1
This port allows Ethernet communication with connected devices that are equipped with an Ethernet interface.
