This section describes:
Terminal connectors are used to connect I/O field devices and the power supply to the I/O base. While busbars may also be used, terminal connectors are electrically connected to the module, busbars are not.
Some I/O bases can be operated over dangerous voltage ranges (above 42.4 VAC and above 60 VDC). Coding keys shipped with the I/O base and coding tabs shipped with the terminal connector can be used to prevent the accidental insertion into an I/O base of a terminal connector wired for the wrong voltage range.
NOTE: For maximum protection, key coding is required during installation.
Terminal connectors are available in screw-in and spring-clip versions.
One terminal connector is required for each row of terminals that you will connect to the module's operating voltages and field devices.
Terminal connectors must be ordered separately. They are available in kits of three. They are not shipped with the Momentum I/O bases.
