Discrete I/O bases
Introduction
Modicon
™
Momentum
™
automation platform products are modular in design.
Communication adapters and Processor adapters are designed to work as
functional modules when they are snapped onto a Modicon Momentum I/O base.
This I/O base requires that some type of Modicon Momentum adapter be attached
before it can be functional.
I/O bases t into compact standard housings that can be mounted on a DIN rail or on
panels in a cabinet. They read information from eld sensing devices and control
discrete and analog eld actuating devices. Terminal blocks and bus bars are
available for use with the bases so that these bases can be used to support 2-, 3-,
and 4-wire eld devices.
I/O eld devices and the power supply to the module are connected via three 18-pin
terminal blocks and an optional 1-, 2-, or 3-row busbar. The terminal connectors are
electrically connected to the module, while the optional busbars are not.
Busbars provide a common connection for the eld devices and serve as protective
distribution connectors. Depending on the I/O base and the type and number of eld
devices connected to it, a 1-, 2-, or 3-row busbar may be used.
Terminal blocks and busbars are ordered separately, and are not shipped with the
Modicon Momentum I/O bases. They are available in either screw-in or spring-clip
versions.
