Basic Information

Document ID: EP03-490-520, Release 520, Version 1.5

Scope of application: Expert Series-C I/O modules and C300 controllers, supported since the Expert R300 version

Core component definition:

IOTA (Input Output Termination Assembly): A component that integrates I/O module fixation and on-site wiring functions. The module is directly plugged into IOTA without the need for an additional chassis

IOM (Input Output Module): A module equipped with core electronic components to achieve specific I/O functions and obtain power from IOTA

Core functions and design highlights

1. Universal design advantages

Compact integrated architecture: IOM and field terminals are integrated into IOTA, eliminating the need for independent electronic component chassis, significantly reducing device size, and improving cabinet space utilization

Convenient wiring and maintenance: using two-level "separable" terminals, convenient for on-site wiring installation and later maintenance; Supports up to 12AWG (2.5mm ²) multi strand wire access

Simplified power supply and redundancy: The on-site power supply is provided through IOTA, eliminating the need for additional power and manual wiring; Redundant configuration only requires adding a second IOM on IOTA, without the need for external cables or control devices

Efficient heat dissipation and layout:

Vertical installation design: Suitable for scenarios where on-site wiring is connected from the top/bottom of the cabinet

Tilted structure: optimizes air circulation inside the cabinet, improves heat dissipation efficiency, and adapts to high-density installation requirements

Information Ring "Identification: Quickly guide maintenance personnel to view equipment status information

Built in protection mechanism: Input/output circuits have short-circuit protection, no need to connect fuses in series, reducing installation and maintenance costs
