The Schneider 140CRA21120C   IO module (Input/Output module) is a high performance product from Schneider Electric. The following is a detailed description of the module:

I. Product overview

Brand: Schneider

Model:  140CRA21120C

Type: Quantum DIO Fiber optic repeater, which belongs to the Modbus Plus protocol field bus fiber optic repeater

Origin: May be produced in Switzerland or other production sites worldwide (specific origin may vary depending on production batches and supply chain adjustments)

2. Technical specifications and functions

Voltage: 24V DC (for most industrial automation applications)

Current: Support 100-400A range of current (the specific current value may vary depending on the
actual application scenario and configuration)

Interface:

Independent dual-bus electrical interface: supports the Modbus Plus protocol

Two optical fiber interfaces: provides redundant dual-bus structure and optical fiber redundancy ring
network function

Network topology:

Supports point-to-point communication, chain network, star network, redundant double network and
self-healing protection of fiber ring network

The logic independent dual bus electrical interface can realize the backup of the electrical interface or
the single device can connect to the dual redundant bus system

Dual optical ports are used to implement redundancy in the dual-fiber ring network. When an optical
fiber is faulty, the system will rebuild the network link within 10ms to ensure normal communication

Transmission distance and rate:

The optical fiber transmission distance can reach more than 20km

Communication rates up to 1Mbps (Modbus Plus protocol)

Other features:

Support for predetermined communication rates in standard specifications

Provides 6 two-color LED status indicators for monitoring fiber link and power failure

With lightning protection, overcurrent, surge protection and other electrical safety features

Industrial grade design, IP30 protection grade, suitable for harsh industrial environment

3. Application scenarios and advantages

Application Scenario: The Schneider 140CRA21120 IO module is widely used in industrial automation
and control systems, especially where high-speed, long-distance and reliable transmission of Modbus Plus bus signals is required.

Advantages:

High performance: supports high-speed long-distance transmission to meet the needs of industrial
automation systems for data transmission speed and distance.

High reliability: Provides redundant dual-bus structure and optical fiber redundancy ring network
function to ensure the stability and reliability of system communication.

Flexibility: Supports multiple network topologies and can be flexibly configured based on actual
application scenarios.

Easy maintenance: Two-color LED status indicator and relay alarm output are available for users to
monitor and diagnose system status
