The TRICONEX 4210 Remote Extender Module is a remote expansion module specifically designed for industrial safety control systems. It features high reliability, long-distance communication capabilities, and flexible scalability, and is suitable for critical industrial sectors such as oil, gas, chemical, and power. 

Core functions and features

Long-distance optical fiber communication

Uses single-mode fiber (ST connector), supporting up to 12 kilometers (7.5 miles) of unpowered relay-free communication, ensuring the integrity and anti-interference capability of the signal during long-distance transmission.

Suitable for distributed control systems (DCS) and safety instrument systems (SIS), reducing the complexity of on-site wiring and lowering the risk of electromagnetic interference.

High security and redundant design

Complies with SIL 3 safety integrity level requirements, meeting the standards for industrial safety-critical applications.

Both hardware and software adopt redundant design, ensuring that the system can continue to operate even if some components fail, guaranteeing produc

tion safety.

Flexible I/O expansion capability

Supports expansion of digital and analog input/output (I/O) points, with the ability to connect up to 3 remote sites, adapting to different scales of industrial scenarios.

Modular architecture facilitates deployment and maintenance, supports hot-swappable operations, and reduces downtime. Environmental adaptability

Operating temperature range: -20°C to +60°C (some materials mention an extension to -40°C to +85°C), suitable for harsh industrial environments.

Protection level: IP20 or higher, with dust-proof and moisture-proof capabilities.

Communication protocols and rates

Supports standard protocols such as Modbus TCP/IP, compatible with various industrial devices.

Communication rates can be selected from 9.6 kbit/s, 19.2 kbit/s, etc., to meet different scenarios.

Power supply and protection

Supply voltage: 24 V DC (input range 110-240 V AC, output 0-10 V DC).

Features dual redundant power input, overcurrent protection, surge protection (600 W), and lightning protection (4000 V), ensuring stable system operation.
