TRICONEX 4351B TCM Time Communication Module

TRICONEX 4351B TCM Time Communication Module Technical Specifications

1. Physical Size & Weight

• Overall Dimension (Height × Depth × Width): 430 mm × 300 mm × 31 mm, standard long rack card for Tricon chassis
• Net Weight of Single Module: 3.18 kg
• Shipping Package Weight: 4.5 kg

Note: Dimension parameters of 120×45×22 mm and 0.5 kg do not apply to 4351B, which belong to other miniature modules.

2. Power Supply & Power Consumption

• Input Power: 24 V DC supplied by Tricon backplane
• Maximum Power Consumption: ≤50 W
• Isolation Withstand Voltage of Communication Ports: 500 V DC

3. Hardware Interface & Timing Function

• Dual RJ45 Ethernet Ports (NET1, NET2): 10/100 Base-T auto-adaptive; NET1 supports SNTP and GPS timing synchronization as well as peer-to-peer UDP clock sync
• 4 DB9 Serial Communication Ports, RS232/RS485 auto-switchable, max baud rate 115200 bps per port
• Timing Feature: Supports Trimble GPS clock synchronization, cross-cabinet peer time sync to realize high-precision SOE timestamp for the whole system

4. Supported Communication & Timing Protocols

Timing Protocols

SNTP, Trimble GPS Timing Protocol, Peer-to-Peer UDP Clock Synchronization

General Communication Protocols

TriStation, Modbus RTU/TCP, DNP3, TSAA, TCP/IP, ICMP, JetDirect Printing

Remark: 4351B module does not integrate OPC server function; OPC function is only available on 4353 and 4354 modules.

5. System Compatibility

• Compatible with TMR triple modular redundant SIS systems with Tricon v9.6 and above firmware versions
• Hot-swap supported; online replacement will not interrupt system control and timing service

6. Environmental Parameters

• Operating Temperature: -20 ℃ ~ +60 ℃
• Storage Temperature: -40 ℃ ~ +70 ℃
• Industrial Application Standard: Suitable for petrochemical and power industry control cabinets; MTBF ≥ 100,000 hours

7. Core Functions

1. Realize master-slave Modbus communication to connect plant-wide DCS and SCADA systems
2. Provide unified plant time benchmark and high-precision SOE event sequence recording
3. Cross-cabinet peer clock synchronization to guarantee uniform timestamp of distributed SIS interlock signals
4. Provide TriStation software interface for remote configuration download and equipment diagnosis
5. Access external GPS clock source to supply standard unified time for the whole factory system

8. Model Difference Comparison (4351B / 4352B / 4353)

• 4351B: Standard TCM time communication module, dual copper RJ45 Ethernet ports, no built-in OPC server
• 4352B: TCM module equipped with dual fiber optical Ethernet ports
• 4353: Ethernet module with integrated OPC server function
