Description
The T8311C Trusted TMR Expander Interface is a high-reliability communication module designed for use within the Trusted Controller Chassis. It acts as the primary gateway between the internal Inter-Module Bus (IMB) and external Expander Bus networks, enabling scalable multi-chassis system architectures using standard UTP cable connections.
Applications
Petrochemical Refineries: Used in SIS nodes for secure long-distance ESD transmission via optical links.
Thermal Power Plants: Enables high-speed I/O exchange between turbine and boiler control racks.
Coal Gasification Plants: Applied in gasifier islands with strong isolation against electrical noise.
Offshore Platforms: Provides short-range rack-to-rack communication using TC-301 cables in marine environments.
Steel Plants: Ensures stable multi-channel data synchronization in high-temperature control systems.
Features
Triple Modular Redundant (TMR), fault tolerant (3-2-0) operation
Hardware Implemented Fault Tolerant (HIFT) architecture
Dedicated hardware and software test regimes which provide very fast fault recognition and response times
Automatic fault handling without nuisance alarming
Hot replacement
Front panel indicators that show module health and status.
T2V Certified IEC 61508 SIL 3
Installation
To install the module:
1. Ensure that the cable assembly is correctly located.
2. Release the ejector tabs on the module using the release key. Ensure that the ejector tabs are fully open.
3. Holding the ejectors, carefully insert the module into the intended slot.
4. Push the module fully home but pressing on the top and bottom of the module fascia.
5. Close the module ejectors, ensuring that they click into their locked position.
FAQ
Q1：Can T8311C be installed on DIN rail or third-party PLC racks?
A: No. It is dedicated to Trusted T8300 chassis only with proprietary electrical and mechanical interfaces.
Q2：Can T8311C use TC-301 copper cable for 50 m rack connection?
A: No. TC-301 is limited to 30 m; longer distances require fiber conversion.
Q3：What is the power dissipation of T8311C under full load?
A: It is limited to a maximum of 40W.
Q4：Will T8311C fail in -20°C environments?
A: Possibly. Minimum operating temperature is -5°C; heating is required below this.
Q5：Does T8311C require extra licensing for 250Mbps bus speed?
A: No. The 250Mbps bandwidth is a native hardware capability.
