Description

ICS Triplex T8314 Trusted Fibre TX/RX Unit

Configured to extend the Trusted Expander Bus through a single-mode fibre-optic link, the ICS Triplex T8314 (T8314 Trusted Fibre TX/RX Unit) converts differential copper Expander Bus signals to optical signals and restores them at the remote end. The unit supports a communication distance of up to 10 km and operates as an independent transmitter/receiver interface within the Trusted remote Expander architecture. (manualzz.com)

The T8314 accepts dual 24 VDC feeds through diode ORing. Internally, the Expander Bus signal passes through isolation, filtering, and termination before optical conversion. The remote T8314 reverses this process and returns the signal to the copper Expander Bus. (manualzz.com)

TMR Safety Communication Architecture

The Trusted architecture uses three independent T8314 communication paths to provide a non-interfering fibre communication arrangement. Each unit operates independently and requires no configuration before installation. Therefore, maintenance personnel can replace an individual unit without interrupting the complete Trusted system operation, subject to the system configuration and maintenance procedure.

The optical interface operates at 250 Mb/s. For redundant fibre paths, the propagation-time difference must remain within 80 ns, corresponding to a maximum fibre length difference of 15 m. For routes exceeding 2 km, the cable route should be surveyed to verify propagation-time and system timing requirements. (manualzz.com)

Frequently Asked Questions (FAQ)

Q: What power supply does the T8314 require?
A: The T8314 accepts 18 VDC to 32 VDC and provides two 24 VDC input paths with diode ORing. Maximum power consumption is 1.7 W. (manualzz.com)

Q: What fibre interface does the T8314 use?
A: The unit uses single-mode fibre with SC connectors and separate Tx and Rx fibres. The specified communication distance reaches up to 10 km. (manualzz.com)

Q: What installation constraint applies to redundant fibre paths?
A: The maximum propagation-time difference is 80 ns, corresponding to a maximum fibre length difference of 15 m. Routes exceeding 2 km require propagation-time verification. (manualzz.com)

Field Installation Guidelines

• Mount the T8314 on a TS32 or TS35 DIN rail in either horizontal or vertical orientation.
• Provide sufficient clearance around the unit for fibre routing and connector access.
• The installation manual specifies a minimum 200 mm clearance on either side for the fibre cable bend radius. (manualzz.com)
• Connect the two 24 VDC supply inputs according to the specified polarity and terminal assignment.
• Use separate Tx and Rx single-mode fibre connections with compatible SC connectors.
• Keep fibre routing within the permitted bend radius specified by the selected cable manufacturer.
• For links longer than 2 km, verify the physical route and propagation-time difference between redundant fibre paths.
• Do not connect or disconnect the equipment while energized unless the installation area meets the applicable safety requirements.
• Observe ESD precautions when handling the unit or exposed connectors.
• Verify communication through the Trusted Expander Interface and Processor diagnostics after installation. (manualzz.com)
