Trusted SIS Power and Isolation Characteristics

The T8300 provides a physical expansion chassis with a 24 VDC nominal power interface. It accepts 20 VDC to 32 VDC input power while the field supply operates from 18 VDC to 32 VDC.

Furthermore, the chassis supports 40 channels with a maximum field supply current of 2 A per channel. The specified 50 V reinforced isolation applies between power groups and at the field common interface. Therefore, field wiring should maintain the intended isolation arrangement and avoid unintended conductive paths between separate power groups.

As an ICS Triplex Trusted platform component, the T8300 forms part of the hardware infrastructure used in safety control architectures. However, the supplied data does not specify a particular SIL certification level for this chassis alone, so certification claims should be verified against the applicable Trusted system documentation.

Frequently Asked Questions (FAQ)

Q: What input voltage does the T8300 accept?
A: The T8300 accepts 20 VDC to 32 VDC input power, with 27 W specified power consumption.

Q: What is the maximum field supply current per channel?
A: The specified maximum field supply current is 2 A per channel across the 40-channel configuration.

Q: Is the T8300 fuse user serviceable?
A: No. The supplied specification identifies the fusing as not user serviceable.

Field Installation Guidelines

• Mount the T8300 according to the applicable Trusted system mechanical installation documentation.
• Verify the supplied DC voltage remains within the specified 20 VDC to 32 VDC input range.
• Confirm field supply voltage remains within the specified 18 VDC to 32 VDC range.
• Separate field wiring from high-energy switching conductors where practical to reduce electrical interference.
• Maintain the specified isolation between power groups and field common connections.
• Use appropriate protective earth and cabinet bonding practices according to the system installation requirements.
• Do not open or service the specified fusing in the field because the supplied data identifies it as not user serviceable.
• Check terminal polarity, conductor routing, and connector engagement before energizing the chassis.
