The ICS Triplex T8830 is a Trusted 40-Channel Analogue Input Field Termination Assembly (FTA) used in the Trusted TMR safety-system family. Its primary function is to provide the field-side interface between analog field devices and the Trusted T8431 Analogue Input Module. Rockwell Automation documentation identifies the T8830 specifically as a 40-channel analog input FTA.
The T8830 is designed for applications where reliable field signal termination and maintenance are important. It supports standard two-wire field-device connections, DIN-rail mounting, 24 VDC operation, per-channel field-power protection, and SmartSlot functionality for online replacement arrangements.

The official-reference-derived description confirms 40 channels, 2-wire field connections, 24 VDC operation, DIN-rail compatibility, SmartSlot capability, per-channel fused field power, and LED indication. Secondary inventory records list approximately 0.7–0.8 kg and dimensions around 160 × 160 × 120 mm.
Functional Description
The T8830 sits on the field-termination side of the Trusted system. It does not replace the T8431 analog input module. Instead, it provides the physical termination and signal interface between field devices and the Trusted I/O electronics.
This distinction matters when sourcing a replacement: T8830 = Field Termination Assembly, while T8431 = Analogue Input Module. The two components work together as part of the Trusted architecture.
Typical Applications
- Emergency shutdown systems
- Fire and gas systems
- Turbine control
- Oil & gas process control
- Chemical processing
- Power-generation facilities
- Critical process monitoring
- Safety instrumented systems
Installation & Configuration
- Verify T8830 on the module label.
- Confirm the connected Trusted T8431 module.
- Check the system wiring and terminal assignments.
- Isolate the relevant field circuits according to site procedures.
- Mount the FTA on the appropriate DIN rail.
- Connect the field devices using the approved wiring diagram.
- Verify the 24 VDC field supply.
- Check each channel’s fuse and LED indication.
- Verify the SmartSlot/system connection.
- Perform channel-by-channel signal testing.
- Confirm correct values at the Trusted controller.
Commissioning Checklist

⚠️ Replacement Note
Be careful with online listings for T8830. Some third-party pages incorrectly describe it as a standalone analog input module or even an Expander Processor. The technical documentation identifies the T8830 as a Trusted 40 Channel Analogue Input Field Termination Assembly.
Also, the T8830C variant appears in current secondary listings and should not automatically be assumed identical to the original T8830. Verify the complete suffix and hardware revision before substitution.
