Product Description

The 8C-TDILA is a high-density Digital Input (DI) module engineered for the Honeywell Experion PKS Series 8. It serves as the primary interface for 24 VDC discrete field signals, enabling the C300 controller to monitor real-time status from critical equipment such as limit switches, pushbuttons, and motor starter auxiliary contacts. The module ensures high signal integrity through robust galvanic isolation between field wiring and the control network.

Built with the Series 8 vertical form factor, the 8C-TDILA optimizes cabinet space and supports natural convection cooling. It features 32 independent channels, each with advanced electronic filtering to reject electromagnetic interference (EMI). The module also includes onboard diagnostics capable of detecting open-wire conditions, reducing troubleshooting time and improving system reliability in Distributed Control System (DCS) environments.

Application Scenarios

The 8C-TDILA is widely used in industries such as:

  • Oil and gas refining

  • Chemical processing

  • Power generation

Typical applications include:

  • Monitoring valve position feedback signals

  • Verifying emergency stop circuit status

  • Capturing high-speed discrete events for SOE recording

It is well-suited for applications requiring fast and reliable discrete signal acquisition with high diagnostic capability in Distributed Control Systems (DCS).

Frequently Asked Questions

Q: Does the 8C-TDILA support redundancy?
A: Yes. When installed on a redundant Series 8 Input Output Termination Assembly (IOTA), the 8C-TDILA can operate as a redundant pair, ensuring continuous signal acquisition and preventing data loss in the event of a hardware failure within the Honeywell Experion PKS Series 8.
