Product Overview

The Honeywell 8C-TDILA1 (also identified by part number 51307141-175) acts as the physical connection interface for the Experion PKS C300 Series 8 hardware. This Digital Input Termination Assembly (IOTA) facilitates the routing of discrete signals from field-side equipment—such as limit switches, push buttons, and dry contacts—directly to the 8C-PDILA1 input module. By centralizing 32 channels of signal acquisition, the 8C-TDILA1 optimizes cabinet space and simplifies field wiring. We supply this unit as 100% Brand New and Original, ensuring seamless integration into critical DCS environments including petrochemical, power generation, and advanced manufacturing facilities.

Technical Specifications

Engineering Advantages

• Optimized Field Termination: The 8C-TDILA1 provides a structured termination point for 32 separate digital inputs. This high-density layout reduces the footprint required within the control room and minimizes the complexity of cable management.

• Universal Input Flexibility: The hardware supports both PNP and NPN configurations. This versatility allows engineers to integrate a wide variety of third-party field devices, including dry contacts, without requiring additional signal conditioning modules.

• Extreme Environmental Resilience: Engineered for performance in non-climate-controlled zones, the assembly operates within a temperature range of -40°C to +75°C. This robustness ensures consistent signal monitoring in outdoor enclosures or high-heat process areas.

• Enhanced Signal Safety: Built-in galvanic isolation shields the C300 controller from field-side electrical noise and surges. This protection prevents transient faults at the switch level from propagating to the core DCS backplane, maintaining system uptime.

• Rapid Hardware Integration: The Series 8 9-inch profile and DIN rail mounting capability allow for fast installation. The IOTA design facilitates a direct, secure interface with the 8C-PDILA1 input module, ensuring reliable data transfer across the system bus.

FAQs

• Is the 8C-TDILA1 compatible with redundant configurations?

  No, this specific model (8C-TDILA1) is a simplex (non-redundant) termination assembly. For high-availability applications requiring redundancy, a different IOTA part number is necessary.

• Does this part number include the electronic input module?

  No. The 8C-TDILA1 is the Termination Assembly (IOTA) only. You must pair it with the 8C-PDILA1 electronic input module to create a functional digital input circuit.

• Can I use this IOTA with older Honeywell Series A or Series C hardware?

  The 8C-TDILA1 belongs strictly to the Series 8 / Experion PKS C300 platform. It is not physically or electrically compatible with legacy Honeywell Series A or C termination systems.

• What is the condition of this unit and its shipping time?
