FC-TSDI-16115: Product OverviewThe FC-TSDI-16115 is a 16-channel digital input module engineered for Honeywell’s ControlEdge™ C300 distributed control system (DCS) and safety instrumented systems (SIS). It serves as a specialized interface for acquiring temperature signals from field-mounted thermocouples and RTD sensors, converting raw millivolt (thermocouple) or resistance (RTD) inputs into calibrated engineering units (e.g., °C, °F) for controller processing. Its primary role is to enable precise temperature monitoring of critical process variables—such as reactor temperatures, furnace zones, or pipeline thermal profiles—in industries where temperature control directly impacts safety, product quality, and energy efficiency.Functionally, the module processes inputs from 16 independent channels, each configurable for thermocouple types (J, K, T, E, N, R, S, B) or RTD types (Pt100, Pt1000, 2/3/4-wire). It employs galvanic isolation (2500VAC) to prevent ground loops and electromagnetic interference (EMI) from corrupting low-level signals, a critical feature for accurate temperature measurement in electrically noisy environments. As part of the ControlEdge C300 family, the FC-TSDI-16115 integrates with the platform’s high-speed I/O link, hot-swappable architecture, and unified engineering tools (ControlEdge Builder), simplifying configuration and maintenance. This design aligns with compliance to IEC 61508 (SIL 2) and standards like ASME PTC 19.3 (temperature measurement) or API 556 (refinery instrumentation).

Honeywell FC-TSDI-16115
Core Features & Customer ValueHigh-Channel Density Reduces Cabinet Footprint: With 16 input channels per module, the FC-TSDI-16115 minimizes the number of I/O modules required in a control cabinet. For engineers designing systems with extensive temperature sensing (e.g., a refinery’s crude distillation column with 12 thermocouples and 4 RTDs), this cuts cabinet space by 50% compared to 8-channel alternatives, simplifying wiring and reducing material costs.Galvanic Isolation Ensures Measurement Accuracy: The 2500VAC isolation between channels and the C300 bus prevents EMI from industrial equipment (e.g., motors, drives) from distorting low-level thermocouple/RTD signals. In a chemical plant’s exothermic reactor, this ensures accurate temperature readings—critical for preventing runaway reactions—even near high-power agitators.Configurable Input Types Support Diverse Sensors: Each channel can be independently set for 8 thermocouple types or 2 RTD types (with 2/3/4-wire configuration), allowing engineers to standardize on a single module for mixed sensor installations. For a power plant upgrading its boiler temperature monitoring, this eliminates the need for separate modules for different sensor families.Comprehensive Diagnostics Simplify Maintenance: Built-in diagnostics monitor for open/short circuits (sensor leads), CJC faults, and overrange conditions. Faults are reported to the C300 controller via I/O link, with LED indicators on the faceplate for quick visual identification. For maintenance teams, this reduces troubleshooting time from hours to minutes—e.g., identifying a broken thermocouple wire in a furnace zone without invasive testing.Hot-Swappable Design Minimizes Downtime: The module can be replaced while the system remains powered, essential for continuous processes like oil refining or chemical production. Technicians simply remove the faulty unit and insert a new one; the C300 controller automatically reloads configuration data via I/O link. This eliminates scheduled shutdowns for module replacement, saving thousands in lost production per incident.SIL 2 Certification for Safety-Critical Applications: When integrated into a Honeywell Safety Manager SIS, the FC-TSDI-16115 meets SIL 2 requirements (IEC 61508), enabling its use in safety functions like reactor overtemperature shutdown or furnace flameout protection. Its fault-tolerant design (hardware fault tolerance ≥1) reduces the probability of dangerous failures, aligning with audit requirements for regulated industries.Typical ApplicationsThe FC-TSDI-16115 is deployed in systems requiring reliable temperature signal acquisition. In a petroleum refinery’s catalytic reformer, it connects 16 thermocouples monitoring reactor tube temperatures. The module’s ±0.1% accuracy ensures optimal catalyst activity, while diagnostics alert staff to a failing thermocouple before temperature deviations degrade product yield.At a chemical plant’s polymerization reactor, the FC-TSDI-16115 interfaces with 12 RTD sensors (3-wire Pt100) measuring jacket coolant temperature and 4 thermocouples (K-type) monitoring reaction mixture temperature. Its 2500VAC isolation prevents EMI from agitators from causing false readings, ensuring precise control of reaction kinetics. Hot-swap capability allows maintenance during planned turnarounds without halting production.In a municipal water treatment plant, the module monitors 8 RTD sensors (Pt1000) in filtration basin pipes and 8 thermocouples (J-type) in sludge digesters. The C300 controller uses these inputs to adjust heating/cooling systems, with diagnostics flagging a faulty RTD before effluent temperature violates EPA limits.
