Honeywell Triconex 3301S2 – 8-Channel Temperature Input Module for Thermocouple and RTD Sensors

In stock

Product Introduction:
The Triconex 3301S2 is an 8-channel temperature input module designed to read signals directly from thermocouple and RTD (Resistance Temperature Detector) sensors without requiring external signal conditioners. The “3301” identifies it as a temperature input module, while the “S2” suffix denotes the Series 2, S2 revision, which offers improved accuracy, faster scan times, and enhanced diagnostics compared to the original Series 1. This module provides 8 independent input channels, each capable of reading any standard thermocouple type (J, K, T, E, N, R, S, B) or RTD type (Pt100, Pt1000, Cu10, Ni120). The module performs cold junction compensation internally, eliminating the need for external cold junction reference junctions.

Functional Features:
Direct Sensor Connection: No external signal conditioners or transmitters required; connects directly to thermocouples and RTDs.
Built-In Cold Junction Compensation: Automatically compensates for the temperature at the terminal block, eliminating a common source of error.
Per-Channel Configuration: Each channel independently configurable for sensor type, range, and filtering.
Burnout Detection: Automatically detects a broken thermocouple or RTD wire and alarms the operator immediately.
Fast Scanning: 250ms scan time captures fast temperature transients that standard modules would miss.
LED Indicators: Per-channel LEDs show sensor status (green for normal, red for fault).

Application Scenarios:
Furnace Temperature Monitoring: Reads thermocouples directly from gas turbines, boilers, and furnaces for overtemperature protection.
Reactor Temperature Monitoring: Monitors RTDs on chemical reactors for runaway reaction detection.
Bearing Temperature Monitoring: Reads RTDs on turbine and compressor bearings for hot-bearing trips.
Exhaust Gas Temperature: Monitors turbine exhaust temperature (TET) for heat rate optimization and hot-end protection.
Process Temperature Monitoring: Reads temperature sensors on heat exchangers, distillation columns, and storage tanks.
