Honeywell TC-IXR061 RTD Input Module 6-Point

Honeywell TC-IXR061 Isolated RTD Input Module

Product Introduction

The Honeywell TC-IXR061 is a 6-point RTD input module engineered for accurate resistance temperature measurement in industrial control systems. Each of its six channels is galvanically isolated, which prevents ground loops and protects signals in demanding plant environments. Specifically, the module accepts four signal input ranges: 1-487Ω, 2-1000Ω, 4-2000Ω, and 8-4020Ω. Additionally, it supports a wide variety of platinum, nickel, and copper sensors, giving engineers flexibility across different temperature sensing applications. The TC-IXR061 delivers 16-bit resolution on every range with 0.1% full-scale accuracy at 25°C. Furthermore, its 120 dB common mode rejection and robust RFI immunity keep readings stable in electrically noisy cabinets. This isolated RTD module suits process monitoring, custody transfer, and other precision temperature loops.

Isolation and Mechanical Parameters

Channel-to-channel isolation is 100% tested at 2546 VDC for 1 second. The user-to-system path carries the same 2546 VDC test rating. Therefore, the module protects personnel and equipment even when field wiring faults occur. The TC-IXR061 connects through a TC-TBNH 20-position terminal block for secure field termination. Its compact housing fits standard Honeywell I/O racks, and the 4.3 W maximum dissipation allows dense panel layouts with normal cabinet ventilation. Backplane current figures appear in the Honeywell module power consumption data on page 46 of the system manual.

Installation Guide

Installing the Honeywell TC-IXR061 follows a straightforward sequence. First, mount the module in a compatible Honeywell I/O rack with adequate ventilation for 4.3 W dissipation. Next, attach the TC-TBNH 20-position terminal block to the module. Then, wire each RTD sensor using three-wire or four-wire connections to match the chosen input range. Additionally, select the correct sensor type and range in the configuration software before commissioning. Keep field wiring shielded to preserve the 120 dB common mode rejection rating. The isolated channels tolerate independent ground potentials, so verify each channel's reference before applying power. Finally, confirm backplane current against the system power budget. Always follow local electrical codes and Honeywell installation documentation.

FAQ

Q1: What sensor types does the TC-IXR061 support?
A: The module supports 100, 200, 500, and 1000Ω platinum sensors with α = 0.00385 or 0.003916. Furthermore, it accepts 120Ω nickel, 100/120/200/500Ω nickel, and 10Ω copper sensors.

Q2: Are the input channels isolated from each other?
A: Yes, all six channels are galvanically isolated. Specifically, channel-to-channel isolation is 100% tested at 2546 VDC for 1 second, and the user-to-system path carries the same rating.

Q3: What is the resolution of this RTD module?
A: The TC-IXR061 delivers 16 bits across each input range. Moreover, resolution per bit ranges from 7.7 milliohms on the 487Ω range to 60 milliohms on the 4020Ω range.

Q4: How does the module report a broken sensor wire?
A: Open wire detection reports an out-of-range reading in less than 5 seconds. Therefore, the control system can trigger an alarm or force a safe state.

Q5: What shipping methods are available?
A: We ship the Honeywell TC-IXR061 via Fedex, UPS, and DHL. Besides, every order includes anti-static packaging to protect sensitive electronics during transit.
