Product Overview

The 369B1841G5007 is a TC/RTD analog input module from GE. This module belongs to the MAI51 series. It reads signals from thermocouples and RTD sensors. The device supports both two-wire and three-wire RTD connections. A high-performance 32-bit embedded processor handles all data.

Technical Specifications

The 369B1841G5007 requires dual 24V DC power inputs with ±10% tolerance. The power supply supports 1:1 redundancy for high reliability. Power consumption is very low at less than 2W. Typical consumption runs at 1.8W. The operating voltage range is 21.6 to 26.4V DC.

This analog input module offers 16 input channels. Each channel accepts RTD or thermocouple signals. The module uses a 16-bit analog to digital converter. Eight channels share one ADC group. The measurement error stays at a maximum of 0.2%. This ensures accurate temperature readings for critical processes.

Supported Signal Ranges for 369B1841G5007

The 369B1841G5007 supports many RTD types. These include Pt10, Pt100, Cu100, and Cu50. Both two-wire and three-wire RTD connections work perfectly. The module also supports multiple thermocouple types. These include E, J, K, N, R, S, T, and B types. This wide range covers most industrial temperature applications.

Over-limit alarms trigger at ±10% using software detection. The module does not support over-limit alarms for ±10V input. Users can configure alarm settings through the software interface.

Isolation and Protection Features

The 369B1841G5007 provides strong electrical isolation. Channel to channel isolation is 250V AC. Channel to ground isolation is 500V AC.  This protects your control system from field wiring faults.

The common mode rejection ratio exceeds 120 dB. The differential mode rejection ratio exceeds 60 dB. The 369B1841G5007 resists electrical noise very effectively. This ensures stable readings in noisy industrial environments.

Communications and Connectivity

The 369B1841G5007 uses redundant high-speed intelligent serial buses. The communication rate is 1 Mbps for fast data transfer. A DB-9 female connector provides the bus interface. The terminal connector uses a single-row European-style terminal block. This block is removable for easy wiring replacement.

The terminal block accepts wire up to 2.5 mm². It supports dual-wire connections per terminal. The 369B1841G5007 mounts using standard screw fixation. This ensures a secure installation in your control cabinet.

LED Indicators

The 369B1841G5007 includes several useful LED indicators. A module run status LED shows operational condition. A communication status LED indicates bus activity. A fault alarm LED warns of any problems. These LEDs help with quick troubleshooting and diagnostics.

Environmental Specifications

The 369B1841G5007 operates from 0°C to 60°C ambient temperature. Humidity range is 10% to 90% without condensation. Vibration tolerance is 10 to 500 Hz. Acceleration must not exceed 10 m/s². The module works in standard industrial environments.

For air quality, dust particle size must exceed 0.5 µm. The maximum concentration is 18,000 particles per liter. The 369B1841G5007 meets these typical industrial conditions. The module carries CE certification with its system.

Dimensions and Standards

The 369B1841G5007 measures 209 mm high by 129.5 mm wide by 51 mm deep. The module meets several important standards. These include CFR 47 FCC Part 15: 2009 and ANSI C63.4-2003. It also complies with EN 61326-1: 2006 and CISPR 11: 2007. IEC 61000-4-2/3/4/5/6/8/11 standards are fully met.

Installation Guidelines

Mount the 369B1841G5007 using screws on a flat panel. Ensure the mounting surface is clean and secure. Connect dual 24V DC power supplies for 1:1 redundancy. Verify the voltage stays within 21.6 to 26.4V DC. Connect RTD or TC sensors to the 16 input channels. Use shielded twisted pair cables for all sensor wiring. Keep sensor wires away from high-voltage power cables. Remove the terminal block for easier wiring access. Push the block back firmly after completing all connections. Configure the software for your specific sensor types. Test each channel with a known temperature source before use.

Frequently Asked Questions (FAQ)

Q1: Can the 369B1841G5007 read both RTD and TC simultaneously?
Yes, each channel configures independently. The 369B1841G5007 mixes RTD and TC inputs on different channels.

Q2: What happens if one power supply fails?
The 1:1 redundant power keeps the module running. The 369B1841G5007 continues normal operation with one working supply.

Q3: How do I know if a channel is in alarm?
The software provides over-limit alarm detection at ±10%. The 369B1841G5007 sends this status to your control system.

Q4: Is this module suitable for high-vibration environments?
Yes, the module tolerates 10-500 Hz vibration. Acceleration up to 10 m/s² is acceptable for the 369B1841G5007.

Q5: What wire size fits the removable terminal block?
The terminal block accepts wires up to 2.5 mm². It also supports dual-wire connections for the 369B1841G5007.
