369B1841G5007 GE MAI51 TC/RTD Module | 369B1841G5007 Card

GE 369B1841G5007 Engineering Overview

• The 369B1841G5007 features a 32-bit RISC processor with 16-bit ADC resolution across dual 8-channel acquisition banks.
• Supports multiple RTD curves (Pt10, Pt100, Cu50, Cu100) and TC types (E, J, K, N, R, S, T, B).
• Integrated dual-redundant 24V DC power inputs prevent card shutdown upon primary power feed loss.
• Communication operates over a 1Mbps high-speed redundant intelligent serial bus via DB-9 female connectors.
• Galvanic isolation rated at 1500VAC channel-to-system and 250VAC channel-to-channel protects control system electronics.
• Removable single-row European terminal blocks accept dual 2.5mm² wiring for fast field swap-outs.

Frequently Asked Questions (FAQ)

• Q1: What sensor inputs does the 369B1841G5007 analog input card support?
• A: The 369B1841G5007 natively reads 2-wire/3-wire RTDs (Pt10, Pt100, Cu50, Cu100) and TC types (E, J, K, N, R, S, T, B).
• Q2: Does software judgment alarm trigger on ±10V inputs?
• A: No, over-limit alarm logic operates on temperature sensor inputs; ±10V voltage inputs bypass the software limit alarm function.
• Q3: What engineering steps are necessary when replacing an older MAI51 module?
• A: Unplug the removable European terminal block, swap the hardware unit, and confirm sensor curve selection matches host database scaling.
• Q4: How do I choose between replacing the 369B1841G5007 or inspecting field wiring?
• A: If an entire 8-channel bank shows erratic readings simultaneously, inspect power/grounding; if a single isolated channel fails, replace the 369B1841G5007.
• Q5: What power supply parameters are required for the redundant power terminals?
• A: Provide dual independent 24V DC lines (21.6 to 26.4V DC) with a total module power consumption under 2W.
