System Architecture & Signal Flow
The 369B1848G5001 operates within GE’s distributed I/O architecture as follows:
- RTD Sensor Input — PT100/PT1000 sensors connect via 3-wire shielded cable to the module’s terminal block
- Signal Conditioning — Onboard analog front-end applies excitation current, measures voltage drop, and compensates for lead resistance
- A/D Conversion — High-resolution ADC converts the conditioned analog signal to a digital temperature value
- Backplane Communication — Digitized data is transmitted over the GE Mark series I/O bus to the main controller (UCCE/UCCA/UCSB)
- HMI & SCADA Integration — Temperature values appear in GE Toolbox, Cimplicity HMI, or third-party SCADA via OPC-DA/UA gateway
Sourcing & Quality Verification

Technical FAQ
Q: Is the 369B1848G5001 compatible with GE Mark VI MOOG I/O racks?
A: Yes. The module is designed for GE’s standard Mark VI I/O rack form factor and interfaces with MOOG-sourced rack assemblies used in later Mark VI configurations.
Q: Can this module accept 4-wire RTD inputs?
A: The 369B1848G5001 is optimized for 3-wire PT100/PT1000 configurations. 4-wire RTDs can be connected using 3 of the 4 leads, though the additional accuracy benefit of the 4th wire will not be utilized.
Q: What is the maximum cable length supported between the RTD sensor and this module?
A: GE recommends a maximum of 300 meters for 3-wire PT100 configurations using 1.5 mm² shielded cable. Longer runs require lead resistance compensation verification.
Q: Does Konmask provide calibration certificates with this module?
A: Yes. All units are supplied with a factory calibration certificate traceable to IEC 60751 / NIST standards. Custom recalibration services are available upon request.
Q: What is the lead time for the 369B1848G5001?
A: In-stock units ship within 3–5 business days. For out-of-stock scenarios, lead time is typically 4–8 weeks depending on sourcing channel. Contact us for real-time availability.
Q: Is this module RoHS compliant?
A: Units manufactured after 2011 comply with RoHS Directive 2011/65/EU. Please specify your compliance requirement when placing an order so we can confirm the manufacturing batch.
