I/O modules

Product Overview

This terminal board connects RTD sensors directly to GE Mark VIe systems. You can mount GE IS200HSLAH1A IS200HSLAH1ADE inside standard industrial control cabinets. The unit accepts eight independent 3-wire RTD inputs simultaneously. Each channel provides constant current excitation for accurate resistance measurements.

Technical Specifications

Board Layout and Components

The PCB dedicates individual signal paths for each RTD channel. A precision current source provides 1 mA excitation to every sensor. Moreover, 108 discrete components handle lead wire resistance cancellation. The 3-wire design removes cable length errors automatically. Consequently, you get accurate temperature data regardless of wiring distance.

Installation Process

You can install GE IS200HSLAH1A IS200HSLAH1ADE on a standard 35 mm DIN rail. The 50-pin ribbon cable connects directly to the Mark VIe analog input card. Furthermore, each screw terminal accepts 16–26 AWG stranded or solid wire. Clearly marked channel labels show A, B, and B’ connections for each RTD.

Performance Advantages

This board maintains measurement accuracy within ±0.3°C for Pt100 sensors. Lead wire resistance cancellation works for cables up to 200 meters long. Therefore, remote sensor placement does not degrade reading quality. The passive design also draws minimal power from the system backplane.

Safety and Compliance

GE IS200HSLAH1A IS200HSLAH1ADE meets CE and RoHS industrial standards. The unit stores negligible electrical energy after power removal. Hence, technicians face no capacitor discharge risks during routine maintenance.
