I/O modules

Product Overview

This terminal board interfaces RTD temperature sensors with GE Mark VIe controllers. You can mount GE IS200LSGIH1A IS200LSGIH1ABC directly inside standard industrial enclosures. The unit processes eight independent 3-wire RTD inputs simultaneously. Each channel delivers constant current excitation for stable resistance readings.

Technical Specifications

Board Layout and Components

The PCB isolates each RTD channel to prevent signal cross-talk. Precision resistors generate a stable 0.5 mA excitation for every sensor. Additionally, 104 discrete components perform lead resistance compensation automatically. The 3-wire design eliminates wire length errors without user calibration. Hence, you receive reliable temperature data from distant sensors.

Installation Process

You can install GE IS200LSGIH1A IS200LSGIH1ABC on a 35 mm DIN rail securely. The 50-pin ribbon cable connects directly to the Mark VIe analog input card. Furthermore, each screw terminal accepts 16–24 AWG copper wire. Labeled terminals clearly indicate A, B, and B’ connections for each RTD.

Performance Advantages

This board maintains Pt100 accuracy within ±0.25°C across the full range. Lead compensation works automatically for cables up to 150 meters long. Consequently, you can place sensors far from the control cabinet. The passive design also draws minimal backplane current.

Safety and Compliance

GE IS200LSGIH1A IS200LSGIH1ABC meets CE and RoHS industrial requirements. The unit stores no significant electrical charge after power-down. Therefore, technicians face no capacitor discharge hazards during maintenance.
