GE IC200ALG620 RTD Input Module 4-Channel 16-Bit VersaMax

Product Introduction

The IC200ALG620 is a high-precision RTD input module from the GE Fanuc VersaMax series. This module provides four dedicated input channels for Resistance Temperature Detector sensors. It supports 3-wire and 4-wire RTD configurations. The module accepts a broad range of sensor types, including Platinum 25, 100, and 1000 ohm. It also supports Copper 10, 50, and 100 ohm, Nickel 100 and 120 ohm, and Nickel/Iron 604 ohm sensors. Furthermore, the module can directly measure resistance values from 0-500 Ohms and 0-3000 Ohms. Each channel features a dedicated analog-to-digital converter with 16-bit resolution. Therefore, this module delivers accurate and reliable temperature measurements for demanding industrial applications.

Key Technical Specifications

The IC200ALG620 offers exceptional measurement accuracy. At 25°C, accuracy is +/-0.15% for resistance measurement. Similarly, temperature measurement accuracy is +/-0.15% for RTD mode. The channel update rate is approximately 210 ms per channel at 60 Hz. Meanwhile, the update rate is approximately 230 ms per channel at 50 Hz. For digital resolution, the module provides 15 bits plus sign. The maximum lead resistance is 5 ohms per lead. Additionally, temperature sensitivity from 0°C to 60°C is +/-0.004% of reading. The voltage drift is +/-1.5µV per °C referred to input.

Power Requirements and Isolation

The IC200ALG620 draws 125 mA maximum from the 5 VDC backplane output. It also draws 125 mA from the 3.3 VDC bus output. For isolation, the module provides 250 VAC between user input and logic. It also offers 1500 VAC for 60 seconds between user input and frame ground. This robust isolation protects against electrical noise. It also safeguards connected PLC systems from voltage surges.

Diagnostic and Monitoring Features

Each input channel on the IC200ALG620 includes comprehensive diagnostics. The module detects open RTD, input short, underrange, and overrange conditions. It also identifies wiring faults, non-volatile memory storage faults, and high/low alarms. These fault and alarm conditions are reported to the host PLC for integration. Therefore, operators can quickly identify and address sensor issues. This reduces downtime and improves system reliability.

LED Indicators and Status

The front panel of the IC200ALG620 features two LED indicators. The FLD PWR LED shows that backplane power and field power are present. The OK LED signals normal module operation when lit green. When the LED illuminates amber, a diagnostics error is present. Moreover, the LED flashes green when the module is updating or in boot mode. These visual indicators enable rapid troubleshooting. Consequently, maintenance personnel can quickly assess module status.

Supported RTD Sensor Types

The IC200ALG620 supports an extensive range of RTD sensors. Platinum sensors include 25, 100, and 1000 ohm types. Copper sensors include 10, 50, and 100 ohm types. Nickel sensors include 100 and 120 ohm types. The module also supports Nickel/Iron 604 ohm sensors. For resistance-only measurements, the module accepts 0-500 Ohms and 0-3000 Ohms. This wide compatibility makes the IC200ALG620 suitable for diverse temperature applications.

Mounting and Environmental Guidelines

The IC200ALG620 installs easily in the VersaMax I/O rack. Proper grounding is essential during installation to prevent electrical damage. The operating temperature range is 0°C to 60°C ambient. The module should be installed in a clean environment. It operates at frequencies of 50-60 Hertz. The common mode rejection ratio is 120 dB at 50-60 Hz with 100% span. The normal mode rejection is 60 dB at the same frequency. Therefore, the module offers excellent noise rejection for stable measurements.
