GE IC670ALG310-JA

Description

Product Overview

The GE IC670ALG310-JA is a specialized analog input module designed for the GE Fanuc Series 90-30 PLC and VersaMax I/O systems. This module serves as a high-density interface for connecting voltage or current signals from field transmitters, providing the PLC with critical data for process monitoring and control. The GE IC670ALG310-JA is known for its compact design and reliable performance in industrial environments.

Key Product Parameters

• Product Type: Analog Input Module

• Compatible Systems: GE Series 90-30 PLC (with appropriate bus interface unit) and VersaMax I/O racks.

• Channels: 16 single-ended input channels.

• Input Signal Types: Configurable per channel for either 0-10V DC voltage or 0-20mA / 4-20mA current input.

• Resolution: 12-bit analog-to-digital conversion.

• Input Impedance: High impedance for voltage inputs (>1MΩ), 250Ω nominal for current inputs.

• Isolation: Channel-to-bus isolation (500VAC), but channels are not isolated from each other (common ground).

• Update Time: Varies based on the number of active channels.

• Connection: Uses a removable terminal block connector for field wiring.

Advantages and Core Features

The primary advantage of the GE IC670ALG310-JA is its high channel density in a single module slot, offering a cost-effective solution for applications requiring many analog points. Its per-channel configurability (voltage or current via DIP switches or software, depending on the series) provides significant flexibility for system design and reduces the need for multiple module types. The module is designed for easy integration and features diagnostics such as open wire detection for current inputs. The reliability of the IC670ALG310-JA makes it a staple for standard analog data acquisition tasks.

Application Scenarios

This module is widely used in processes requiring monitoring of multiple analog variables:

• Environmental Monitoring: Measuring multiple temperature, pressure, or flow points in HVAC and building management systems.

• Water Treatment: Monitoring pH, chlorine residual, tank levels, and flow rates across various stages of a treatment plant.

• Packaging & Material Handling: Reading analog signals from weight scales, tension sensors, or analog positioning devices on conveyors.

• Machine Monitoring: Collecting data from multiple pressure transducers or temperature sensors on a production machine.

• Energy Management: Sub-metering electrical loads by measuring 4-20mA signals from power transducers.

Comparison with Competing Products

Competing products include analog input modules from Allen-Bradley (Compact I/O, e.g., 1769-IF8) and Siemens (ET 200S, e.g., 6ES7134-4GB01-0AB0). The GE IC670ALG310-JA distinguishes itself with its high channel count (16) in a compact form factor, often providing a lower cost per channel. However, its non-isolated channel design may be a limitation compared to modules offering channel-to-channel isolation in electrically noisy environments or where ground loops are a concern. It represents a practical, workhorse solution within the GE ecosystem.

Selection Guide and Important Notes

Selecting the GE IC670ALG310-JA requires verifying compatibility with the specific 90-30 CPU/VersaMax bus interface and ensuring the application does not require isolated channels.

Important Precautions:

• Signal Common: All 16 channels share a common return (AGND). This is unsuitable for signals from devices with different ground potentials, as it can create ground loops.

• Configuration: The input type (voltage or current) for each channel group must be correctly set using the module’s DIP switches or configured in the PLC hardware configuration software.

• Noise Immunity: In environments with significant electrical noise, using shielded twisted-pair cables and proper grounding practices is essential due to the lack of channel-to-channel isolation.

• Power Budget: Ensure the PLC rack or VersaMax power supply has sufficient capacity to power the IC670ALG310-JA and all other installed modules.

• Open Wire Detection: This feature only works for current input channels (4-20mA) when the input is configured correctly.
