Product Overview

The IC695ALG412 is a high-precision strain gauge analog input module for the PACSystems RX3i series. It provides the interface between bridge-based sensors—such as load cells, pressure transducers, and torque sensors—and the PLC backplane. Supplied as 100% Brand New, this module ensures maximum signal integrity for critical weighing, force, and tension applications.

Technical Specifications

Engineering Advantages

• Superior Resolution: The 24-bit ADC captures minute voltage changes, enabling detection of extremely subtle variations in weight or force.

• On-Board Excitation: Provides stable excitation voltage directly to sensors, eliminating external power sources and simplifying wiring.

• Environmental Noise Rejection: Channel isolation and filtering protect delicate millivolt signals from industrial electrical interference.

• Automatic Calibration: Software-driven zero and span calibration compensates for lead-wire resistance and sensor drift, maintaining long-term accuracy without manual adjustments.

FAQs

Does this module support both 4-wire and 6-wire load cells?
Yes. It supports 6-wire configurations, using sense lines to compensate for voltage drops over long cables.

Can I mix different sensor types on the four channels?
Yes. Each channel is independently configurable for input range and update rate, allowing diverse sensor arrays on a single module.

Does the module detect sensor failure?
Yes. Built-in diagnostics trigger alarms for open circuits, short circuits, or excitation power loss to prevent false readings.

Is this module compatible with legacy Series 90-30 racks?
No. It requires the RX3i Universal Backplane’s high-speed PCI bus and does not operate in Series 90-30 expansion racks.
