Description

The GE IC697ALG230, also cataloged as the IC697ALG230 Analog Input Base Conversion Module, operates as a dedicated hardware component for multi-channel signal acquisition within Series 90-70 PLC systems.

Hardware Specifications

Backplane Bus Communication and Firmware Integration

The IC697ALG230 leverages high-speed backplane communication protocols to ensure deterministic data transfer between the module and the CPU. The architecture supports firmware flash compatibility, allowing for system-level synchronization across Series 90-70 racks. Deterministic network performance is maintained through strict timing windows for analog-to-digital data conversion cycles, minimizing jitter during signal processing. The module interface facilitates seamless integration with the system backplane, ensuring that I/O density scaling remains consistent even when operating with the maximum supported expansion configuration of up to 120 input channels.

Frequently Asked Questions

Q: Does the IC697ALG230 support hot-swap functionality?

A: No, the module requires the PLC rack power to be cycled or the specific slot power to be isolated before physical removal or insertion to prevent damage to the backplane pins.

Q: What is the maximum load for the expansion capability of this module?

A: The base module supports up to seven expansion modules, allowing a total of 120 input channels when properly configured and addressed within the PLC memory map.

Q: How is the signal integrity maintained during differential input processing?

A: Each channel employs individual low-pass filters to mitigate common-mode noise, and opto-isolation provides electrical decoupling from the PLC backplane to eliminate ground loops.

Field Installation Guidelines

• Ensure the backplane is de-energized before mounting the module into the designated slot.
• Secure the module using the integrated locking mechanisms to ensure a stable connection with the backplane bus.
• Utilize the 40-terminal removable connector block for field wiring; ensure all signal wires are shielded and that the shields are terminated at a single common ground point to reduce EMI.
• Verify that the input voltage or current signals match the programmed configuration (voltage or current mode) prior to applying power to the field circuits.
• Maintain a minimum clearance of 5 cm around the module housing to allow for adequate convection cooling during operation.
