GE Fanuc IC697VAL318 8-Channel Analog Output Board

IC697VAL318 Isolated 8-Channel 12-bit Analog Output Board

Product Introduction

The IC697VAL318 analog output module belongs to GE Fanuc’s Series 90-70 PLC family. This isolated board delivers eight channels of 12-bit analog output signals. Each channel generates a standard 4-20mA current signal for precise process control. The module includes a removable terminal block that simplifies field wiring and maintenance. Additionally, it requires no separate cable for connection, reducing installation complexity. This output board suits applications like valve positioning, variable speed drives, and actuator control.

Technical Specifications

The IC697VAL318 provides eight fully isolated analog output channels. Each channel offers 12-bit resolution for fine-grained signal accuracy. The output range is fixed at 4 to 20 milliamps, matching common industrial instrumentation standards. Isolation between channels and the backplane enhances noise immunity and protects the main CPU. The module uses a removable terminal block for all field wiring terminations. Specifically, this terminal block supports twisted-pair or shielded cables for optimal signal integrity. The board draws power directly from the Series 90-70 backplane. Its typical update rate ensures responsive control loops. Meanwhile, the module performs built-in diagnostics to detect open-wire conditions. Furthermore, the design includes transient protection for harsh industrial environments. This output board works seamlessly with the Series 90-70 CPU and remote I/O scanners.

Mechanical and Environmental Parameters

This analog output board weighs approximately 1.5 pounds (0.7 kg). It occupies a single slot in a Series 90-70 rack. The operating temperature range spans 0 to 60 degrees Celsius. Storage temperatures extend from -40 to 85 degrees Celsius. Relative humidity tolerance reaches 5% to 95% without condensation. Moreover, the module withstands vibration and shock per industrial standards. Its compact form factor leaves room for other I/O modules in the chassis. The front panel features LED indicators for each channel’s status.

Installation Guidelines

First, power down the Series 90-70 rack before inserting the IC697VAL318. Slide the module firmly into the chosen slot until the locking mechanism engages. Next, wire each output channel to the removable terminal block. Match the signal and return connections as per the terminal labeling. For instance, use shielded twisted-pair cables to minimize electromagnetic interference. After wiring, plug the terminal block into the module’s front connector. Ensure all wires are securely fastened to avoid loose connections. Then, apply power and verify the LEDs indicate normal operation. Finally, configure the output ranges and scaling within the PLC logic using the programming software.

Frequently Asked Questions (FAQ)

1. Q: Does the IC697VAL318 support voltage outputs like 0-10V?
A: No, this model specifically provides 4-20mA current outputs only. For voltage outputs, consider other analog modules in the Series 90-70 range.

2. Q: Is external power supply needed for the output signals?
A: No, the IC697VAL318 draws loop power from the backplane. The 4-20mA signals are self-powered by the module itself.

3. Q: How do I connect field devices to this module?
A: Simply wire your actuators or instruments to the removable terminal block. Then insert the block into the module’s front connector without any extra cable.

4. Q: Can I replace the terminal block while the system is running?
A: We do not recommend hot-swapping the terminal block. Always power down the rack before removing or inserting the terminal block to prevent damage.

5. Q: What diagnostic features does this output board include?
A: The IC697VAL318 detects open-circuit conditions on each channel. Additionally, the status LEDs signal individual channel faults for quick troubleshooting.
