---

### **Pros of the IC660ELB901**

1. **High Reliability and Durability**

- Built to industrial standards, this module is designed for harsh environments, including temperature fluctuations, vibration, and electrical noise.

- GE Fanuc (now part of Emerson) has a long history of manufacturing robust automation components, ensuring long-term performance.

2. **Isolated Inputs for Noise Immunity**

- Each of the 16 inputs is **optically isolated**, protecting the PLC from voltage spikes, ground loops, and electromagnetic interference (EMI).

- This isolation enhances system stability, especially in applications with noisy signals (e.g., motor starters, relays, or high-voltage equipment).

3. **Wide Input Voltage Range**

- Supports **24V DC, 115V AC, or 230V AC** inputs, making it versatile for different field devices (sensors, switches, or relays).

- Compatible with a variety of standard industrial signals without requiring additional conversion.

4. **Backward and Forward Compatibility**

- Works seamlessly with **IC660 series PLCs**, including older models, ensuring ease of integration in existing systems.

- GE Fanuc provides firmware updates and support for extended periods, reducing long-term obsolescence risks.

5. **Easy Installation and Wiring**

- Standard **terminal block connections** simplify wiring, reducing installation time and potential errors.

- The module s compact size (part of the **IC660 series**) allows for efficient rack mounting in control panels.

6. **Diagnostic Capabilities**

- GE Fanuc PLCs offer **built-in diagnostics** for input modules, helping identify faults such as open circuits, short circuits, or voltage level issues.

- Fault codes can be read via the PLC s programming software (e.g., **GE Proficy Machine Edition** or **RSLogix 5000**), aiding in troubleshooting.

7. **Support for High-Speed Inputs**

- Some configurations of the IC660 series support **high-speed input scanning** (up to 100 s resolution), useful for applications requiring precise timing (e.g., motion control, conveyor systems).

8. **Cost-Effective for Medium-Sized Applications**

- While not the cheapest module on the market, its **lifespan, reliability, and compatibility** often justify the cost in industrial automation projects.

- Avoids the need for additional signal conditioning hardware, reducing overall system complexity.

---

### **Cons of the IC660ELB901**

1. **Limited Availability and Obsolescence Concerns**

- GE Fanuc s automation business has undergone restructuring, leading to **reduced support and stock availability** for older models like the IC660 series.

- Some distributors may carry limited inventory, potentially causing delays in replacement or repair.

2. **Higher Upfront Cost Compared to Alternatives**

- Newer or competing PLC systems (e.g., **Siemens, Allen-Bradley (Rockwell), or Mitsubishi**) may offer similar modules at a lower price.

- The IC660 series is **not as widely supported** as more modern platforms, which can impact long-term cost efficiency.

3. **Software Dependency on GE/Fanuc Ecosystem**

- Programming and configuration require **GE s proprietary software** (e.g., **RSLogix 5000, Proficy, or Machine Edition**), which may not be as user-friendly as alternatives like **Studio 5000 (Rockwell) or CodeSys**.

- Training engineers on GE s software can be more challenging than on more widely adopted platforms.

4. **No Built-in Ethernet or Advanced Communication Protocols**

- Unlike newer PLCs, the IC660 series lacks **integrated Ethernet/IP, Modbus TCP, or PROFINET** support out of the box.

- Additional **communication modules** (e.g., **IC697**) may be required for modern network integration, increasing system complexity.

5. **Potential for Higher Maintenance Costs**

- While reliable, the **lack of modern diagnostics and remote monitoring tools** can make maintenance more time-consuming.

- GE Fanuc s customer support has been **consolidated under Emerson**, which may result in slower response times compared to dedicated automation vendors.

6. **Physical Size and Rack Space Requirements**

- The IC660 series occupies **more rack space** than some modern compact PLCs (e.g., **Allen-Bradley CompactLogix**).

- This can be a limitation in space-constrained control panels.

7. **Limited Expansion Capabilities**

- The IC660 series has **fewer high-speed or advanced I/O options** compared to newer architectures, which may restrict scalability for complex automation tasks.

### **Conclusion**

The **GE Fanuc IC660ELB901** remains a **reliable, high-quality digital input module** well-suited for **industrial applications requiring isolated, noise-resistant inputs**. Its **durability, wide voltage compatibility, and diagnostic features** make it a strong choice for **legacy systems or projects where GE Fanuc compatibility is non-negotiable**.

However, **obsolescence risks, higher costs, and software limitations** may make it less ideal for **new installations or applications requiring modern communication protocols**. If **long-term support, ease of programming, or cost efficiency** are priorities, newer PLC platforms (e.g., **Rockwell Automation, Siemens, or Mitsubishi**) may offer better alternatives.

---

### **Recommendation**

- **Buy the IC660ELB901 if:**

- You are **maintaining or upgrading an existing GE Fanuc IC660 system**.

- Your application **requires isolated inputs in a noisy environment** (e.g., motor control, heavy machinery).

- You have **existing GE Fanuc expertise** and can leverage their software ecosystem.

- You can **source spare parts reliably** (check with authorized distributors like **AutomationDirect, Grainger, or Emerson s resale channels**).

- **Consider alternatives if:**

- You are **starting a new project** and want **modern PLCs with better support and communication options**.

- You need **Ethernet/IP, Modbus, or PROFINET** for network integration.

- **Cost efficiency and long-term availability** are critical (e.g., **Allen-Bradley 1761-IA16 or Siemens ET 200SP** may be better choices).

- Your team is **more familiar with Rockwell, Siemens, or Mitsubishi** programming environments.

For **new builds**, evaluating **Rockwell Automation s CompactLogix, Siemens SIMATIC S7-1200, or Mitsubishi s FX series** could provide a better balance of **cost, support, and future-proofing**. However, if **compatibility with an existing GE Fanuc system** is mandatory, the **IC660ELB901 remains a solid, proven solution**.
