Square D CLE-202001 0-1 mA DC Output Signal Converter

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The Square D CLE-202001 Class 8410 Current Transducer converts standard 0–5 A AC current transformer inputs into proportional 0–1 mA DC analog signals for SCADA systems, analog meters, and PLC analog input cards. It plays a critical role in motor load monitoring, power distribution automation, and generator control panels across industrial plants.

Securing the CLE-202001 as New Surplus is a high-ROI risk mitigation strategy for aging facilities. Because Schneider Electric has discontinued legacy Class 8410 modules, purchasing verified New Surplus bypasses lengthy retrofit engineering while shielding your facility from the high failure rates of second-hand units. Maintaining 1–2 verified units on-site prevents low-probability, high-impact outages, preserving a low Total Cost of Ownership (TCO).

Installation & Configuration Guide

1.Stage 1: Pre-Installation (Prep & Safety):Prerequisites & LOTO.

Implement lock-out/tag-out procedures on the primary power feed and disconnect the current transformer (CT) secondary loop. Wear a grounded ESD wrist strap during handling. Photograph the terminal block connections and verify that the primary CT ratio provides a clean 0–5 A AC signal.

2.Stage 2: Removal:Safe Extraction.

Short-circuit the feeding current transformer’s secondary terminals prior to disconnection to prevent dangerous high-voltage spikes. Loosen the screw terminals on the legacy transducer, label all field wiring, unbolt the mounting chassis, and remove the unit carefully to avoid damaging terminal block threads.

3.Stage 3: Installation (Clone & Seat):Mechanical Mounting.

Mount the new Square D CLE-202001 transducer securely onto the panel backplate using appropriate mounting hardware. Wire the 0–5 A AC input conductors to Terminals 3 and 4, then wire the 0–1 mA DC output signal leads to Terminals 1 and 2 while maintaining correct DC polarity.

4.Stage 4: Power-On & Testing:Loop Verification.

Verify terminal tightness and remove the CT shorting block. Inject a test AC current (e.g., 2.5 A AC) into the input terminals and measure the DC output across Terminals 1 and 2 with a calibrated digital multimeter. Confirm the output reads exactly 0.50 mA DC (±0.5% scale linearity).

Firmware/Software Versions & Upgrade Notes

• Firmware Dependencies: As a purely analog solid-state signal transducer, the CLE-202001 does not utilize programmable firmware, flash memory, or microprocessor microcode.
• Compatibility Notes: The unit outputs a 0–1 mA DC current loop signal. Ensure your receiving PLC analog card or panel meter input channel is configured specifically for 0–1 mA DC scaling, rather than modern 4–20 mA or 0–10 V DC standards.
• Retrofit Warnings: If replacing a CLE-202001 with a modern 4–20 mA transducer, an active signal conditioner or input channel re-configuration is required. Swapping this module directly into a 4–20 mA loop without adjustment will result in inaccurate process variables and controller faults.

Frequently Asked Questions (FAQ)

Q: This product is a Brand New Surplus unit. Is it used, pulled, or refurbished?

A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. The terminal screws exhibit zero wear, the casing shows no mounting scuffs, and internal components maintain full structural integrity.

Q: Why buy New Surplus instead of taking a chance on a refurbished module?

A: Refurbished units carry hidden failures—most notably degraded internal capacitors and fatigued isolation transformers that look fine externally but fail under thermal stress. A 200 savings on a refurbished card vanishes instantly when a unexpected fault causes a 40,000 emergency shutdown. New Surplus gives you 10–15 years of operational life versus a 3–6 month lifespan on used hardware.

Q: Is the Square D Class 8410 still actively manufactured by the OEM?

A: No. The Class 8410 CLE series has reached End of Life (EOL) status. Sourcing New Surplus from verified global stock is the fastest way to drop in an exact replacement without spending thousands of dollars re-engineering panel layouts or re-programming PLC analog scaling blocks.

Q: Can I hot-swap this transducer while the primary circuit is under load?

A: Absolutely not. Disconnecting an active current transducer without shorting the CT secondary loop creates extremely high, open-circuit voltage levels. This poses an immediate electrical arc hazard and will destroy the terminal block. Always de-energize or short the CT loop prior to service.

Q: Does the require external auxiliary power supply connections?

A: No, the module is self-powered from the incoming 0–5 A AC signal loop. It derives its operating power directly from the measured input current to generate the isolated 0–1 mA DC proportional output.

Q: What warranty and quality verification backs this New Surplus unit?

A: Every unit passes complete dielectric isolation tests, input-to-output linearity checks, and continuous full-scale burn-in testing. We provide a full 1-year operational replacement warranty and supply complete QC inspection sheets with every order.
