Eaton CS-TX3-3.81X2.54-64TW High-Density 64-Pin Control Card - Industrial Automation Signal Processing Module

1. Product Overview

The Eaton CS-TX3 series represents a lineup of high-density industrial control interface cards engineered for centralized signal routing, data acquisition, and logic expansion within low-voltage automation systems. The CS-TX3-3.81X2.54-64TW is the flagship 64-channel variant, optimized for high I/O count machinery, motor control centers, packaging lines, and process control panels.
This control card features a compact PCB layout with a dual-row terminal pitch of 3.81mm × 2.54mm, delivering 64 independent signal terminals to accommodate digital inputs, digital outputs, analog signals, and communication wiring. It acts as a bridge between Eaton PLCs, XV400 HMIs, MP series motor protection relays and field-level sensors/actuators, simplifying cabinet wiring, reducing cable clutter and improving signal stability in harsh industrial environments.
Designed for DIN rail panel mounting, the CS-TX3-3.81X2.54-64TW integrates Eaton’s proprietary anti-interference circuit design, built-in surge suppression and reinforced insulation, ensuring long-term stable operation under vibration, wide temperature fluctuations and electromagnetic interference common in production workshops.

Model Code Breakdown

  • CS-TX3: Core product series – High-density industrial signal control card

  • 3.81×2.54: Dual terminal pitch dimension (3.81mm horizontal / 2.54mm vertical pin spacing)

  • 64: Total 64 signal contact points on board

  • TW: Industrial tin-plated wide-temperature terminal version, anti-oxidation, suitable for long-term continuous operation

2. Core Product Features

2.1 High-Density Terminal Layout

  • 64 independent signal channels on a single PCB, dual-row 3.81×2.54mm pitch terminals

  • Compact footprint saves cabinet space compared to multiple small breakout cards.

  • Tin-plated TW terminals provide excellent conductivity, anti-corrosion, and anti-oxidation performance.

  • Supports solid and stranded copper wires with a secure screw-locking connection

2.2 Industrial-Grade Signal Stability

  • Onboard EMI filter circuits to suppress motor frequency converter and relay switching interference

  • Built-in transient voltage surge protection for sensor and communication lines

  • Reinforced PCB insulation, meeting IEC 61131-2 control equipment standards

  • Low contact resistance, stable transmission for both digital switching signals and 4–20mA analog signals

2.3 Wide Compatibility & System Integration

Fully compatible with Eaton's full automation ecosystem:

  1. XV400 series HMI-PLC touch panels

  2. MP3010 MPrelay motor protection relays
