NX-AD3203 | Omron | Contrôleur d'automatisation machine

Description

Designed for reliable analog-to-digital conversion within the Sysmac automation platform, the NX-AD3203 current input module offers precise signal processing for modern industrial environments. This 4-point analog input unit connects directly to the NX-series I/O system, allowing seamless integration with EtherCAT or EtherNet/IP couplers. Featuring single-ended inputs tailored for standard 4 to 20 mA process loops, the module is engineered for applications demanding rapid measurement capabilities and stable data transmission.

The unit functions using a free-run refreshing cycle and delivers a fast conversion speed of 250 microseconds per point. It translates analog process signals into digital values with a resolution of 1/8000, ensuring highly accurate monitoring of field instruments. Equipped with a 12-terminal screwless clamping block, the unit facilitates rapid wiring and exceptional vibration resistance in demanding machinery setups.

Features

• Four independent, single-ended analog current input channels.
• Standard 4 to 20 mA input range compatible with most process transmitters.
• Fast conversion speed of 250 microseconds per point for high-speed loop control.
• 1/8000 resolution delivers fine-grained measurement data.
• Free-run refreshing mechanism for consistent synchronous backplane updates.
• Screwless clamping terminal block with 12 points simplifies installation and reduces maintenance overhead.
• Compact 12 mm width design optimizes space utilization on the DIN rail.

Applications

• Process manufacturing systems involving flow, level, temperature, and pressure monitoring.
• Machine control units demanding high-speed sensor integration.
• Water and wastewater processing instrumentation setups.
• Factory automation and packaging machinery integrated via EtherCAT networks.

Installation Guidelines

• Ensure the system power is completely shut off before mounting or removing the module from the NX-bus unit alignment.
• Mount the unit securely onto a standard 35 mm DIN rail, verifying that the DIN rail locking hooks are fully engaged.
• Strip field cables to the manufacturer-specified length before inserting them into the screwless clamping terminals to prevent short circuits.
• Use shielded, twisted-pair cables for all analog 4 to 20 mA current loops to minimize electromagnetic interference.
• Ground the cable shields at a single point in the control panel to protect the low-voltage analog signals from ground loop noise.
