Description

Designed for high-precision temperature sensing in distributed control architectures, the Beckhoff EJ3202 is a dual-channel EtherCAT plug-in module designed for direct mounting on application-specific signal distribution boards. This space-saving module enables direct connection of Resistance Temperature Detectors (RTD) using 2-wire or 3-wire cabling methods. By supporting a broad range of RTD sensors like Pt100, Pt1000, and Ni100, the module delivers highly accurate temperature measurement capabilities directly into the EtherCAT communication network, making it highly suitable for demanding industrial machinery and automation environments.

Features

Two independent channels for RTD input.
Supports 2-wire and 3-wire connection configurations (2-wire as default).
Compatible with a wide array of temperature sensors: Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni1000, and KTY sensors.
Integrated digital filter and configurable limit value monitoring for enhanced process control.
Direct installation onto EJ-series signal distribution boards, minimizing wiring complexity and footprint.
Provides 500 V electrical isolation between the E-bus and field potential.

Applications

Machinery and equipment manufacturing with customized signal boards.
Industrial furnace and HVAC control systems.
Process manufacturing requiring precise thermal profiling.
Food and beverage production lines requiring clean, distributed I/O installations.

Installation Guidelines

Mounting: Ensure the module is properly plugged into the matching application-specific signal distribution board. Confirm latching mechanism is secure before powering the system.
Wiring: For 3-wire connections, ensure all lead wires have equal resistance to minimize measuring errors. Keep sensor cables separate from high-voltage motor cables to prevent electromagnetic noise coupling.
Thermal Management: Maintain standard operating ambient temperature range of -25 to +60 degC. Ensure adequate clearance for convection cooling inside the enclosure.
Grounding: Connect shielding of the RTD cables directly to the ground bus at the entry point of the control panel to minimize external interference.
