Product Description:
The IP3202-B520-0000 is a temperature-measuring I/O module from Beckhoff that belongs to the IP Compact Box Units series. Housed in a sealed block suitable for machine-mounted installation, the unit accepts resistance temperature detector (RTD) signals and forwards digitized values to an EtherCAT controller. By locating signal conversion directly on the production line, it reduces wiring runs and helps maintain accuracy in industrial automation systems that monitor process or equipment temperatures.
This compact box provides 4 analog inputs and supports seven common RTD families, listed as PT100/PT200/PT500/PT1000/Ni100/Ni120/Ni1000, so one device can cover multiple sensor standards. Each channel is converted with a resolution of 0.1 °C per digit, allowing fine tracking of thermal changes. A conversion cycle of 260 ms updates the complete data set, which is adequate for slow-to-medium thermal processes. Error LEDs indicate broken-wire conditions, while internal channel-to-control isolation is rated at 500 V to limit fault propagation. Channel-to-channel isolation is omitted to keep the housing compact. Four selectable input filter versions help balance noise suppression against response time, and resistance measurement is available for direct ohmic evaluation when needed.
The enclosure carries a protection rating of IP65/IP66/IP67, so it withstands dust, water jets, and brief immersion without a cabinet. Sensors can be wired using 2-wire or 4-wire techniques through shielded M12 screw-in connectors, keeping installation straightforward. Field power is looped through a single 1 × M8 connector with 4 pins, and the process image occupies 4 × 16 bits inside the PLC memory map, matching the native word size of many controllers. Optional expansion lines expose 4 × 8-bit and 4 × 16-bit blocks for auxiliary status data. The control-to-fieldbus barrier is galvanically isolated to improve system resilience.
