Product Description:
The Beckhoff ELM3348-0003 EtherCAT Terminal is a robust module designed to meet the needs of industrial workplaces.
The terminal is a perfect tool for industrial automation temperature monitoring systems since it has 8 input channels that enable accurate differential signal measurement. The gadget has small thermocouple connectors that work with a variety of thermocouple kinds and connects via two wires. Since the ELM3348-0003 Terminal can multiplex for high-speed data gathering, its sampling speed can approach 1 ms/1 ksps per channel. By choosing the oversampling factor, users may increase measurement accuracy by adjusting sampling rates from n = 1 to 20. Because the terminal's internal resistance is more than 4 MΩ, it maintains strong signal integrity. With its 24-bit resolution, which users may adjust to obtain readings accurate to within 0.1°C, this terminal offers the highest level of precision for measuring temperatures. Despite having an internal cold spot, type K thermocouples have an accuracy of < ±0.5°C at 23°C and < ±0.9°C in the 0–55°C range. To protect connected devices from voltage spikes, the terminal provides isolation between the bus and channels, which can tolerate up to 707 V DC (depending on type testing).
The industrial-grade terminal is perfect for various temperature-managed applications since it operates between 0°C and 55°C but requires storage temperatures between -25°C and +85°C. The installed module produces normal thermal dissipation of 2 W to optimize power efficiency. Advanced functionality of this terminal comprises an AGND (Analog Ground) lead-out, together with common mode measurement and free numeric filter and TrueRMS functionality and integrator/differentiator options and non-linear scaling, and PeakHold. It can be purchased at Wake Industrial with a one-year warranty.
