Product Description:
The EL3692 analog input terminal from Beckhoff is designed to directly measure resistance and can accommodate two input channels. Beckhoff is known for making automation solutions that work well with other automation systems. The terminal works well for measuring things and can be used in situations where accurate resistance tracking is needed.
On the EL3692 analog input terminal, there are nine distinct measuring ranges, which span from 0 to 100 MΩ to 0 to 10 MΩ. This facilitates the adaptation to a variety of sensor types and applications. The device can use both 2-wire and 4-wire measurement methods. The 4-wire method is more accurate because it accounts for lead resistance. In 4-wire mode, the terminal has a resolution of 24 bits and a measurement error of less than ±0.5% compared to the full-scale number. The E-bus supplies power to the input interface, which typically requires 220 mA. It comes with an input filter that has a limit frequency of 100 Hz and built-in LEDs that show when the wire fails. Depending on the measure range and settings, the conversion time can be between 10 to 400 ms. The terminal is inside a small plastic case that is 12 mm x 100 mm x 68 mm and is made to be mounted on a DIN rail. It meets the standards for EMC and shaking and is approved by CE, CCC, UL, ATEX, and IECEx.
The EL3692 analog input terminal is a reliable device because it automatically chooses the range and gives error feedback for wiring problems. Within a temperature range of 0°C to 55°C, the input end can handle up to 95% relative humidity without condensation. When measuring resistance and keeping the signal strong at the same time, this terminal can be used.
Frequently Asked Questions about EL3692:
Q: Does EL3692 support both 2-wire and 4-wire measurement?
A: Yes, the input terminal supports both 2-wire and 4-wire measurement methods. The 4-wire method compensates for lead resistance and improves accuracy.
Q: Why is the input filter limit frequency 100 Hz in EL3692?
A: The 100 Hz input filter limit frequency in input terminal helps reduce noise and interference. This ensures stable and accurate resistance measurements.
Q: How does EL3692 indicate wiring failures?
A: The input terminal uses integrated LEDs to indicate wiring failures or broken wires. This feature enables quick diagnostics and system maintenance.
Q: Why is electrical isolation important in EL3692?
A: Electrical isolation of 1500 V between the E-bus and field potential in the input terminal protects the system and ensures signal integrity during operation.
Q: Does EL3692 allow for automatic range switching?
A: Yes, the input terminal supports automatic range switching or manual control via the system controller. This enhances measurement flexibility and efficiency.
