Product Description:
Beckhoff's EL3004 Analog input terminal is designed for industrial automation applications that require precise voltage signals. The terminal combines dependable analog input processing and Ethernet CAT transport. The terminal features four single-ended input channels capable of measuring data up to ±10 V.
The EL3004 analog input terminal has a 12-bit precision, including the sign, which equals 16 bits. This guarantees accurate analog-to-digital conversion. The conversion time is typically 0.625 ms, but can be adjusted. The input filter's 1 kHz cut-off frequency lowers noise. The E-bus is electrically shielded from signal power by 500 V and has an internal resistance of over 130 kΩ. Over 0.3% of measurements from 0°C to +55°C are within 0.5%, with more than 0.5% in the higher temperature range. The input terminal requires 130 mA of E-bus power. Enable and disable FIR/IIR filters, monitor limit values, and view process data overloads. The terminal works from -25°C to +60°C, and it maintains a temperature range of -40°C to +85°C. The input terminal is also capable of maintaining a relative humidity of 95% without experiencing dampening. The security-certified terminal satisfies CE, UL, ATEX, and IECEx standards.
The EL3004 input terminal accommodates wires and ferrules that are solid or detached and measure 0.08 mm³ to 2.5 mm³ and 0.14 mm³ to 1.5 mm³, respectively. The terminal is possible to strip down to a depth of 8-9 mm, and it approximately weighs 70 grams. The terminal is capable of operating at a maximum voltage of 30 volts. The terminal is guaranteed to operate effectively in automation systems that necessitate the reception and processing of analog signals. The terminal undergoes testing to guarantee that it meets international standards and functions correctly.
Frequently Asked Questions about EL3004:
Q: Why does EL3004 offer 500 V electrical isolation?
A: The 500 V electrical isolation between the E-bus and signal voltage protects the control system from electrical faults. This enhances operational safety.
Q: How does EL3004 ensure measurement accuracy?
A: The input terminal maintains a measurement error below ±0.3% of full scale at standard temperatures. This accuracy is crucial for precise analog signal processing.
Q: Do EL3004 terminals support DIN rail mounting?
A: Yes, the input terminal is designed for DIN rail mounting according to EN 60715. This simplifies integration into control cabinets.
Q: Why is the input filter cut-off frequency set at 1 kHz?
A: The 1 kHz input filter cut-off frequency helps suppress high-frequency noise. This ensures cleaner signal acquisition for automation processes.
Q: How does EL3004 handle wiring and connections?
A: The input terminal supports solid and stranded wires from 0.08 to 2.5 mm² and ferrules from 0.14 to 1.5 mm². This allows versatile wiring options.
