Product Description:
The EL1094 is a Digital input terminal designed for EtherCAT-based control systems by Beckhoff. The company is known to manufacture components that are compatible with automation design and fieldbus technology. The terminal enables the use of four-channel ground-switching inputs. It works with logic that runs on 24 V DC and can connect straight to sensors.
The EL1094 digital input terminal operates on a 24 V DC power supply having tolerance from -15% to +20%. It has four digital sources that can be connected using two wires. Each channel has reasoning for switching the ground that works with most sensor setups. The incoming current is usually 3.0 mA per channel, which makes the device use less energy. The input filter lasts for 10 µs, which lets signals respond quickly. Different voltage values show different logic states. The input terminal has 500 V of electrical separation on the inside that keeps the E-bus and field potential separate. Power from the power ports usually takes 20 mA, and power from the E-bus takes about 90 mA. It does not need to be addressed or configured by hand, which makes system interaction easier. On the terminal, there are LED lights that show the state of each input channel. The case for the terminal is very small, measuring 12 mm across, and it fits on a 35 mm DIN rail.
The temperature range of 0°C to +55°C is the most common for cabinet settings, and this is where the EL1094 digital input terminal operates. The also meets the EMC standards EN 61000-6-2 and EN 61000-6-4, which make sure that it works with electric fields. The terminal can be used in signal acquisition lines and control interfaces that need to be small and precise.
Frequently Asked Questions about EL1094:
Q: Does EL1094 require configuration or addressing setup?
A: The input terminal does not require manual configuration. This reduces installation steps and minimizes errors during system integration.
Q: Why does EL1094 use a 2-wire input connection?
A: The 2-wire setup in the input terminal simplifies wiring. It enables direct sensor connection without requiring external wiring adjustments.
Q: How does EL1094 manage power consumption efficiently?
A: The input terminal draws only 20 mA from power contacts and 90 mA from E-bus. This keeps the power usage controlled.
Q: Do EL1094 voltage levels define logic clearly?
A: Yes. the input terminal uses 0–7 V DC for logic high and 18–30 V DC for logic low to avoid signal noise.
Q: Why does EL1094 offer a 500 V isolation barrier?
A: The 500 V isolation separates field and E-bus voltages. It protects the control system from transient electrical surges.
