Product Description:
Beckhoff makes the EL1804 digital input terminal that is designed to work well with industrial automation systems because it turns control signals into data. The terminal is perfectly made, so it can easily handle binary signals. This makes it perfect for use in control systems that need to get accurate signals.
A 24 V DC base voltage can be used with the EL1804 digital input terminal as long as it stays between -15% and +20%. Each of the four input channels can handle a signal value between -3 and +5 V for a "0" state and between 11 and 30 V for a "1" state. The usual input current is 3 mA, and the reaction time is 3 ms. The digital input terminal can be used for tasks that require quick reaction. The terminal's enclosure is constructed from high-density plastic, which enhances its durability without affecting its size. The system is safe because it sends signals safely by separating the E-bus from the field potential by 500 V.
The compact EL1804 digital input terminal can be mounted safely on a 35 mm DIN rail in line with EN 60715 standards. The terminal is 12 mm wide and 100 mm tall. Solid and fine-stranded wire connections can be accommodated by the 16 connecting points on a 12 mm-diameter terminal block. The double slot and key connection allow for the secure placement of multiple units in close proximity. As a result of its sensor input voltage, this flexible terminal can be used in a lot of different situations. It meets the standards of EN 61131-2 type 1/3 input and is a great and reliable choice for use in automatic systems.
Frequently Asked Questions about EL1804:
Q: Does the EL1804 support tool-free wiring?
A: Yes, the input terminal allows tool-free wiring for solid conductors that use a direct plug-in technique, which simplifies installation and maintenance.
Q: Why does the EL1804 have 500 V electrical isolation?
A: The input terminal provides 500 V isolation between the E-bus and field potential that protects the automation system from electrical noise and potential surges.
Q: How does the EL1804 indicate channel status?
A: The input terminal features signal LEDs for each channel that display the current input state, allowing for quick and easy status monitoring.
Q: Do the EL1804 input channels require configuration?
A: No, the input terminal does not require address or configuration settings that streamline integration and reduce setup time.
Q: Why does the EL1804 use polycarbonate housing?
A: The input terminal uses a polycarbonate housing that provides durability and electrical insulation for the internal circuitry, ensuring long-term reliability.
