Product Description:
The KL2784 Bus Terminal is developed by Beckhoff. It connects input and output signals from sensors, actuators or machines to a fieldbus system or PLC and it is relatively energy efficient.
The KL2784 bus terminal has a strong protection between internal logic and field-side wiring which reduces the risk of signal interference or component damage. It can tolerate short surges during switching events up to 50 amperes for 10 ms. It communicates 4 output bits to the controller which represents 4 discrete output channels. It provides solid state switching that mimics relay behavior but offers faster, quieter and more durable operation. There are 4 independent output channels and each is capable of closing a circuit. To store the module in a place the temperature of the environment must be between -25 and 85 centigrade. Each output can drive a load drawing up to 2 amps which is suitable for light actuators or indicator loads. It has relatively slower turn off time typically 30 ms or maximum 50 ms which may be due to load type or protection features. It can withstand a maximum voltage of 80 volts before insulation fails.
The KL Analog series module has a very lower resistance of 0.03 ohms in closed state which allows efficient current flow with minimal voltage drop. It comes with typically 1.8 and max 5 ms of switching on speed which is suitable for applications requiring timely control. It supports both AC and DC output loads within 0…30 V AC/DC range which makes it ideal for flexible industrial automation applications in mixed voltage environments. It lacks built in protection against shorts due to which external fusing or design precautions are necessary.
Frequently Asked Questions about KL2784:
Q: Why does the KL2784 support both AC and DC loads up to 30 V?
A: This allows flexible deployment across various devices and voltage types. It improves compatibility in mixed-signal industrial control systems.
Q: How does low on-resistance in KL2784 improve system efficiency?
A: With only 0.03 Ω resistance, power losses are minimized during switching. This reduces heat generation and enhances overall performance.
Q: Why is fast switching-on speed important in the KL2784 Bus Terminal?
A: A 1.8 ms typical turn-on speed ensures quick response in control tasks. It's essential for time-sensitive operations like motor starts or actuators.
Q: What is the advantage of solid-state switching in KL2784 over mechanical relays?
A: Solid-state switches offer silent, wear-free operation with faster cycle rates. This increases service life and reduces maintenance frequency.
Q: How does peak current handling of KL2784 help in inductive load applications?
A: It supports brief inrush currents up to 50 A, protecting against false shutdowns. Ideal for solenoids or motor startups.
