Product Description:
The model KL2722-0010 is a Digital Output Bus Terminal used for switching AC voltages. It features a semiconductor triac switch for wear free operation. It handles voltages from 12 V AC to 230 V AC and supports mechanical reversing motors.
The KL2722-0010 bus terminal has two mutually locked outputs with 4 wire connection technology. Each channel can handle a maximum output current of 1 A. It operates at a rotating field frequency between 47 Hz and 63 Hz. The terminal supports both ohmic and inductive loads. Peak currents of 40 A for 16 ms and 3 A for 30 s are supported by the terminal. It comes with a surge protection feature that works when voltage exceeds 275 V. Switch on time ranges from 0.1 ms to 10 ms triggered at zero crossing. The residual voltage of the terminal in the OFF state is a maximum of 1.5 V. Electrical isolation is provided at 500 V (K-bus to field voltage) and 3750 V AC for one minute. The typical leakage current of the terminal is 0.8 mA with a maximum of 1.5 mA per channel. The terminal does not require address or configuration settings.
The current consumption of the Beckhoff KL2722-0010 bus terminal from the K-bus is typically 10 mA. The terminal image contains two output bits. It is especially designed for use with mechanical reversing motors such as blinds. However, it is not suitable for controlling LED loads. The terminal weighs approximately 55 grams. The model is designed for efficient performance with high isolation standards. The integrated features ensure reliable switching in AC control systems. The KL series bus terminal uses triac switching elements for minimal wear and long service life.
Frequently Asked Questions about KL2722-0010:
Q: Can the KL2722-0010 manage high short-term current peaks in AC loads?
A: Yes, the KL2722-0010 supports peak currents of 40 A for 16 ms and 3 A for 30 seconds. This makes it suitable for dynamic load changes in AC circuits.
Q: Does the KL2722-0010 bus terminal provide secure electrical isolation?
A: The KL2722-0010 ensures 500 V isolation between K-bus and field voltage and withstands 3750 V AC for one minute. This meets high safety and separation standards in industrial use.
Q: How does the KL2722-0010 maintain long service life under frequent switching?
A: It uses a semiconductor triac switch for wear free switching operation. The triac element reduces mechanical stress and increases service life in AC control systems.
Q: Is the Beckhoff KL2722-0010 suitable for inductive load applications like motors?
A: Yes the KL2722-0010 supports both inductive and ohmic loads with stable output. Its two locked outputs with 4 wire connection ensure safe motor control.
Q: How much power does the KL2722-0010 draw from the K-bus during operation?
A: The KL2722-0010 consumes only 10 mA from the K-bus under typical load. It draws additional current only through leakage and active power contacts.
