Product Description:
The KM2774-0000 terminal module from Beckhoff precisely controls up to four AC motors to make it perfect for automation jobs like blind or jalousie motors. Beckhoff focuses on industrial automation and control systems and is known for being reliable. For accurate motor control tasks, the KM2774-0000 is perfect because the terminal has high-performance features that meet strict safety and control standards.
The KM2774-0000 terminal module has four triac outputs that can handle 80–230 V AC and a maximum of 1.5 A per channel. There are three interlocked triac outputs and three digital inputs on each motor channel. This makes push-button operation at 24 V DC easy and effective. Each channel has ground-switching digital outputs that connect 24 V DC devices that draw up to 20 mA. When the voltage goes above 275 V AC, overvoltage protection kicks in to protect the linked equipment. Surge current protection can handle up to 40 A for 16 ms, and the overcurrent limit can be changed for each channel. From 0.1 to 10 ms, the KM2774-0000 can turn on with zero-crossing switching. The KM2774-0000 is built to last and can be mounted on DIN rails that are compatible with EN 60715 standard rails.
Temperatures from 0°C to +55°C and humidity levels up to 95% are all within the module's operating range. With its 135 mm x 100 mm x 40 mm size and 270 grams weight, the KM2774-0000 is a small but effective control panel option. The module's electrical isolation is listed at 3750 V AC isolation for one minute and 500 V between the K-bus and field voltage. Beckhoff's KS2000 software allows users to change settings like current limits and to process data transfers. All our products come with a one-year replacement guarantee and can be shipped anywhere worldwide.
Frequently Asked Questions about KM2774-0000:
Q: Why does KM2774-0000 have 24 V DC inputs?
A: The 24 V DC inputs are for easy push-button connections. They allow precise control for each motor channel in automation tasks.
Q: What is the purpose of KM2774-0000’s surge protection?
A: The surge protection handles up to 40 A for brief periods. This feature prevents damage to connected motors during power surges.
Q: How does KM2774-0000 benefit from overcurrent limits?
A: Adjustable overcurrent limits protect motors from excessive current. They ensure that each channel operates within safe current thresholds.
Q: Why does KM2774-0000 include status LEDs?
A: Status LEDs provide real-time system monitoring. They indicate supply voltage presence, data transmission, and overtemperature, enhancing user control.
Q: Why is KM2774-0000 designed for DIN rail mounting?
A: DIN rail compatibility ensures quick installation and stability. It aligns the module with standard industrial mounting requirements for automation panels.
