Product Description:
Beckhoff IE2021 is an 8-point digital output extension box that is included in Beckhoff's modular automation hardware line. The box is built for easy integration into industrial automation setups, offering a fault-tolerant connection between a central automation controller and field actuators.
The IE2021 box has eight digital output channels with M8 screw-type terminals for safe cabling. One channel can be driven with an output current as high as 2 A, and each individual channel is short-circuit protected. The box has a nominal output voltage of 24 V DC with ±15% - +20% tolerance. Ohmic, inductive, and lamp loads are all supported, with reverse polarity protection. Electrical isolation of the fieldbus from the control voltage is through the IP-Link interface. The current consumption of the module from the supply voltage is 25 mA, not including sensor current, and auxiliary power consumption is around 30 mA per channel. Plastic is used in the housing, and it can be mounted on a DIN rail. Temperatures range from 0°C to 55°C for use and from -25°C to +85°C for keeping. Each channel has four LEDs that show the signal state, and the power source is connected by a single M8 male socket that is coded A.
The IE2021 digital output extension box has 8 outputs with a bit width in the image of the process and can be installed in a variety of automation designs. The box has an ingress protection grade of IP65, IP66, or IP67, and it meets EN 60068-2-6 and EN 60068-2-27 for it to be resistant to vibration and shock. The high electrical separation of the device makes sure that the system is safe and reliable. Integration in the fieldbus works well when IP-Link is compatible.
Frequently Asked Questions about IE2021:
Q: Does the IE2021 support short-circuit protection per channel?
A: Yes, the extension box features individual short-circuit protection for each channel. This protects both the device and connected loads during faults.
Q: Do the outputs of IE2021 support different load types?
A: The extension box supports ohmic, inductive, and lamp loads. This allows flexible use with various actuator types in automation systems.
Q: How does the IE2021 indicate output signal states?
A: The extension box uses LEDs to indicate the signal state of each output channel. This provides clear and immediate visual feedback for diagnostics.
Q: Why does the IE2021 use M8 screw-type connectors?
A: M8 screw-type connectors on the extension box ensure secure and vibration-resistant wiring. This enhances connection reliability in dynamic environments.
Q: Does the IE2021 provide electrical isolation via IP-Link?
A: Yes, the extension box provides electrical isolation between control voltage and fieldbus using IP-Link. This improves system safety and reduces interference.
