Product Description:
The 4B1270.00-K04 Compact CAN HMI is a powerful operator interface terminal. It is one of B&R Automation's compact HMI products, designed for industrial control. It contains a membrane keypad with 24 tactile keys and 12 programmable LEDs. The numeric keypad has keys 0-9, Enter, and navigation keys.
The display of 4B1270.00-K04 Compact CAN HMI is a 4-line monochrome LCD with green backlight to ensure good readability. It talks through the CANopen protocol with a 9-pin D-sub CAN connector. The data transmission rate supported is from 125 to 500 kbit/s. Node addressing can be anything from 1 to 32, set through DIP switches. It runs on the power supply of 24V DC with a tolerance of ±25%. Power input through a 3-pin terminal block connector. The maximum power consumption of the unit is generally less than 6 Watts. The 4B1270.00-K04 Compact CAN HMI functions properly between 0°C and +50°C. It can withstand storage temperatures from -20°C to +60°C without loss of performance. It can handle up to 85% relative humidity, non-condensing, during operation. The installation altitude is up to 2000 meters above sea level. The unit can withstand vibrations of up to 2g as per EN 60068-2-6. It can withstand mechanical shocks up to 15g as per EN 60068-2-27 standards.
The front panel of 4B1270.00-K04 Compact CAN HMI is IP65 rated. It is appropriate for dusty and wet applications. The IP20-rated rear portion of the housing needs enclosures to be installed. The HMI has UL, CE, and cUL ratings for international industrial applications. The stainless steel chassis makes it industrial hardened. The encoder interface doesn't apply because this HMI is button-based. The HMI is perfect for machine control, diagnostics, and basic user interactions.
Frequently Asked Questions about 4B1270.00-K04:
Q: Why is the green backlight used in 4B1270.00-K04 Compact CAN HMIs LCD display?
A: The green backlight improves visibility in low-light or industrial lighting conditions, ensuring operators can read data clearly. This helps maintain operational efficiency.
Q: How does the stainless steel chassis of 4B1270.00-K04 improve durability?
A: The stainless steel chassis ensures industrial-grade toughness and corrosion resistance, extending operational life in harsh environments. It also provides additional mechanical protection.
Q: What advantage does the 2g vibration resistance provide in 4B1270.00-K04 Compact CAN HMI?
A: 2g vibration resistance ensures stable operation in high-vibration environments like machinery installations. This prevents malfunction during mechanical stress.
Q: Why is 15g shock resistance essential for 4B1270.00-K04 Compact CAN HMI in industrial environments?
A: 15g shock resistance allows the unit to withstand accidental impacts and mechanical shocks. This enhances reliability in rough industrial conditions.
Q: How does the non-condensing 85% relative humidity tolerance benefit the 4B1270.00-K04 Compact CAN HMI?
A: Withstanding up to 85% relative humidity without condensation ensures consistent performance in humid environments. This prevents moisture-related failures.
