The B&R 4B1270.00-390 is a P127 COMPACT HMI CAN operator panel designed for industrial machine control and monitoring. Its compact 153 × 120 × 43.7 mm housing combines a four-line, 20-character-per-line LCD with a 20-key membrane keypad. Yellow/green LED backlighting and adjustable display contrast provide clear text presentation, while 14 keys feature yellow LED illumination and can be individually labeled using legend strips.
An electrically isolated CAN interface with a 9-pin D-type connector enables communication with compatible automation equipment. Rear-accessible hexadecimal switches allow the CAN node number and baud rate to be configured. The panel operates from a nominal 24 VDC supply, accepting an input range of 18–30 VDC through a three-pin terminal block. This compact interface is suited to applications requiring text-based status displays and physical keypad operation.

What type of operator panel is this?
The 4B1270.00-390 is a P127 COMPACT HMI CAN operator panel. It combines a character display, membrane keypad and electrically isolated CAN interface in a compact housing for operator interaction with industrial equipment.
What information can the display show?
The LCD displays four lines of 20 characters each. This character-based format is suited to text such as equipment status, operating values and operator prompts. The display has yellow-green LED backlighting, and its contrast can be adjusted using the keys.
How many keys does the panel have?
The panel has 20 membrane keys, including 14 with yellow LED illumination. This keypad configuration is specific to the 4B1270.00-390 variant.
Can the key labels be customized?
Yes. The 14 lower keys can be labeled using legend strips, allowing their labels to match the functions assigned to them on the machine.
What power supply does the panel require?
The panel requires a nominal 24 VDC supply and accepts an input range of 18 to 30 VDC. Power is connected through a three-pin terminal block.
What is the panel's power consumption?
The documented typical power consumption is 2.7 W, with a maximum of 3.0 W. For hardware revisions earlier than F0, the listed values are 2.2 W typical and 2.5 W maximum. Check the unit's hardware revision when assessing its power requirements.
Which communication interface does the panel use?
The panel uses an electrically isolated CAN interface with a nine-pin male D-type connector. The connector provides CAN_L on pin 2, CAN_GND on pin 3 and CAN_H on pin 7. The remaining pins are marked as not connected.
How are the CAN baud rate and node number configured?
The CAN baud rate and node number are configured using two hexadecimal switches, SW1 and SW0, accessible through openings at the rear of the housing. SW1 determines the baud rate and part of the node address, while SW0 determines the remaining part of the node address.
What happens if an invalid CAN switch setting is selected?
An invalid switch combination is indicated on the display by 'CAN Node number: --' and 'Baud rate: --'. Only the documented switch combinations should be used.
What are the panel's housing dimensions?
The documented housing dimensions are 153 × 120 × 43.7 mm. These are overall housing dimensions rather than panel cutout dimensions, so the mounting layout should be checked separately before installation.
What operating temperature range should be considered for installation?
The specified operating temperature range is 5°C to 50°C. For installations in the Philippines, assess the temperature at the panel's actual mounting location, particularly where enclosure heat could raise it above the surrounding room temperature.
