1. Easy to install. Equipment panel. Only a square hole is needed on the panel to embed, no need to install screws.
2. Built-in switching power supply circuit, wide input voltage range, high conversion efficiency, can work continuously for a long time.
3. Power input with reverse connection protection and over-current protection.
4. Industrial grade RS485 chip, bus interface with lightning and surge protection, anti-static, over-voltage, over-current protection.
5. The chips are all original and brand-new genuine products with industrial grade temperature range.
The host computer (computer, industrial control machine, microcontroller, PLC, HMI touch screen, etc.) can send commands through RS485 bus, RS232 or TTL interface to control the display content of the display. It supports common ASCII protocol and Modbus RTU protocol. The product is mainly used in production lines, industrial control equipment, automotive instrumentation, storage electronic tags and other fields.
1. Various communication methods are available: RS485, RS232, TTL (specify one of them when ordering), support MODBUS RTU protocol and simple ASCII protocol, protocol automatic identification.
2. Can display integers, negative signs, decimal points, ABCDEFPL and other ASCII characters, is the market. On the support of ASCII characters comprehensive - a digital tube display.
3. Support electronic label function,. The initial display content can be set. Widely used for storage bit number label. For example, display
"A001", "B002", "C003", etc.
4. Support the brightness adjustment of strokes, with 7 grades of brightness.
5. Support modifying baud rate ( 1200bps-1 15200bps), covering several commonly used baud rates.
6. Support modifying stop bit and parity bit.
7. Can choose the initial display content of power on, display 0, display 485 address, display any content specified by the user, etc.
8. A 485 bus can be connected to 32 digital tubes (without relay), plus relay can be connected to 254.
9. Provide supporting PC software, easy to test and modify parameters.
10 product model number suffix with T version supports the display of the clock colon, this model number and function is added after V2.3 version.
11. V2.4 increase the flashing display function, can set a certain - - bit, a certain number of bits, all flashing.
12. V3.0 version of some 3-bit or 4-bit 232, 485, TTL communication interface of the digital tube screen increased with a sub-meter head function.
The main meter head responsible for communication with the host computer can carry up to 31 subheads, which can save more than 50% of the cost for users in some applications without any changes to the user program.
13. The new model with SB suffix is a single bus interface sub-meter head, this kind of digital tube screen only needs to use one 3-core wire to connect with the main meter head.
This kind of digital tube screen only needs one 3-core wire to connect with the main meter head, which can be connected with more than one hand, cheap and convenient wiring. But can not be used independently, need to be hooked up behind the main meter head with the same number of bits to use.
