XYCOM 4810ER Industrial Multi-Serial Port Communication Card Detailed Product Description
I. Product Overview
XYCOM 4810ER is an enhanced industrial ISA bus multi-serial port communication expansion card of the XYCOM 4810E series. It is specially designed for the XYCOM 4000 series industrial human-machine terminals and old ISA architecture industrial control hosts. Based on the standard version 4810E, it enhances lightning protection and surge protection, signal enhancement, and wide temperature stability. It focuses on multi-channel isolated serial communication expansion, suitable for the renovation of old equipment in harsh working conditions, multi-device serial port networking, and long-distance data transmission requirements. It is widely used in machine tools, rubber and plastic machinery, assembly lines automation, process control, heavy industry, energy and other industrial scenarios with strong interference.
II. Product Naming and Positioning
The "ER" in the model represents "Enhanced Ruggedized" (Enhanced and Ruggedized), the core of which is to retain all the functions, interface definitions, installation dimensions, and system compatibility of the 4810E, while upgrading the lightning protection circuit, signal driving, and anti-vibration structure. The electrical performance is more stable and the anti-interference ability is stronger. It can be directly exchanged with 4810E and 4810E-LF. It is positioned as a high-reliability and strong anti-interference multi-channel isolated serial port expansion board card, and is the preferred spare part for high-interference industrial sites.
III. Core Functional Characteristics
Multi-channel Independent Serial Port Expansion
Integrates multiple independent serial communication channels, each channel is electrically independent and does not interfere with each other. It can simultaneously connect multiple different types of on-site peripherals, solving the pain point of insufficient native serial ports in the original industrial host, and significantly improving the overall external communication expansion capability.
Three Communication Modes Free Switching
A single channel supports RS-232, RS-422, and RS-485 three industrial mainstream serial port modes. Through the onboard physical dip switch, it can be quickly switched without changing the wiring and program; for short-distance point-to-point use, RS-232 is used, for long-distance bidirectional use, RS-422 full-duplex is used, for bus networking of multiple devices, RS-485 half-duplex is used. It meets the requirements of all scenarios for wiring.
Full Channel Optical Isolation + Lightning Surge Dual Protection
Each channel has an independent optical isolation circuit, and a new TVS lightning protection diode, gas discharge tube, and surge suppression circuit are added. It has high-level withstand voltage isolation and lightning protection capabilities, which can isolate electromagnetic interference generated by motor start-stop, frequency converter, large-power contactor, static electricity shock, ground potential difference, and lightning strike surge, eliminating communication garbled, data disconnection, and interface burnout from the hardware level, and meeting harsh interference harsh working conditions.
Full Frequency Band Communication Rate Compatibility + Signal Enhancement
Supports an industrial full series of common baud rates from 50bps to 115.2Kbps, and the data bits, parity bits, and stop bits can be freely configured. The differential signal driving chip is upgraded, and the signal attenuation in long-distance transmission under RS-485/422 mode is lower, with the farthest transmission distance reaching 1200 meters, significantly improving the stability of long-distance communication.
ISA Bus Driver-Free Adaptation
Uses a standard 16-bit industrial bus interface, directly powered by the host slot, without additional power supply; automatically identifies hardware in old industrial systems such as DOS, WIN95, WIN98, and WIN2000, without complex drivers, only simple configuration of serial port resources can be put into use, deployment is convenient and efficient.
Built-in Terminal Resistor + Bus Impedance Matching
Equipped with a 120Ω communication terminal resistor, a separate dip switch is provided. RS-485 bus networking can directly enable it without additional accessories; a new bus impedance matching circuit is added to effectively eliminate signal reflection in long-distance transmission, ensuring the integrity of long-distance communication signals.
Intuitive Status Light Diagnosis
Configured with power, data transmission, and data reception indicator lights, the operating status of each channel is clear at a glance; maintenance personnel can quickly determine the power-on, data transmission status of the channel, locate the fault point, and reduce maintenance time.
Industrial-grade Reinforcement + Wide Temperature Lead-Free Process
Uses thickened industrial PCB boards, wide-temperature-level components, and lead-free soldering, upgrades the anti-vibration reinforcement structure, strengthens the soldering points of components, and has stronger anti-vibration, anti-powder, and resistance to high and low temperatures; the working temperature covers -20℃ to 70℃, supports 24-hour continuous operation, meeting the requirements of harsh industrial environments. Adopting the industrial standard ISA full-length card structure, the size and installation holes are exactly the same as those of 4810E and 4810E-LF. It is compatible with all the ISA slot industrial control devices of the same specification; the communication output terminal uses strong industrial terminal connectors, with strong shock resistance and less likely to loosen or fall off in vibration environments; the operating power consumption is low, the temperature rise is small, and it does not increase the heat dissipation burden of the main unit; the working temperature is -20℃ to 70℃, the storage temperature is -30℃ to 80℃, the humidity is 5% to 95% without condensation, and the environmental adaptability is excellent.
