Industrial 232 485 PRO Converter Isolated Signal TTL to Serial Port Module Adapter

Feature: 1. STABLE CONNECTION: Using the original SP3485, possess stable performance, up to industrial design standards. The module realizes the mutual transfer of TTL signal and 485 signal. Onboard automatic transceiver conversion circuit, no need to receive send control, so that the interface communicating at both ends is more rapid and stable 2. POWER SUPPLY VOLTAGE: Using 5.08mm standard connector, bring fluent insertion and removal, solid and trusted. The circuit only uses 5V power supply, the TTL signal end output signal is 5V(the same as the power supply voltage), the input signal is 5V(compatible with 3.3V signal input). When the module is working, the power supply voltage must be connected to the TTL end 3. ISOLATED SIGNAL: Serial converter uses large package components, more stable and trusted. With separate power isolation and signal isolation circuits. The onboard digital isolator has excellent performance characteristics and reliability to isolate the signal and make the transmitted signal more stable. Onboard DC DC power supply isolation provides stable isolation voltage and output short circuit protecting, and no additional power supply is required at the isolation end 4. STRONG PROTECTING: TTL terminal has overcurrent protecting and surge protecting functions, which can ensure stable output of current and voltage and strong shock proof. 485 end with overcurrent protecting, surge protecting, thunder gas discharge protecting circuit. On board TVS(Transient Voltage Suppressor tube) can effectively suppress the surge voltage and transient peak voltage in the circuit to protect the rear circuit and equipment 5. STABLE TRANSMISSION: Serial port converter onboard self restoring fuse to ensure stable current and voltage output, prevent overvoltage and electrostatic discharge, strong impact prevention. The onboard GDT gas discharge tube can be used to discharge powerful thunder current into the earth, so that the subsequent circuit and equipment can avoid being damaged by surge impact. The 120R terminal resistor pad is reserved on the board, which can increase the stability of signal transmission and reduce interference Specification: Item Type: Industrial 232 485 PRO Converter Material: Aluminum alloy Baud Rate Support Range: 422: less than 2M Bps(self Transmitting Test, Actual Use Should Reference The Baud rate range of both devices) 485: less than 2M bps(not standard value, actual use should reference the baud rate range of both devices) Onboard two LED indicators for indicating the working status of the circuit. TTL Side Indicator Light: Indicates the receiving signal on the TTL side, blinking when the signal flows from TTL to 485422 422485 Side Indicator Light: Indicates the transmitting signal on the TTL side, blinking when the signal flows from 485422 to TTL.
