TTL 485 PRO Serial Module with 2 LED Indicator Aluminum Alloy SP3485 Isolated Interconverter Serial

About this item

• Feature: 1. High Speed Communicating with SP3485: Utilizing the original SP3485, this module ensures stable high speed communicating with excellent compatibility. It seamlessly converts TTL signals to 485 signals without requiring receive to transmit control, making it as easy to operate as a standard serial port. 2. User Friendly Pluggable Terminal Blocks: The serial module features 5.08mm pluggable terminal blocks for smoother, robust connections. Its design ensures that connections are secure and dependable while also allowing for easy setup and maintenance. 3. Simple 5V Power Supply Compatibility: The circuit uses only 5V power supply, the output signal level of the TTL signal terminal is 5V (same as the power supply voltage), and the input signal level is 5V (compatible with 3.3V signal input). 4. Enhanced Guard: TTL end with overcurrent guard, surge guard. It can ensure the stable output of current and voltage, and strong shock proof. 485 terminal with overcurrent guard, surge guard, thunderstrike gas discharge guard circuit. 5. Improved Signal Stability with Optional Termination Resistor: The module includes a 120R termination resistor pad, which can be used to enhance signal transfer stability and reduce interference, ensuring more dependable communicating in diverse environments. Specification: Item Type: TTL 485 PRO Serial Module Material: Aluminum Alloy Baud Rate Support Range: Up to 2Mbps (In actual application, the baud rate supported by this module is limited by the baud rate supported by the access equipment at both ends, and needs to be adjusted according to the actual situation.) LED Indicator: Onboard two LED indicator lights for indicating the sending and receiving status of the circuit. TTL Indicator Light: Green light on when receiving data on the TTL side 485 Indicator Light: Green light on when receiving data on the 485 side.
