RS232 DB9 to RS485/RS422 Converter with 6-Pin Terminal Block Adapter – Industrial Serial Protocol Bridge

Simplify serial communication conversions with this RS232 DB9 male to RS485/RS422 terminal block adapter, designed for industrial IoT, automation, and hobbyist projects. Convert RS232 signals to differential RS485/RS422 protocols using its 6-pin screw terminal block, supporting 300V voltage and 1Mbps data transfer. Features a panel-mountable design with gold-plated contacts and TUV-certified terminals for reliable, vibration-resistant connections.

Technical Specifications

Category Details
Interface DB9 female (RS232) to 6-pin terminal block (RS485/RS422)
Protocol RS232 to RS485/RS422 bidirectional conversion
Voltage/Current 300V AC/DC, 5A max (continuous)
Wire Compatibility 22–28AWG solid/stranded wires (POTS, Ethernet)
Termination Screw-down clamps (M3 screws) with 3.81mm pitch (TUV-certified)
Shielding Aluminum foil + braided copper (85% coverage)
Material UL94 V-0 flame-retardant PVC (black housing)
Dimensions 32mm (L) × 22.5mm (W) × 11mm (H)
Mounting Panel-mountable (up to 1.6mm thickness)

Core Advantages

  1. Plug-and-Play Conversion
    • Directly converts RS232 (DB9) to RS485/RS422 for multi-drop networks.
    • No software configuration required—hardwired for automatic protocol switching.
  2. Industrial-Grade Performance
    • 3.81mm Pitch Terminals: TUV-certified for secure wire termination.
    • Gold-Plated Contacts: 50μ” thickness for 10,000+ mating cycles.
  3. Safety & Reliability
    • Reverse Polarity Protection: Prevents damage from incorrect wiring.
    • EMI Immunity: Shielded design for noise-free data transmission.
  4. Flexible Installation
    • Panel-Mountable: Fits into standard 1.6mm-thick enclosures.
    • Isolating Pad: Reduces electrical noise and prevents slipping.

Design Features

1. Terminal Block Layout

  • Pins:
    • 1: RS485+ (A)
    • 2: RS485- (B)
    • 3: GND
    • 4: RS422 TX+
    • 5: RS422 TX-
    • 6: RS422 RX+
    • 7: RS422 RX- (optional)

2. DB9 Pin Assignment

  • DB9 Male (RS232):
    • 2: TXD
    • 3: RXD
    • 5: GND

3. Safety Mechanisms

  • Overcurrent Protection: Automatic shutdown at 6A (5A continuous).
  • Surge Protection: 1.5kV ESD rating for transient voltage spikes.

Applications

  1. Industrial Automation
    • PLCs, sensors, and motor drives in factory floors.
    • Long-distance communication between devices (RS485 supports 1.2km).
  2. Smart Infrastructure
    • IoT gateways, smart meters, and building automation systems.
    • Security cameras and access control panels.
  3. Hobby & DIY Projects
    • Converting legacy RS232 devices to modern RS485 networks.
    • Raspberry Pi/Arduino setups requiring serial communication.

Installation Guide

Step 1: Prepare Wires

  • Strip 6–8mm of insulation from wire ends.

Step 2: Connect to Terminal Block

  1. Loosen the screws on the terminal block.
  2. Insert wires into labeled slots (e.g., Pin 1 = RS485+).
  3. Tighten the screws to secure the connection (0.5–0.8Nm torque).

Step 3: Attach to RS232 Device

  • Plug the DB9 male end into a PC, PLC, or RS232-enabled device.

Step 4: Test

  • Use a loopback test or serial monitor software to verify communication.

Troubleshooting Tips

Issue Solution
No Data Transfer Check wire polarity (RS485+/- must match network).
Data Errors Ensure termination resistors (120Ω) are installed on the RS485 bus.
Overheating Reduce load to ≤5A; ensure proper ventilation.
