Waveshare Rail-mount TTL To RS485 Galvanic isolated Converter, 600W Lightning proof & Anti-Surge, Multi-Isolation Protection.TTL TO RS485 (B) is an industrial-grade rail-mounted electrically isolated TTL-to-RS485 serial converter.
Specifications:
- Power supply: 3.3V ~ 5V
- Protection: over-voltage, reverse-proof
- Device Port: TTL/RS485 standard compatible
- Connector: screw terminal
- Transmission distance: about 10m
- Transmission mode: point-to-point
- Protection: 600W lightningproof and surge-suppress, 15KV ESD protection
- Terminal resistor: 120R, enabled/disabled via switch
- Transmission Distance: About 1.2km
- Transmission Mode: point-to-multipoint (up to 32 nodes, it is recommended to use repeaters for 16 nodes or more)
- Case Rail-mount ABS case, suitable for 35mm DIN rail
Features:
- Compatible with TTL/RS422 standard, converting the TTL signal into a balanced differential RS422 signal, supporting half-duplex communication
- Compatible with 3.3V ~ 5V TTL signal level, with anti-reverse connection and anti-over-voltage circuit on the power supply side
- Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
- Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, and low power consumption
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, and anti-electrostatic
- Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
Package Includes:
- 1 x Waveshare Rail-mount TTL To RS485 Galvanic isolated Converter, 600W Lightning proof & Anti-Surge, Multi-Isolation Protection
