Technical overview
- Power input: DC 5 V to 36 V via screw terminals.
- Transmission rate: stable at 300 to 115200 baud.
- Isolation: unibody digital signal and power isolation without external power at the isolated terminal.
- Protection circuitry: onboard TVS against overvoltage, lightningproof with 600 W rating, and ESD protection (15 kV).
- Additional protection: self-recovery fuse and protection diodes against overcurrent and overvoltage.
- RS485 output terminal with optional 120-ohm resistor, enabled via jumper.
- Indicator LEDs: PWR (red), TXD (green), RXD (blue) indicate power, transmit, and receive activity.
- Enclosure: ABS, suitable for 35 mm DIN rail; dimensions 91.6 x 58.7 x 23.3 mm.
Notes and version constraints
- The exact pinout and precise jumper positions must be confirmed on the physical device.
- When using multiple nodes in point-to-multipoint mode, a relay may be required to keep the node count within the 16-node limit.
- Proper grounding connections (SGND/GND) must be verified before commissioning.
- Compatibility with existing RS232 devices should be validated in the target system.
- Protection ratings (e.g., 600 W lightningproof) are based on manufacturer claims and should be independently validated for critical applications.
