1. Interface standard: compliant with RS485 standard2. Physical interface: RS485 wiring terminal3. Communication rate: 300-460800bps baud rate (adaptive)4. Support points: each RS485 interface can support up to 32 nodes5. Communication distance: 1200m (9600bps), the higher the communication rate, the shorter the distance6. Working mode: RS485 two-wire (A, B), half-duplex transparent transmission7. Power supply voltage: DC 9-24V8. Transmission medium: ordinary parallel wire/twisted pair9. Size: about 12.1 x 7.2 x 3cmFeatures:1. 8-way RS485 slave port can be extended by one 485 master port with isolation and relay2. RS485 network relay, extension and isolation functions can be realized3. The isolated RS485 interface at the RS485 master port can be connected to RS485 master control devices, and the extended 8-way isolated RS485 interface can be externally connected to various RS485 slave devices, such as RS485 sensors, etc.4. Built-in optoelectronic isolation protection circuit, RS485 master and slave devices are isolated, which can effectively protect RS485 master and slave devices from the damage of ground potential difference between devices, static electricity, surge, which can be applied to industrial environment with high requirements of reliability and safety5. Wide baud rate range, support 300-460800bps wide baud rate communication range (self-adaptive)6. Support 35mm standard rail with rail clips, easy to installSpecification: Package Weight One Package Weight 0.21kgs / 0.47lb One Package Size 15cm * 10cm * 4cm / 5.91inch * 3.94inch * 1.57inch Qty per Carton 146 Carton Weight 30.00kgs / 66.14lb Carton Size 50cm * 50cm * 60cm / 19.69inch * 19.69inch * 23.62inch Loading Container 20GP: 177 cartons * 146 pcs = 25842 pcs40HQ: 412 cartons * 146 pcs = 60152 pcs
