ADM-2542 Isolated 4-Port RS485 Hub 1 to 4 Repeater Distributor Support RS232 to 485(with Adaptor)

Industrial grade opto isolated 4 port RS485 hubADM-2542Product introductionADM-2542 is a 485 bus split hub (HUB) designed for industrial automation communication, which solves the RS-485 bus star structure networking and solves the RS-485 system requirements in complex electromagnetic environment. Support transmission rate of up to 115.2Kbps, RS-485 interface using isolation technology, 600W surge protection circuit, to provide 1000V isolation voltage, can effectively suppress and ESD protection.The discrimination circuit used in the RS-485 operating mode can automatically sense the direction of the data stream, and automatically switch the enable control circuit to easily solve the delay problem of RS-485 transceiver switching. RS-485 interface transmission distance is greater than 1000 meters, stable performance. Widely used in highway toll collection system, road monitoring system and power collection system, it is a data exchange product with excellent performance and good .performance parameter1 compatible with RS-232 and RS-485 A/EIA standards2, automatically send and receive data: RS232 three wire (TXD.RXD.GND) system communication3 input interface: RS-232 and RS-485 interface4, output interface: 4 port RS-485 interface (T/R1+, -),(T/R2+, -),(T/R3+, -),(T/R4+, -)5, communication rate: 300BPS-115.2KBPS6, work power: DC9-48V, DC12V200MA (MAX) (can be connected to 24V power supply)7, load capacity: each RS485 can connect 32 devices8, communication distance: 1000 meters (1200BPS)9, LED instructions: power supply, data direction indicator10, work mode: asynchronous half duplex (RS-485)11 isolation: isolation voltage 1KVrms /500VDC insulation,quarantineDC/DC module, RS-485 provides 600W surge protection, 15KV ESD protection12 electrical interface: RS232 (DB9), RS485 (8 core industrial terminals), power (2 core industrial terminals)13.
