Model definition
ADM-3142-SC: Single-fiber SC interface, only single-mode optical cable
ADM-3142-FC: Single fiber FC interface, only single mode fiber optic cable
Product description
ADM-3142 can solve the fiber-optic conversion of RS-485/422/232 serial signal of industrial communication system, and solve the interference factor and long-distance transmission problem of RS-485/422/232 serial port signal in complex electromagnetic field environment.
ADM-3000 series serial fiber MODEM can connect terminal unit (RTU) to host (HOST) or distributed data acquisition system (SCADA) controller, and support PLC PPI, MODBUS and other communication protocols.35mm standard rail installation, DC9~48V wide voltage supply, performance, stable operation, fully meet the system communication connection in industrial environment.
Features
1. The fiber interface is a dual-fiber SC port, which does not distinguish between single mode and multimode fiber.
2, with 2 RS-485 or 1 RS-422 or 1 RS-232 interface
3. When applying, one end can be RS-232 and one end is RS-485.
4, zero delay automatic forwarding, asynchronous transmission, point-to-point transmission
5, automatically detect the serial port rate, identify and control the data transmission direction
6, RS-485 maximum communication rate 250Kbps, RS232 maximum communication rate 115.2K
7, the interface provides 600W surge protection, 15KV static protection
8, DC9 ~ 48V wide voltage power supply, to meet the industrial 24V power supply requirements
9, 35mm DIN rail installation
