(2) Ext Fiber Terminal Block to ST Multimode Async 232/422/485

RS-232 signals are supported up to 115.2 kbps; RS422 or RS-485 signals are supported up to 460.8 kbps. Fiber optic cabling makes it immune to EMI/RFI and transient surges. It's ideal for data communications near heavy electrical equipment and other electrical or radio interference! Replaces converters and isolators when you connect remote equipment. Modbus ASCII or RTU compatible. Automatic Send Data Control eliminates the need for driver software. Removable terminal blocks. Conveniently mounts on an optional DIN Rail. Communicate signals in a point-to-point or ring topology. Communicate signals in a point-to-point or ring topology. Ideal for fiber applications that use different interface protocols. Extended ambient operating range Data-derived or RTS transmit/receive switching (RS-485). Indicator LEDS monitor signal and power. Three-way isolation, 2000-V input/output. Enables any two async serial devices to communicate half- or full-duplex over two multimode ST fibers at distances up to 2.5 miles (4 km).
