xDW-S-4C optoconverters are designed for transmission of two channels of either half-duplex RS485 bus or one four-wire bus RS422. Together with data buses they also enable transmission of one digital input state to relay output in both directions – all that over one singlemode or multimode optical fiber terminated by SC connector (grinding PC). Relay LOCK detects failure of a remote device, optic fiber interruption and supply failure.
