Ultra Electronics' MX-Series Multiplexers
MX-Series multiplexers can transmit up to 16 channels of bidirectional electrical data over a pair of fiber-optic cables. They feature I/O module selections, including 4-20mA, 0-10 VDC, contact closure and RS-232/485. The I/O modules are available in two- and four-channel versions, and mount on a 35-mm DIN rail. No programming is required, and installation doesn’t require an engineer.
