Using one 16-bit A/D converter per channel, the MSXB 081 signal-interface (SI) module from Microstar can simultaneously monitor up to eight 4-mA to 20-mA current loops. The device provides both 300 V (peak) of isolation from channel to channel and 700 V (peak) from channel to PC. One can install MSXB 081 SI modules in an industrial enclosure and connect them to a DAP board controlled from a PC, or installed directly into a DAPserver that contains one or more DAPs. From $1395 each.
