UK company CIM Advanced Technology Ltd offer the CIM 5300 range of HART multiplexer modules in Eurocard format. The host-side protocol is RS-485 Modbus slave, compatible with most PLC, DCS or SCADA systems. One card carries 4 HART modems, each of which can connect to a point-to-point or multidrop HART loop.
Not switching multiple HART channels on to one modem means you get the fastest possible performance.
