ROD-1M
The ROD-1M Unit is a digital instrument, with double display, for controlling mass flow controllers working with voltage signals (0 - 5 Volts). The two displays give the possibility of monitoring simultaneosly both reading and setpoint values. Value representation, which can be customised, can be displayed in absolute value or as a percentage of full scale. An embedded window alarm subroutine is available in order to halt process with the RODB inner relay. The instrument can work autonomously or, if necessary, can be inserted in a standard sub-rack 19", 3U, which can accept up to 4 units. The presence of a RS-485 serial communication port allows the user to have a full control over the instrument from host PC, to which a maximun of 80 ROD-1M unit can be connected. Safe mode operation allow user to stop process or keep the process working in case of power fault.
