ENDRESS + Hauser has released the RIA452 industrial display and contactor unit. It is capable of pump control and batching and can accept all process measurement signals including temperature, voltage signals, flow, pressure, level, pH and density.
It can provide loop power if required and is suitable for use in all process industries. Power supply can be 20V-36V dc, or 90V-250V dc according to plant standards. The 92mm x 92mm panel-mounted unit has a seven-digit, 14-segment, multicoloured LCD monitor that displays the measured variable, a large bar graph with over-range and under-range indication, and engineering units.
The system also has digital status inputs for pump monitoring, minimum/maximum value memorised, a linearisation table capability with 32 points (used for converting level measurement into volumetric measurement), and freely programmable engineering units.
A built-in power supply for loop-powered sensors comes as standard, reducing cabling costs. A scalable analogue output offers a range of options for retransmitting the input signal.
An optional pulse output allows transmission of integrated process values such as a 0mA/4mA-20mA flow signal into flow frequency pulses. It can also be used in hazardous areas, considerably expanding its scope of application.
The limit-relay switches can be configured for operating modes that include minimum/maximum safety, alternating pump control and batch function, time control, gradient, and device and sensor malfunction. As a result the RIA452 can deliver a wide range of benefits, including enhanced pump protection, longer pump life and simplified scheduled maintenance.
The Jog Shuttle user-machine interface is an intuitive single button interface that provides simplicity and flexibility and increases user efficiency when programming the unit.
The RIA452 comes with a PC set-up option offering the convenience of being able to back up data from the unit to a PC. Free software enables the initial programming to be done on a PC and then transferred to the unit.
