Endress+Hauser aims to give users for the processing industry a flexible display/monitor with a uniform set of capabilities, so it has introduced a new unit that will give customers more standard options when changes are needed in the installed applications.E+H calls the RIA452 digital panel-mount display unit a ‘universal unit’ that accepts virtually any measurement signal, and processes that information to provide programmable indication and output for a wide variety of process control applications in pump control and batch functions. The unit features a seven-digit, 14-segment, multicolored LCD monitor, universal inputs and up to eight relay outputs for pump control.
Other features include digital status inputs for pump monitoring, min/max value memory, linearization table capability with 32 points, analog output, and freely programmable engineering units.Numbers and engineering units are displayed in white, bargraph in yellow, over-range and under-range in red and the limit value flags and digital status inputs in green and yellow. The RIA452 can provide power directly to two-wire transmitters, and the scalable analog output offers many different ways of forwarding the input signal, such as zoom function, linearization, offset, inversion and signal conversion. An optional pulse output gives the user the option of transmitting integrated process values. Being intrinsically safe, it can be used in hazardous areas if necessary and it is UL recognized.
In addition, 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 malfunctionThe unit even has a built-in power supply for loop-powered sensors, so extra devices aren't needed, saving costs and wiring. The ability to save the programming and upload it to a PC reduces further programming of additional units for the same application. The initial programming also can be done on the PC with our free software and then transferred to the unit. For security, the programming can be locked with either a hardware key or a software code.A unique design feature called the jog-shuttle operation is a new user-machine interface completely unique to the industry.
It offers great flexibility and simplicity to the user. It’s similar to the 'iDrive' interface on BMWs, if you're familiar with that feature. This is just another way to make more efficient use of the end user's time when programming the unit.The RIA452 is aimed at end users and OEMs of process system skid with applications for food & beverage, pharmaceutical, chemical, petrochemical, power, and mining and metals.
