RIA452

Process display with digital output, monitoring and pump control functions

RIA452

• Input with two-wire loop power supply and intrinsic safety option

• Pump control function• Digital output with integration

Specs at a glance:

• Display: 7-digit/14 segment multicolored

• Approval: ATEX II (1) GD [EEx ia] IIC optional

• Standard Dimensions: 96 × 96 mm (3.78" × 3.78")

• Relays: 4 or 8 (optional)

• Function: Linearization, pump control function, integration

• Output: Optional 1 × analog output

Application The RIA452 process display interprets and displays process signals with high resolution and accuracy. It can also be used to automate control tasks via limit values or analogue and digital outputs.

Function Up to eight presettable relays monitor the measured value for any infringement (undershooting/overstepping) of the preset limit values. Further operation modes for the relays are sensor or device errors, batch and pump control functions (e.g. alternating pump control). The scalable analog output offers wide options to transfer the input signal: zoom function, linearization, offset, inverting and signal conversion (conversion in-/output). The optional impuls output offers the possibility to create integrated process values. Simple setting up using a serial interface and PC programme or manually using the configurating dial on the front of the unit.
