Compact Controller, 96 x 96 mm

The R2900 temperature controller offers top functionality and flexibility with a minimal installation depth.

The harmonic-free PDPI control algorithm ensures best possible results, and its control parameters are determined by means of self-optimization.

IP 65 protection allows for use in harsh environments. Primary applications include temperature control in plastics processing and packaging machines, oven manufacturing and food processing.
