F4 Process Controller
Saving space with the shortest length behind panel.
0.4" LED display showing SV/PV at a glance.
Front panel protection with NEMA-4/IP65. (The attached packing is    required.)
Higher sampling (100ms) result in higher control performance.
Protect the control object from thermal shock (rapid temperature    change) with the excellent ramp rate facility.
Protect the heating element from excess current during initial
Free GUI PC control software (beta)
