KOSO KGP5000/KGP5003 smart valve positioner, 4–20 mA, HART 7, Ex d, IP66

KOSO KGP5000 is a digital positioner for control valve pneumatic actuators. It compares the 4–20 mA signal with stem position feedback and holds the valve at the set point. It mounts on single- and double-acting, linear and rotary actuators, including IEC 60534-6 and VDI/VDE 3845, as well as KOSO 5200LA, 6300LA and 5300LA actuators. KGP5003 additionally offers HART 7 and a current position output.

Full autotune finds zero and span and selects PID parameters automatically. The graphic LCD enables setup, status and diagnostics without a communicator. Diagnostics record full stroke count, time at high and low temperature, time at end stop, number of reversals and partial stroke; pressure sensors provide an offline valve signature.

Single/double acting is selected on the pilot relay. Flameproof Ex d IIC T6 enclosure, IP66, weight 3.0 kg (3.3 kg with gauge block).
