ABB valve positioner V18345 Electro-Pneumatic Positioner TZIDC
2015-06-24 16:18:53
Description:
The TZIDC is an electronically configurable positioner with communication capabilities designed for mounting to pneumatic linear or rotary actuators. It features a small and compact design, a modular construction, and an excellent cost-performance ratio. Fully automatic determination of the control parameters and adaptation to the final control element yield considerable time savings and an optimal control behavior.……
