Smart operator, also known as smart terminal, then the system can automatically (or adjust the instrument) of a given signal and valve position feedback signal, according to the deviation between the two to adjust the output volume of the corresponding control, and replace the low-power servo Amplifier to directly drive the valve, which can be accessed in a variety of regulator or after the computer control system for spare instrumentation。
| ●功能特点 |
| |
| Automatic calibration and manual calibration |
| Automatic to manual switch without disturbance |
| Smart operator can control each analog output with the way all the way off control output; relays forward and reverse control, and all the way analog output for a variety of measurement and control situations |
| Multiple protection, isolation design, anti-interference ability, high reliability |
| Good software platform, with the secondary ability to meet the special features |
| Advanced modular structure, with a powerful instrument chip, feature set, the system is very easy to upgrade |
