Programmable analog input: AI1, AI2: 0V~10V voltage input or 4mA~20mA current input

Open collector output: 1 output

Relay output: 2 outputs

Analog output: 2 outputs, AO1 supports 0mA~20mA current output or 0V~10V voltage output, AO2 supports 0mA~20mA current output

 

Product advantages

• Frequency setting methods: digital setting, analog setting, pulse setting, serial communication setting, multi-speed setting, simple PLC setting, PID setting, etc., which can realize the combination of settings and mode switching sleep Function: Automatic sleep without water, better energy saving effect

• Built-in PID control function

• Simple PLC, multi-stage speed control function: control terminals to achieve up to 16-stage speed control

• Traverse Control Function

• Instantaneous power failure non-stop function

• Speed tracking and restart function: realize smooth start without impact on the rotating motor

• User-Defined Key Function: user-defined multi-function shortcut keys

• Automatic voltage adjustment function: when the grid voltage changes, it can automatically keep the output voltage constant

• Provides multiple fault protection functions: overcurrent, overvoltage, undervoltage, overtemperature, phase loss, overload, and other protection functions
