Input terminals

Five digital inputs，one of which can be used set as high speed pulse input, the Max. Frequency can reach 100kHz.

Source PNP or NPN input.

Two analog inputs.

Output terminals

One high speed pulse output (which can be set into open circuit collector output), 0kHz~100kHz square wave output;

one digital output;

one Relay output;

one analog output，0mA-20mA or 0v-10V selectable.

Protection function

motor shortcut detection，input output phase lost protection, over current protection, over voltage protection, low voltage protection, over heat protection, over load protection.
