Item Specifications
Input terminal
There are five digital input terminals, one of which can be used
as high-speed pulse input. There are two analog input
terminals. AI1 can be used only as voltage input, while AI2 can
be used as voltage or current input. (It can be selected to
keyboard potentiometer input via the jumper.)
Output
terminal
Two digital output terminals
One relay output terminal
One analog output terminal (can be expanded to two), with
optional 0//4mA to 20mA or 0/2V to 10V. It can realize the
output of such physical parameters as setting frequency and
output frequency,while via FM to output 0kHz to 50kHz
square-wave signal. DO3 can also be set to open-collector
output. (AO, FM, DO3 share a channel, making a distinction
via the function selection.)
