module is installed in COMM and parameter “bAud” is set to 1, then on-off signal can be inputted, and SV1
and SV2 can be switched by connecting a switch between terminals 3 and 4.

P.S.:0-5 1-5 is not available ,transfer to 0-500mV or 100-500mV
input. 4-20mA input need add resistant 25ohm so that change to
100-500mV, then connect terminal 9 and 8. Terminal 3.4.5 is
for communcation S,S4. L5 is installed then need change bAud
as 0.

SCR Power Module
Note 1: According to the voltage and current of load, choose suitable varistor to protect the thyristor.
Capacitor resistor absorber is needed for inductance load or phase-shift trigger output.
Note 2: SCR power module is recommended. A power module includes two SCRs, is similar to the above
dashed square.
Note 3: K1/K3/K5 is burnt free, easy and reliable.
Note 4： Phase-shift trigger module K5 only supports 200～380VAC power, power frequency must be 50Hz.
