Monophase solid state relay with analog input

GT

MONOPHASE SOLID STATE RELAY WITH ANALOG CONTROL

Monophase solid state power relay for resistive loads; “fast-cycling, zero-crossing” firing to
drive double SCR connected in antiparallel; proportional analog control; signal LEDs.

• Analog control input 0- 10VAC, 4- 20mA

• Faceplate protection: IP20

• Power control: Fast-cycling, Zero-crossing mode

• Internal MOV overvoltage protection

• Nominal working temperature 40°C
