Q1: What is the difference between SSR-DA and SSR-LA?
SSR-DA is used for ON/OFF switching with 3–32VDC input, while SSR-LA accepts 4–20mA analog input for proportional voltage control.

Q2: What control voltage does SSR-DA support?
The SSR-DA series supports 3–32VDC input control voltage.

Q3: What load voltage does SSR-DA support?
It supports 24–480VAC load voltage.

Q4: Does SSR-DA need a heatsink?
Yes. A suitable heatsink is recommended when the load current is high or the relay works continuously.

Q5: What current ratings are available?
Available models include 10A, 25A, 40A, 50A, 60A, 75A, 80A and 100A.
