It uses “zero crossover” switching (i.e. it switches when the AC waveform crosses zero to reduce switching noise)
It’s rated for 90 A output current
Input side: 4–32 V DC or 4–16 mA (i.e. can be driven by a DC voltage or current signal)
Output side: 24–600 V AC at 47–63 Hz
Peak Inverse Voltage (PIV) ~ 1600 Vpk
Body-to-body isolation (insulation) ~ 6 kV for 1 minute; input-to-output isolation ~ 8 kV for 1 minute
It has a copper plate of 2 mm thickness (without heat sink) as part of its structure.
Includes LED indicator on the input side (to show when input is active)

-
It is a solid state relay (SSR) / SCR / analog phase‑angle control SSR made by Unison.
-
Input: 4‑20 mA (or also 0–10 V option)
-
Output: 440 VAC, 90 A
-
The “44” in the code likely refers to “440 VAC” rating.
-
The “420” may be part of its internal coding for the design or series.
-
It uses copper (CU2) for conduction / heat paths.
-
It’s designed in a 45 mm “hockey puck” form factor.
-
It has some parameters like PIV, isolation etc (for analogous model): e.g. PIV ~1200 Vpk, isolation input-output ~6 kV for 1 min.
