| Parameter | Published value |
|---|---|
| Input | 8–30 VDC; ≤15 mA described as typical |
| Isolation | Optical; ≥2500 Vrms described as typical, test duration unspecified |
| On-state drop / OFF leakage | ≤1.6 Vrms / ≤5 mA, described as typical |
| Current condition | Per-channel figures at 20 °C; exact heatsink and derating required |
| Ambient / humidity | −40 to +70 °C / 5–85% RH; no condensation or icing |
| Protection | IP20 in prose; confirm installed terminal protection |
| AC load voltage / dimensions / mass | Not specified; obtain exact model datasheet |
Selection & installation notes
- Do not infer load voltage from another SSR family. Confirm the actual AC voltage range before selection.
- Two-channel simultaneous operation requires a combined thermal assessment; 2 × 75 A is not an unconditional continuous-load guarantee.
- Non-LED variants are marked custom. Random triggering requires suitable external control and is not an integrated analog power controller.
- Confirm input polarity, heatsink, surge capability, short-circuit protection and tightening torque. OFF-state leakage means the output is not an isolator.
