FAQs
Mount the device on a TH35 DIN rail (TH35-15 or TH35-7.5) and secure with the mounting clip. Wire the conductors into the screw terminals using 0.5–2.5 mm² flexible or 0.5–4 mm² rigid conductors as specified, then tighten to 0.6–0.8 N·m. Ensure correct polarity and verify insulation between circuits before power-up.
The relay provides three ranges: 3–30 mA, 10–100 mA, and 0.1–1 A (RMS). Select the range based on the expected load current of the monitored circuit to ensure reliable detection without nuisance trips; for variable loads, start with the middle range and adjust as needed.
Yes. It uses an RMS measuring principle suitable for DC and AC currents. Typical DC applications include 24 V and 48 V systems, while AC applications cover standard 110–130 V control circuits. Verify the DC current levels align with the specified ranges and output ratings.
The device carries CE, UL/CSA, and UKCA certifications (plus CB/CCC declarations). This combination supports regulatory compliance in many regions, including North America and Europe, for electrical relays used in industrial control panels.
Electrical durability is rated at up to 100,000 cycles and mechanical durability up to 30,000,000 cycles, enabling long service life with minimal maintenance. This translates to reduced downtime and lower total cost of ownership in high‑duty applications.
