The SDV voltage sensor is a voltage sensor suitable for voltage detection/alarming. It has two types of single-action (SDV-F) and dual-action (SDV-D) with overvoltage detection and undervoltage detection (switchable). In addition, it can further detect overcurrent and undercurrent by combining with the current shunt SDV-SH.
This manual describes the Omron SDV series voltage sensors, which detect over‑voltage and under‑voltage conditions for both AC and DC power sources. It covers single‑action (SDV‑F) and dual‑action (SDV‑D) types, with optional timing functions (SDV‑FH, SDV‑FT). The document lists model families, rated voltage ranges, control power options, and safety certifications.
The guide explains how to select the appropriate model, configure the switch settings for polarity, timing, and delay functions, and connect the sensor to the control circuit. It includes wiring diagrams, performance tables, and troubleshooting Q&A for common installation questions. This manual is written in Chinese.
| Rated voltage range | 10 ~ 300 V (AC/DC input universal) |
|---|---|
| Control power voltage options | DC12 V, DC24 V, DC48 V, DC100/110 V, DC125 V, AC100/110 V, AC200/220 V |
| Action time | ≤ 0.5 s |
| Weight (typical) | ≈ 290 g |
| Setting error (single‑action) | + 2 % |
The reset time must be set to at least 5 seconds for proper timing operation.
