The LC-104-W1 is a compact DIN‑rail‑mountable lighting control module designed for smart building and home automation applications. It features a single AC digital input, a thermistor‑type temperature sensor, and four power relay outputs (one Form C and three Form A) that can be configured for seven different DI/DO control modes.
The module communicates via RS‑485 using Modbus RTU or DCON, and can be powered from +10 V to +30 V DC with a typical consumption of 2.4 W. It is built to industrial standards with EMI protection, ESD and EFT ratings, and operates in temperatures from –25 °C to +75 °C. This manual is written in Chinese.
| Input voltage | +10 V ~ +30 V DC |
|---|---|
| Power consumption | 2.4 W (max) |
| Dimensions (W×L×H) | 72 mm × 100 mm × 59 mm |
| Relay output voltage | 250 VAC or 30 VDC |
| Maximum relay load current | 7 A (NO) / 5 A (NC) @ 250 VAC |
| Recommended relay load per channel | ≤ 160 W |
| Communication interface | RS‑485 (Modbus RTU / DCON) |
| Operating temperature range | -25 °C ~ +75 °C |
It supports Modbus RTU and DCON protocols over an RS‑485 interface.
The module provides four relay outputs: one Form C power relay and three Form A relays.
Each relay channel should not be loaded with more than 160 W.
The module operates from –25 °C to +75 °C.
