The LC-101H CR is a single-loop lighting control module for smart home and building lighting circuits. Each circuit can be switched on or off remotely over RS-485, locally through a physical switch, or with both methods used separately or combined.The module measures the AC load current on the lighting circuit in the 0 to 5 A range, so the controller can read back the current value over RS-485. This helps identify faulty lights and shows whether the circuit is on or off. The high-power relay is designed to withstand the inrush currents that inductive lighting loads produce when switched, which helps protect the relay and reduce maintenance.No software is needed for basic channel control. When software control is required, the module communicates using Modbus RTU, with the RS-485 address set by hardware.ApplicationsSmart home lighting controlBuilding automation lighting circuitsRemote switching and status monitoring of lighting loads

LC-102H CR is a dual-loop lighting control module for smart home and building automation projects. Each of its two relay outputs can be switched on or off over RS-485, by local physical switches, or by a combination of both, so engineers can choose how control is shared between a central system and wall switches.The module measures AC load current in the range 0 ~ 5 A, so the controller can read back the state of each circuit and identify lamps that have failed or dual-loop circuits that are switched on or off. The relays are high-power types designed to withstand the inrush currents that occur when inductive lighting loads are switched, which helps extend service life and reduce maintenance.Software is not needed for basic operation, and the module can be controlled directly once installed. For system integration, it communicates over RS-485 using Modbus RTU or DCON, with the node address set by hardware and the baud rate configurable in software from 1200 to 115200 bps.ApplicationsSmart home lighting controlBuilding automation lighting circuitsLighting fault monitoring and status feedbackDual-loop lighting with physical switches

The LC-103H CR switches lighting loads directly from a mains-level input, so an engineer can build a basic relay sequence without a remote host controller. Its single isolated AC digital input drives three power relays, each a form A (SPST N.O.) contact rated 16 A at 250 VAC or 30 VDC. Operation is local, and no software is needed to control the relay channels.The module is suited to lamps and electronic ballast loads, with ratings of 40 W at 220 VAC for up to 8 sets of incandescent lamps or 10 sets of LED electronic ballasts. Protection includes 5000 Vrms intra-module isolation, ±2 kV surge and EFT immunity on power, and ±2 kV contact and ±4 kV air ESD.When remote control or status monitoring is needed, the RS-485 port supports Modbus RTU and DCON at 9600 bps, N, 8, 1. Separate addresses can be set for each protocol through hardware configuration. The module is powered from 10 ~ 30 VDC, draws 0.5 W maximum, and mounts on a DIN rail.ApplicationsLighting control in building automationHome automation lighting circuitsSwitching of incandescent lamp and LED electronic ballast loads

LC-223H CR is a DIN-rail lighting control module for dimming ballasts. An isolated analog output (0 to 20 mA, 4 to 20 mA, 0 to 10 V or 1 to 10 V) sets the brightness, while a power relay switches the ballast on and off. Dimming can be driven by a host controller over RS-485 or by local inputs, so it suits both networked and standalone lighting circuits.Two dry contact inputs can step the output through its brightness sequence from 10% to 100% without a remote host. A wet contact input (65 to 240 VAC) supports a conventional wall switch for brightness control. Communication uses Modbus RTU or DCON at 1200 to 115200 bps, and different addresses can be assigned through hardware configuration.Incandescent lamps: 40 W/220 VAC, up to 8 setsLED electronic ballasts: 40 W/220 VAC, up to 10 setsRelay contact rating: 16 A resistive loadIntra-module isolation: 2500 VDC, with 4 kV ESD and 2 kV surge protectionApplicationsDimming of fluorescent lamps and electronic ballastsBuilding automation lighting controlWall switch and dry contact triggered brightness controlHost-controlled lighting via RS-485 networks

LC-305 CR is a 5-channel AC load current measurement module for lighting control applications. Each channel accepts 0 to 5 A AC input at 50/60 Hz and reports the measured load current over a single RS-485 port, so a controller can track the state of each lamp circuit.The module supports Modbus RTU or DCON on its serial port, with baud rates from 1200 to 115200 bps. Hardware-set addresses allow several modules to share one bus. Because the readings are updated every second, the data can be used to flag a failed lamp, spot a lamp that is starting to fade and needs replacing, or detect carbon build-up on relay contacts that may cause them to stick.Single-ended wiring, with accuracy of 3% of FSRMaximum load current of 10 A per module COM point and 5 A per single load at 25°CPowered from 10 to 30 VDC with reverse polarity protectionApplicationsLighting controlLamp failure and fading detectionRelay contact condition monitoringLoad current monitoring on RS-485 networks

The LC-305/DIN CR measures the load current of five AC lighting circuits and reports the readings over RS-485. It suits lighting control installations where engineers need to see whether each lamp is operating normally, rather than discovering a failure on site.Current readings can be used to spot a lamp that is starting to fade and needs replacing, or a relay whose contacts may be becoming sticky from carbon build-up. Communication uses Modbus RTU or DCON, and different addresses can be set through hardware configuration. This DIN-rail variant is supplied for rail mounting, with a dual watchdog and 2000 VDC intra-module isolation.5 AC current inputs, 0 ~ 5 A, single ended, 50/60 HzLoad current measurement accuracy of 3% of FSRRS-485 port supporting Modbus RTU or DCON, 1200 ~ 115200 bpsHardware-set addresses for multi-module networks10 ~ 30 VDC input with reverse polarity protectionOperating range -25 ~ +75 °CApplicationsLighting control: lamp failure and fading detectionRelay contact health monitoring in lighting circuitsLoad current monitoring over RS-485 networks
