Relay controller series covering 1, 2, 4, 8 and 12-channel RS485 Modbus RTU control, with 50A magnetic latching relay options for high-power lighting and equipment circuits.
The page is written for engineering companies, system integrators, device manufacturers and B2B project procurement teams.
Relay controller projects can be combined with DMX512 lighting control, sunrise and sunset schedules, Modbus integration, MQTT access, platform management and operation logs.
Supported models and firmware can map a remote input, sensor or business event to controller outputs at another site for one-to-one or one-to-many linkage. Applications include water towers and pumps, parking counts, warehouse alarms, irrigation and chain-store equipment.
Select RC/R configurations for high-power switching by actual load and circuit layout. Match circuit scale, communications and local operation separately rather than treating a series name as a load rating.
QC8 provides multi-circuit high-power latching switching. Select by actual loads and circuits; brightness adjustment and energy measurements still require the corresponding dimming and metering devices.

R1 covers one 10A channel. R2 provides two 50A magnetic latching relay channels, while RC4, RC8 and RC12 provide four, eight and twelve such channels. Allocate models by lighting zone, equipment group and cabinet space. This supports both small equipment boxes and larger cinema, exhibition, building or campus lighting cabinets.
The control supply, RS485 bus and local contact inputs form the low-voltage control layer; relay contacts switch the load circuits. Keep output commons, normally open terminals and input commons clearly identified. Load type, inrush, circuit protection and cabinet thermal design determine the installation. A relay rating alone does not define a universal number of lamps or motors.
Local inputs support field operation or contact acquisition, while RS485 Modbus RTU links the unit to a supervisory system. Use cinema arrival and departure scenes, factory work zones or campus cabinet groups as the operating model. The controller executes the outputs; the supervisory system organizes policies and logs. Energy or current acquisition can add a separate operating check.
R1 is a single-channel 10A model. R2, RC4, RC8 and RC12 use the 50A magnetic latching relay specification.
Yes. A PLC can use RS485 Modbus RTU with the protocol for the selected model to control outputs and read status.
Select 4G, Ethernet or RS485 by model. RS485 slaves use a networked host or gateway for platform access.
Select IO count, load characteristics, terminal space and maintenance groups using the specific model drawings.
