DFrobot (FIT0827) Industrial 4-Channel Relay Module

Industrial 4-Channel Relay ModuleThe module adopts the standard Modbus RTU protocol, the communication interfacesupports RS485 or RS232 and supports communication baud rates of 2400, 4800,9600, 19200, 38400 (default 9600). Each relay output is independent and can beconnected to different load devices, such as 24V solenoid valves, etc. Both ACand DC devices can be controlled. Each relay output contact is isolated and canset 0-255 device addresses. It can be switched on and off very quickly. Thisindustrial 4-channel relay module allows you to control your electricalequipment only through one computer serial port. It supports DC7-30V widevoltage power supply, optocoupler isolation, four-way switching input, andfour-way relay output. The management and controlling of electrical equipmentcan be completed by a computer, which makes this module able to be widely usedin scenarios like factories, hotels, etc., as well as lighting control instages, homes, cinemas, etc., and can also be used for motor control, productionline control, etc.SpecificationContact Capacity: 10A/30V DC, 10A/250V ACDurability: 100,000 timesData Interface: RS485Rated Voltage: DC 7-30VPower Indicator: 1 red LED indicatorOutput Indicator: 4 red LED indicatorsTemperature Range: industrial grade, -40 85Default Communication Format: 9600, n, 8, 1Baud Rate: 2400, 4800, 9600, 19200, 38400Size: 115x95x41mm / 4.53x3.74x1.61 inch
