With SP3485 and 8bit MCU can realize RS485 signal to control the relay, with appropriate speed width to execute the instruction, baud rate support 4800/9600/19200/38400, efficiency and stability is reasonable.
With optocoupler isolation, using optical signals to transmit electrical signals, to achieve physical isolation of the circuit, the overall stability of the system is higher, to ensure that the implementation of the model of the stability of the transmission, support for 5-32V input voltage.
Optimized relay utility device and circuit, NC/COM/NO type layout relay, can achieve 10ms level of relay rapid continuous response 100,000 times, AgSnO2, AgCdo(<<100ppm) material contacts
Wider load circuits, copper plated and tinned to ensure the voltage and current resistance of the relay load side, Typical load: NC: 5A 277VAC; NO: 10A 250VAC, 10A 28VDC, Maximum switching power: NO 2770VA/280W; NC 1250VA.
Add 120Ω and cut-in/cut-out dip switches, with power indicator and each way of the suction signal indicator, more convenient to use, DIN rail housing for better installation, copper-plated studs, easier to store.
