Product parameters
1. On-board mature and stable 8bit MCU and MAX485 level conversion chip
2. Communication protocol:support standard Modbus RTU protocol
3. Communication interface:Support RS485 / TTL UART interface
4. Communication baud rate:4800/9600/19200, default 9600bps, support power saving
5. Photocoupler input signal:DC3.3-30V (This input cannot be used for relay control)
6. Output signal:relay switch signal, support manual, flash-off, flash-off mode, the delay base of flash-off / flash-off is 0.1S, the maximum settable flash-off / flash-off time is 0xFFFF * 0.1S = 65535 * 0.1 S = 6553.5S
7. Device address:1-255, default 255, support power-down save
8. Onboard one 5V, 10A / 250V AC 10A / 30V DC relay, which can continuously attract 100,000 times, with diode leakage protection, short response time
9. Onboard relay switch indicator
10. Supply voltage:DC7-24V, with input anti-reverse protection
1. VCC, GND:DC7-24V power input
2. IN, GND:DC3.3-30V optocoupler signal input
3. A +, B-:RS485 communication interface, A +, B- are connected to A +, B-
4. Relay switch signal output
NC:normally closed end, the relay is short-circuited to COM before pull-in, and left floating after pull-in;
COM:public end;
NO:Normally open, the relay is suspended before the pull-in, and shorted to COM after the pull-in.
5. Relay indicator:lit when the relay is on
6. GND, RXD, TXD:TTL level UART communication interface, GND, RXD, TXD are respectively connected to GND, TXD, RXD of the external control terminal
