RYN404E RYN408F is a 4/8 channel multifunctional RS485 relay designed and produced by eletechsup. It adopts a pluggable relay design and uses a very common T73 size relay. In the event of a damaged relay, it can be easily replaced.

Function:

1: Working Voltage DC 12V/24V;
2: Standby current (all relays closed) 4.8MA, 1 relay open 50MA, ...,
3: ''Open'' ''Close'' ''Momentary'' ''Self-locking'' ''Interlock'' ''Delay'' ''Open all'' ''Close all''8 Commands
4: MODBUS RTU command, Write 05/06/15/16, Read 01/03
5: Under the ''Delay'' command ,the maximum delay is 255 seconds;
6 MODBUS commands can be made serial HyperTerminal (serial assistant) OR ''Modbus Poll'' Enter;
7 Set the Slave ID through the DIP Switch: 1-63 ID
8 Set BaudRate via DIP switch : 9600/19200/38400/115200BPS
9 Parity :None(Default)/Even/Odd
