N4DOJ24 is a 24-channel RS485 relay module designed and produced by eletechsup. It has the following features:
 
1 RS485 address is set by DIP switch, which is convenient for setting and viewing main parameters.
2 Using the standard Modbus Rtu protocol, it can be used in industrial control situations such as computer PLC touch screens.
3 RS485 interface with TVS anti-surge protection, power overcurrent protection, anti-reverse connection protection
4 Using 10A high current relay, it can directly drive most loads
5 NC COM NO three contact outputs, can be used in more situations
6 Two MODBUS RTU commands can be selected through the M0 jumper




Features:

1:DC 12V (12V Version),DC 24V (24V Version)
2.Standby current (all relays closed) 12MA, 1 relay open 40MA, 2 relays open 69MA, 3 relays open 95MA,4 relays open 122MA,5 relays open 149MA,6 relays open 174MA, 7 relays open 200MA,8 relays open 226MA,and so on
3: 24channels 10A relay switch outputs
4: Support standard Modbus RTU command, function code:
Command 1 (default): write 06/16 read/03;
Command 2 (solder M0 jumper): write 05/06/15/16 read 01/02/03/04
5: With hardware Reset function, with TVS anti-surge protection
6 Under the MODBUS command mode, it can support up to 64 devices in parallel
