Description:

1. DC 12V (12V Version), DC 24V (24V Version)

2. Standby current (all relays closed) 9-14MA, 1 relay open 41MA, 2 relays open 70MA, 3. relays open 96MA,4 relays open 121MA,

5 relays open 150MA,6 relays open 174MA, 7 relays open 200MA,8 relays open 226MA...

3: 4/8/16 photoelectric isolation Input ports (NPN low level active,8CH have PNP input versions). The input-output relationship can

be set to various association modes through instructions (Self-locking default)/Interlocking/Momentary/Interlocking/Output=Input)

4: RS485 Interface Support standard Modbus RTU command, function code, write 05/06/15/16 read 01/02/03

5 CAN Interface Support Standard Frame /Extended Frame Format (For protocol details, see''CAROA04 CAROB08 CAROC16 CAN COMMAND''

6: With hardware reset function, with TVS anti-surge protection

7:4/8/16 opto-isolated inputs (NPN/PNP), 4/8/16 relay outputs (upgraded relays, more durable)

8 MODBUS commands can be made serial HyperTerminal (serial assistant) OR ''Modbus Poll''Enter;

9 Under the MODBUS command mode, it can support up to 64 devices in parallel

10 RS485 baud rate is 9600BPS. The baud rate can be selected by Conmand 2400 4800 9600 19200 38400 57600 115200BPS

11 The RS485 parity can be none parity, even parity and odd parity

12 The CAN default baud rate is 250Kbps, which can be set to 5-1000KBPS by command

13 The data sending and returning time can be set, with a maximum value of 1000ms

14 Maximum load: 10A / 250VAC, 10A / 125VAC, 10A / 30VDC, 10A / 28VDC, 10A / 12VDC
