DC 12V 24V RES485 Modbus RTU Relay Controller,16CH-IN-NPN 16CH-OUT Programmable Switch Optocoupler Isolator for PLC

1.Description:
 The Optocoupler Isolator for PLC is an expansion board used to increase the number of control objects to meet the control requirements of the system. In MODBUS mode, a maximum of 64 devices can be connected in parallel.

2.Feature:
 1>.It is widely used.
 2>.It is easy to use.
 3>.The maximum load current of each channel is 300mA.

3.Parameter:
 1>.Work Voltage:DC 6.5~30V(7.5V, 9V, 12V ,15V, 24V).
 2>.Work Current:8~50mA.
 3>.Maximum Load:300mA(each channel).
 4>.Work Temperature:-25℃~85℃.
 5>.Work Humidity:0%~95%RH.
 6>.Size:100*72*20mm.

4.Instruction:
 1>.The board has 16 optical isolation input ports (NPN low effective).
 2>.The board has 16 Darlington outputs (ULN2803 NPN output).
 3>.It has 6 commands which are 'on', 'off', 'instant', 'self-locking', 'interlocking' and 'delay'.
 4>.16-way input can remotely control 16-way output of another board RS485 bus (relevant registers need to be set).
 5>.MODBUS RTU instruction supports 03 06 function code (some registers support 16 function code).
 6>.Enter the 'Delay' command. The maximum delay is 255 seconds.
 7>.The MODBUS command can be displayed in the serial port hyperterminal (serial port assistant) or press 'Modbus Poll' and 'enter'.
 8>.In MODBUS mode, a maximum of 64 devices can be connected in parallel.
 9>.The default baud rate is 9600BPS. Baud rate can be selected(2400 4800 9600 19200BPS).

5.Application:
 1>.PLC IO expansion board.
 2>.Smart home.
 3>.PTC camera.
 4>.Safety monitoring.
 5>.Recognition system.
 6>.Webcam.
 7>.LED lamp driver.
 8>.Automatic curtain control.

6.Package:
   1 pcs DC 12V 24V RES485 Modbus RTU Relay Controller.
