N4D4F64 64-Channel Modbus DI/DO Module, DC 7–27V, Isolated Inputs and Darlington Outputs for PLC, Relay and HMI Control

Description:

1 Working voltage: DC 7-27V (9V 12V 24V)

2 Working current: 9-49MA

3 64 optically isolated input ports, NPN input

4 64 Darlington transistor outputs (ULN2803 NPN output)

5 The default command has a variety of output modes: open, close, Momentary, self-locking, interlocking, delay six output modes

6 The input port can remotely control the output port of another board through the RS485 bus

7 MODBUS command 1 supports 03 06 16 function codes, MODBUS command 2 supports 01/02/03/05/06/15/16 function codes

8 The maximum delay of 1 MODBUS command is 255 seconds

9 In MODBUS command mode, up to 64 devices can be used in parallel

10 Input and output two terminal blocks:64P DC3 2.54MM Socket/66P 2.54MM PIN

10 The default baud rate is 9600BPS, you can choose the baud rate by jumper:

1200/2400/4800/19200/38400/57600/115200BPS

11 Sizes (with box):296*115*37MM

12 Weight (with box): 390g

13 Maximum load: The maximum load current of each channel is 300MA, the total maximum load current is 1A


2. Glossary:
Vo: equal to the working voltage DC 7-27V
O1/2/3…64: Output ports, low-level output
''Open'': the output port outputs low level
''Close'': The output port outputs high impedance (floating)
Momentary : Enter the Momentary command, the Rreceiver Relay is Open, delay of 0.5 seconds after, Relay is Close;
Toggle : Enter the Toggle command, the Rreceiver Relay is Open, Enter the Toggle command again, Relay is Close;
Latched : Enter the Channel 1 Latched command, the receiver Channel 1 is Open, the Channel 2 is Close.
Enter the Channel 2 Latched command the receiver Channel 2 is Open, the Channel 1 is Close.
Enter the Channel 3 Latched command the receiver Channel 1 is Close, the Channel 2 is Close.
Delay : Enter the Delay command, the Rreceiver Relay is Open, delay of 0-9999 seconds(MODBUS command is 0-255 seconds )after, Relay is Close;
During the delay, Eter the Close command, immediately close the relay

Output description
The single output load capacity is not greater than 300MA, and the output load capacity of the entire board is not greater than 1A.
1A resettable fuse limits the maximum output current. If you need the total output load to be greater than 1A, please replace the fuse.
