N4DVA16 is eletechsup's first differential voltage signal acquisition module. It can collect 0-5V/10V differential voltage signals or ordinary voltage signals, and can also monitor the voltage of 1-16 batteries at the same time.
Features:
1 Working voltage: DC 7-25V (DC 12V/24V)
2 Working current: standby 12MA, working 13-20MA
3 16-channel 0-5V/0-10V differential voltage input
4 Supports standard Modbus RTU instructions, function code: write 06/16, read 03/04
5. With hardware restoration to factory settings function, RS485 with TVS anti-surge protection, anti-reverse power supply and self-restoring fuse
6. In MODBUS command mode, up to 64 devices can be supported in parallel.
7 The default baud rate is 9600BPS. The baud rate can be selected through instructions: 1200 2400 4800 19200 38400 57600 115200BPS.
8. You can choose the parity mode is no parity, even parity and odd parity
9 You can set the data sending return time, the maximum can be set to 1000ms
10 Maximum load: 10A/250VAC, 10A/125VAC, 10A /30VDC, 10A /28VDC, 10A /12VDC
