Chapter 4 Product function introduction

Two-way A-type relay outputs are used, and 3.81mm phoenix terminals are used to lead out normally open

contacts and common points respectively, which can shut off AC 250V/7A and DC 30V/7A at most.

It can be turned on or off to switch input DO to collect signals and report actively. The active report function

of DO supports configuration change report, period, change report + period to realize the device's active report

function;

Periodic report: report the current status according to the configured time period, the time interval can be

1-65535, unit: minute;

Change reporting: that is, when the DO status changes, the DO status is reported once, and the range needs to

be set to a non-zero value.

Support 4-way dry contact acquisition, switch input DI acquisition signal can be turned on or off to actively

report, DI's active reporting function implementation conditions support configuration change reporting, period,

change reporting + period to realize the active reporting function of the device;

Periodic report: report the current status according to the configured time period, the time interval can be

1-65535, unit: minute;

Change reporting: that is, when the DI status changes, the DI status is reported once, and the range needs to be

set to a non-zero value.

It supports 2-channel current signal acquisition, adopts high-resolution ADC, and the acquisition accuracy can

reach 3‰. The factory default configuration is 0-20mA. It supports configuring the acquisition range (register

address is 0x044c) and obtaining the current current signal (floating point) through the Modbus RTU command. :

equipment damage);

Support mode 0x00 (0-20mA): directly output the collected current signal;

Mode 0x01 (4-20mA): The current input device below 3.5mA is used for disconnection detection to output

0mA, and the current greater than 3.5mA is directly output;

Take the Modbus address of the device as 1 as an example (the edge acquisition function needs to be turned

off to use this function, and the following commands are in hexadecimal):

Read the collected current signal (integer):

Send: 01 04 00 64 00 02 30 14
