Introduction

NT6800WNR has 6 relays, 8 isolated input. Communicate by rj45 network or Wi-Fi, supports Modbus-TCP.

( NT6800WNDSR: with one DS18B20 ​temperature sensor in addition）​

It can be controlled by PLC / computer / android, suitable for industrial automation, data acquisition systems, environmental monitoring and local control of an electrical and non-electrical parameter, building automation etc.

Key components:  HLK-RM04 serial network module, STM8S105K4T6C, HR911105A, supports secondary development.

How to use network relay made by nitwo tech? It’s easily by 3 steps:

Step 1: Power on the NT6800WNR module with 12-24VDC.

Step 2: Search the SSID of hi link network module rm04 with Wi-Fi dhcp mode.

Step 3: Run android app or .exe file of computer and connect with IP:192.168.16.254 port: 8080

How to setup IP address and Network parameter of hlk-rm04 serial network/wireless module?

HLK-RM04 module working mode can be divided into:

> Serial to Wi-Fi AP
> Serial to Wi-Fi CLIENT
> Serial to Ethernet

Using a web browser for configuring the HLK-RM04 communication mode (Wi-Fi or Lan) and IP easily.

Protocol

• MODBUS-RTU Function:

Coil status (01), input status (02), input and coil registers (03), Force Single Coil (05), Preset Single Register (06).

• Client’s proprietary protocol support also (customized for client of NiTwo tech) example:

CRC 0x68 = 0x55 + 0x01 + 0x12 + 0x00 + 0x00 + 0x00 + 0x00

Operating mode configuration switch description (able to custom as client's need)

S1 OFF: All relay state is off when power on (all open mode).

S1 ON: All relay states before power off can be logged in internal flash memory, for next time power on they will active same as the last time (memory mode).

S2 OFF: Relay is able to active sync with digital DI input, example input 1 availed the relay 1 availed also, only be controlled locally by DI (sync mode).

S2 ON: Relays can be activated either remotely PLC/Computer (MODBUS Master) or locally by digital DI input (pulse mode).

S3 OFF: Relay will active with digital DI input changing (Sync or Pulse mode, optional by dial dip-switch S2) (Linked mode).

S3 ON: Relay is able to configure to no relation with digital DI input, example input 1 availed but the relay 1 doesn’t availed (unlinked mode).

S4 OFF: Accessed by upper Master PLC/Computer (check mode).

S4 ON: Initiative to report the DO DI states to upper Master PLC/Computer (report mode).

SENSOR:             Connect to temperature sensor or temperature humidity sensor

Power-LED:         Power is ON

Wi-Fi-LED:           Blinks when Wi-Fi working mode

Lan-Link-LED:    Blinks when LAN working mode

Mounting and Size

>The buyer should know the product is suitable to the work environment and user or not, use the product correctly and increase the protection measures if need. Please avoid connecting inductive loads like motors, fluorescent lamps, and LED rectifiers etc directly, use AC contactors or intermediate relays if required.
