There are many places, such as remote base station,PBX Switchboard, Water Pump, Router, Server, Gate, Power distribution room, brewery, greenhouse etc.,where are no WIFI coverage. If you want to control the equipments on/off in these places remotely, the GSM relay controllers will be your best option. You can control the devices anywhere anytime via GSM network.

There are three model: CL1-GSM with one relay output, CL2-GSM with two relay outputs, CL4-GSM with 4 relay outputs, each model with white antennat and black antenna for option. If need install the relay controllers in some place without good gsm network signal, suggest to choose the black extended antenna, users can move the black antenna to other places with better gsm signal.

Tips

1. Remote Control, no distance limitation

1. SMS control: All the people who know SMS command and password can send SMS text to control the device.

2. Free Call Control: When the device detects the ring call, the relay 1 will change status, so call control is free of charge. But the call control is only available for first relay ouput.

3. App control: Combine the SMS/Call commands to be APP icons, which is easier to operate. So the APP still communicates with relay controllers via SMS text and phone call of 2G GSM network.

4. Each relay output load: 10A/30VDC, 10A/250VAC

SMS Control Mode

All the people who know SMS command and password can send SMS text to control the device.

Mode 1. SMS on/off command

ON command: SN + PASSWORD + ON ,  can change the relay status to be all ON.

OFF command: SN+ PASSWORD + OFF,  can change the relay status to be all OFF.

Mode 2: COM Command

COM command can control each path of relay status separately.

SMS format: SN + PASSWORD + COM + Relay status code  N or F ( N stands for ON, F stands for Off, X stand for state no change ).

Take CL4-GSM as example:

CL4 has 4 relay outputs. If you want the relay 1 ON, relay 2 ON, relay 3 OFF, relay 4 ON, the password is 0000, edit SMS text: SN0000COMNNFN

Mode 3: T Command: Inching the relay state in short time.

The command is suitable to control electric Door Gate / Garage door.

SMS Text: SN + password +T + inching time (0 to 9)

0 stands for 0.5 second, 1-9 stands for 1 to 9 seconds

For example: a. Send SMS text: SN0000T2, start to inch the relay.

on-----off 2 seconds-----on;

off-----on 2 seconds------off

If the original relay status is ON, it will change to be OFF and held on the OFF state for 2 seconds, then recover to be ON automatically.

If the original relay status is OFF, it will change to be ON and held on the ON state for 2 seconds, then recover to be OFF automatically.

For CL2 and CL4, the SMS command need add state control code C or X of each relay, C stand for excuting the relay inching command, X stand for relay state no change

Mode 4: L Command

Long-time Inching relay switch: Timing control from 001 to 240 Minutes via L Commands. With the function, users can timed-control pond aerator, water pump, routers, server, DC/AC motor and other electrical equipments by SMS

SMS Text: SN + password + L + inching time ( 001 to 240 minutes)

For example. a. Send SMS: SN0000L060

on-----off 60 minutes-----on;

off-----on 60 minutes-----off

If the original relay status is ON, it will change to be OFF and held on the OFF state for 60 minutes, then recover to be ON automatically.

If the original relay status is OFF, it will change to be ON and held on the ON state for 60 minutes, then recover to be OFF automatically.

b. Send SMS: SN0000L030 (on-----off 30 minutes-----on; off-----on 30 minutes-----off)

Note: For CL2 and CL4, the SMS command need add state control code C or X of each relay, C stand for excuting the relay inching timing command, X stand for relay state no change.

Mode 5: Set master number of call control via SMS

Mode 6: Send SMS text: SN + Password + CHECK, can reply the state of each relay.

Mode 7: SMS text change password.

Call Control

When the device detects the ring call, the relay 1 will change status, so call control is free of charge. But the call control is only available for first relay ouput, invalid to relay 2, relay 3, relay 4.

APP control

Combine the SMS/Call control commands to be APP icons, which is easier to operate. So the APP still communicates with relay controllers via SMS text and phone call of 2G GSM network.
