◆ Product Description

As a wireless data transmission communication module, CM-GPRS adopts transparent transmission protocol combined with GPRS, and is applied to the automation system with our PLC to realize the wireless connection between the automation system and GPRS network and GSM network. Through the programming software, the PLC can be remotely programmed and diagnosed to realize the program download function. At the same time, the mobile phone user can control the PLC through the SMS short message service, and the CM-GPRS is especially suitable for applications such as remote monitoring of distributed systems.

The CM-GPRS-L can be powered by a lithium battery. Compact and powerful, it meets many requirements of customers.

Applicable fields:

◎Industrial control, remote sensing, telemetry

◎ unattended machine room, warehouse monitoring

◎ pipe network monitoring

◎ Oilfield, coal mine data collection and monitoring

◎ Fault diagnosis of large equipment

◎Other applications requiring wireless data transmission

◆Features

1. The quad-band module is universal and supports Unicom, mobile GPRS network and ordinary mobile phone card (MICRO SIM card).

2, the use of industrial-grade modules, stable performance, quality assurance;

3. The support module automatically restarts when there is no data transmission for a long time (the automatic restart function is disabled when the setting is less than 600 seconds);

4. Data transmission is open and transparent;

5. Standard industrial interface (RS-232/RS-485);

6, support for persistent online mode, with broken line redial and heartbeat function;

7, support local configuration;

8. Support SMS data transmission and reception, support remote SMS setting module parameters (SMS setting parameters support password verification, prevent illegal users from setting parameters and spam SMS interference), and support remote server-side setting parameters (this function can be turned on/off).

★ This product is more convenient to use with Coolmay PLC/PLC integrated machine.

Compact and powerful, it meets many requirements of customers.
