Modular 2-Channel GSM Remote Control GRM-10

The GRM-10 device is designed for carrying out simple control and notification processes via the GSM network. The controller features two independent outputs with a maximum load of 16 A / 250 V AC. Two digital inputs allow for integration. With the RS485 interface of the control panels combined with the RXM-01 transmitter, it offers the capability to control the receivers of the EXTA FREE system from a mobile phone using custom SMS messages.

The device is useful in various home automation systems and in industry, where control signals and messages need to be transmitted remotely via the GSM network. Thanks to the CLIP function, the device can be controlled free of charge via the Micro-USB input, and the special software allows for quick and easy configuration of the GRM-10.

The device is particularly recommended for controlling gate drives, providing information about the status of the installation, and remotely controlling power receivers (blinds, lighting, valve drives, etc.). The GRM-10 consists of a 3-module housing and is designed for mounting on a TH-35 rail.

Remote control of electrical devices is achieved through commands (received phone messages, SMS messages) sent from a mobile phone. This enables convenient control of hard-to-reach devices (ventilation, heating, etc.) with two relay outputs and a load capacity of 16 A. The device features optical operating indication (power supply, relay status, GSM modem status) and has low energy consumption, allowing for continuous operation.
