Import Gsm Gprs 3g 4g Sms Controller Alarm — Buy in wholesale FOB from Supplier in China

The Gsm Gprs 3g 4g Sms Controller Alarm is supplied as model s150 and is designed for remote on/off control of machinery via GSM networks. It operates on quad‑band frequencies 850/900/1800/1900 MHz and provides one independent 240 VAC 3 A relay that can be switched by an SMS command. A second alarm‑link relay, also rated 240 VAC 3 A, can be programmed to stay on for 0‑120 minutes after an alarm trigger. The unit accepts 2, 4 or 8 digital inputs, each configurable as normally open or normally closed, and can notify up to three SMS numbers and five dial‑out numbers when an alarm occurs.

Typical GSM remote controllers are housed in IP65‑rated enclosures and operate reliably between - 10 °C and 55 °C, a range that matches most industrial sites. The backup rechargeable battery is sized to sustain operation for 24 hours without mains power, allowing continuous monitoring during outages. Password protection prevents unauthorised access, and two‑way voice communication is enabled through an external microphone and speaker. Programming is performed via a PC configurator connected with a USB cable, a common practice for field devices.

These controllers are widely used for water‑level supervision, motion detection, and equipment shutdown in utilities, building management and remote agricultural installations. Buyers typically integrate the unit with a central monitoring platform and require confirmation of MOQ, lead time and preferred Incoterms before placing an order. The device can also be queried for status or commanded to toggle outputs using simple SMS syntax, reducing the need for on‑site technicians. Prospective importers should request a sample firmware version and verify compliance with local radio regulations.
