3G Packaged and Socket Modems

Self Managed Modems (DTU)

If you just want to connect serial devices (e.g. RS232) to the internet then please take a look at the linkCONNECT Self Managed Modems.  The linkCONNECT modems include software to actively manage the network conection for optimum performance. 

The cellular modems shown here are from the Siretta quickCONNECT family of advanced M2M modems with GPRS/3G and 4G versions available.

quickCONNECT GPRS/3G/4G modems

The most comprehensive range of 3G UMTS industrial modems? We think so.  3G modems designed with USB, CAN, I2C, GPIO, ADC, GPS, DIN rail, packaged and Socket modems available to buy online.  Designed for OEM and systems integrators, industrial M2M Modems are used in a growing number of applications including asset tracking, process control and many more.

Advances in wireless technology have opened the door to wide ranging machine to machine (M2M) communications, with unprecedented opportunities for smart equipment solutions. Almost any function, measurement or status may now be reported or controlled from either a remote or central location, as if the units were physically connected together. The potential gains in efficiency are vast, and applications in many ways limited only by the imagination.

Siretta offers a range of technically advanced 3G embedded modems and industrial package modems, providing a choice of solutions to meet this exciting market development. Utilising standard interface standards such as serial RS232, RS485, USB and Ethernet, our range of wireless modems, simply put, allow your equipment to access the global communications network, and transmit and receive data and information.

The functionality within the ZETA, ZOOM, ZULU and ZEUS modems is significantly more advanced than the majority of other modem manufacturers today, delivering excellent technical performance and great value for money. Utilising in house design and manufacture, we have taken customer requests and our knowledge of market trends, and turned these into cutting edge, finished product modems for today’s wireless networks.


ZETA 3G Modem with wide input voltage range

A rugged and highly capable 3G/UMTS modem with wide operating voltage range of 5-60V DC makes ZETA ideal for on-vehicle applications including vechicle tracking with the GPS version.  GPIO lines make it easy to remotely monitor the status parameters over the 3G network.


ZOOM 3G Socket Modem with GPS option

The ZOOM 3G socket modem has been designed to easily integrate 3G connectivity using a precertified module requiring little knowledge of modem technology.  Designed as a 'Plug-n-play' module ZOOM can be plugged onto your own PCB with two 20-way headers which include TTL/RS232, GPIO lines and power.


ZULU 3G modem with ARM Cortex M4

ZULU includes a high performance ARM processor which enables a system on modem approach to your product development where your application resides on the modem.  The processor is seperate to the RF processor for maximum performance.  ZULU includes CAN, I2C, ADC and 1-Wire interfaces and includes options for GPS and factory fitted 2000mA rechargable battery.  ZULU is the ultimate platform for remote monitoring and control of equipment with a host of general purpose input/output lines and relay.


ZEUS 3G modem with Ethernet Interface

ZEUS includes all of the great features found in ZULU but USB is replaced by Ethernet connectivity providing access to even more applications.  The ZEUS terminal can be used as a webserver or an Ethernet gateway over the GPRS / UMTS / LTE networks.


Modems with GPS

Most of the products shown are available with integrated GPS as an option.  Look for the -G- option in the part number for GPS or follow the link for more details - Modems with GPS
