M2M Control C350

The M2M Control C350 is a GSM/GPRS remote control unit especially suitable for wireless monitoring & control, data logging and remote access. The C350 telemetry module combines a freely programmable PLC controller, a data logger with an integrated GSM/GPRS modem. This makes the C350 to a very powerful solution for professional industrial wireless applications like,

  • Remote monitoring and control
  • Security & surveillance
  • Industrial and Building automation
  • Energy management & control
  • Water management                          …   and many more

The unit has an enhanced set of features, including multiple RS-232 and RS485 ports with full MODBUS support (Master / Slave), a CAN Bus and 1-Wire interface as well as 8 digital inputs (4 of them configurable as S0 inputs), 8 outputs, 4 analog inputs and outputs. The onboard inputs and outputs can be expanded completely transparent by adding external MODBUS compatible I/O modules.

The GSM/GPRS based communication supports SMS/PDU messages, IVR (Interactive Voice Response) implementation using Voice/DTMF, CSD data calls as well as an optimized host implemented TCP/IP stack with SMTP, FTP, UDP and MQTT protocol support. The unit supports also our M2M GPRS Gateway middleware solution which enables a bidirectional without the need of fixed IP addresses.

The C350 is fully programmable (IEC 61131-3 ST) and configurable by the user user-friendly M2M Control IDE development environment, either locally via serial port or remotely via GPRS network.

The hardware is based on our reliable X32-architecture (ARM7) and is equipped with advanced power management. The unit has extremely low power consumption and can be powered by batteries or solar panels. The C350 has an industrial grade design, M36 DIN rail mounting and can be powered with wide range of supply voltage (9…36 VDC).
