M2M Control C450

The M2M CONTROL C450  is designed for a broad range of industrial wireless monitoring & control, data logging and remote access applications - especially suitable for rought environments like,

  • Water management    
  • Energy management & control
  • Agriculture
  • Industrialautomation

The unit is encapsulated in an IP65 classified plastic box with PG cable glands and supports a wide power range from 85..265 VAC / 8..36 VDC.

The C450 telemetry module combines a freely programmable PLC controller, a data logger with an integrated GSM/GPRS modem. The unit has an enhanced set of features, including multiple RS-232 and RS485 ports with full M-Bus, MODBUS support (Master / Slave), a 1-Wire interface as well as 5 digital inputs (4 of them configurable as S0 inputs), 4 relay 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.

Additionally the C450 has a 868 Mhz ISM RF transceiver local wireless communication.

The C450 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 C450 has an industrial grade design, IP67 enclosure can be powered with wide range of supply voltage from 85..265 VAC  to  8..36 VDC.
