Low budget – many features

2G/GPRS mobile radio
Control (PLC)
Data Logger
Fault warning device

The C410 combines many functions in one device, from an integrated 2G/GPRS modem and programmable controller (PLC) to a professional data logger and fault indicator. It is the ideal devicefor reliable M2M and IoT applications in harsh environments. The C450 can be supplied with 8..36 VDC. and also supplied with 100..260VAC.

Integrated mobile communication

The C410 has a 2G/GPRS modem, bringing mobile communications directly into your applications. Easy to use for connection to all leading cloud platforms, as fault indicator directly with SMS or voice with IVR (Interactive Voice Response) and DTMF or for communication with other M2M controllers. Thanks to the Integrated Development Environment (IDE), programming distributed applications is as easy as programming a single PLC.

Performance and security for edge computing

The C410 is based on an RTOS real-time core with IEC 61131-3 runtime environment. The 32-bit ST Arm®processor provides more than enough power and memory for your edge-computing applications. AES encryption and a certificate management for all important TCP based protocols (e.g. MQTT, SMTP, TCP/IP Sockets) offer a high security for your communication, e.g. with a cloud.

I/O interfaces

The C450 has 5 digital inputs (4 of which can be configured as S0), 4 relay outputs (5A @250VAC), 4 flexibly configurable analog inputs and outputs each.

Easy communication

In addition to the mobile network connection, the C410 has further local interfaces: RS-232, and 1-wire. This allows easy connection of sensors or other hardware.
