Successor available

This product is discontinued and will be replaced by the successor model CX320 (or alternatively CX510). The successor model has a current LTE/4G cellular connection and is downward compatible. Applications that have already been implemented and tested can usually be run without any changes.

Low budget – many features

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

The low-cost C305 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 device for demanding and cost-sensitive M2M and IoT applications that require high reliability and easy integration.

Product FeaturesTechnical Data

Integrated mobile communication

The C305 has a 2G/GPRS modem and brings mobile communication 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 Pro Series devices. Thanks to the high-level integration into the development environment (IDE), programming distributed applications is just as easy as programming a single PLC.

Performance and security for edge computing

The C305 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 C310 has 5 digital inputs (4 of which can be configured as S0), 4 digital solid state outputs (36V / 1.5A), 2 flexibly configurable analog inputs and outputs each.
