When choosing a programmable relay, module or accessory, it is important to verify the exact order designation and electrical parameters. Variants of the same series may differ in supply, number of inputs, output type, analogue channels and communication.

Typical applications

A programmable GSM / 4G relay allows local control as well as remote communication, depending on the specific variant. It is used for monitoring, status reporting and remote control of processes.

Technical specifications

How to choose the right variant

Compare the supply voltage, number of digital and analogue inputs, number and type of outputs, any analogue outputs, communication options and supported expansion modules. When replacing an existing unit, work from the exact order code and wiring of the original device.

Application design and expansion

When designing the assembly, determine the required number and type of signals, choose a basic unit with reserve, suitable expansion modules and a power supply. For communication with an HMI or higher-level system, verify the available interface and supported protocol.
