Our modular Bulletin 1694 Electronic Circuit Protectors protect the secondary circuits of 24V DC switch mode power supply against short circuit or overload. IO-Link enabled versions provide real-time insight into the status of your control system.
Our modular Bulletin 1694 Electronic Circuit Protectors protect the secondary circuits of 24V DC switch mode power supply against short circuit or overload. IO-Link enabled versions provide real-time insight into the status of your control system. The only 12.5 mm wide modules can be mounted side by side no further accessories required. They come with time-saving push-in terminals. The protection modules are available in single or double channel in the same compact housing. The range comprise fixed current ratings from 1A...10A and an adjustable current version.
What's New?
Provide Real-time Current and Voltage Levels with IO-Link Technology
By choosing IO-Link enabled versions of Bulletin 1694 Electronic Circuit Protectors and Power Modules, you can provide real-time current and voltage levels for any protection channel to your control system. This means you can get early insight to when values are trending out of normal ranges and possible intervene before a fault shuts your process down. IO-Link communications enable remote reset or range adjustment of circuit protection modules.

Bulletin 1694 Temperature Derating Calculator
Considering the ambient temperature during design phase is important. This calculator simulates the current (A) derating in function of the temperature.
Our circuit protectors are a modular system, that consist of power feed modules, protection modules, and power distribution modules. This video shows how the components are mounted on a DIN rail and connected to one another.
IO-Link Technology is a worldwide open-standard protocol that integrates sensors and other field devices into our connected enterprise by connecting the IO-Link enabled device into an IO-Link master module.
Explore this interactive demonstration to compare the performance of Bulletin 1694 Electronic Circuit Protection modules to thermo-magnetic circuit breakers in various fault scenarios on a control circuit.
