The MACX MCR-EX-SL-SD-24-48-LFD is an Ex i solenoid driver specifically designed for managing Ex i solenoid valves in hazardous areas. It operates with a logic input, providing an off-load voltage of 24.3 V and incorporates a current limitation feature set at 48 mA. This device enables line fault transparency and provides error message outputs, maintaining compliance with safety integrity levels up to SIL 3 according to IEC 61508.

Manufactured in Germany, the device is equipped with a screw connection and offers electrical isolation between input and output. It adheres to overvoltage category II and pollution degree 2 standards, ensuring safe operation under various conditions. The nominal supply voltage ranges from 19.2 V DC to 30 V DC, with a maximum switching voltage of 30 V DC and a current limitation threshold above 48 mA, particularly beneficial in line fault detection scenarios.

With a response time of less than 30 ms and capable of sustaining up to 50 mA switching current, the device ensures reliable performance. The intrinsic safety of the output signal is complemented by a status display via a green LED indicating supply voltage. Additionally, it is suitable for a wide ambient temperature range from -20 °C to 49 °C, making it versatile for various operational environments.
