Product Specification

Advanced Loop-Powered Solenoid/Alarm Driver for Explosive Environments

The MTL 5021 is a cutting-edge single-channel, loop-powered solenoid/alarm driver engineered for Zone 0/IIC hazardous areas, delivering unparalleled precision in actuation of solenoid valves, audible alarms, and simple apparatus across oil & gas, chemical processing, and offshore installations. Unlike traditional galvanic barriers requiring external power, it operates directly from the 4-20 mA loop, reducing panel complexity by 30% compared to multi-channel alternatives like Pepperl+Fuchs KFD2-SR2-EX1. Its ATEX, IECEx, UL, and CSA certifications ensure compliance with global safety standards, while 250 V AC galvanic isolation safeguards against ground loops and voltage surges. With ±1% accuracy and a 10 ms response time, the MTL 5021 enables rapid fault detection for critical processes such as emergency shutdown systems and gas detection alarms. The device supports a 20–35 V DC input range and features a failsafe relay output (25 V DC, 147 mA max) with redundant contacts, ensuring reliable actuation even in unstable power environments. Its loop-powered design (<1.7 W consumption) eliminates auxiliary power needs, making it ideal for remote or space-constrained applications.

Ruggedized Compact Design for Extreme Industrial Conditions

Built to endure extreme environments, the MTL 5021 boasts an IP20-rated housing and -20°C to +60°C operating range, ensuring consistent performance in corrosive or high-vibration settings like mining equipment or offshore platforms. Its temperature-stable circuitry (±50 ppm/°C) minimizes signal drift, while IEC 60068-2-6 vibration resistance protects against mechanical stress during turbine or conveyor belt operations. Unlike Siemens SICL modules requiring external surge protection, the MTL 5021 integrates open/short circuit detection and surge suppression, reducing downtime by 40% in unstable power scenarios. The compact 16 mm DIN rail mount design (110 x 104 x 16.2 mm) and lightweight construction (100 g) optimize panel space and simplify retrofitting into legacy PLC systems. The green LED indicator provides real-time power status, while DIN rail-mounted plug-in terminals cut wiring time by 25% compared to screw-terminal alternatives. With a 10-year operational lifespan and compliance with IEC 61508 functional safety standards, it balances longevity with safety, making it a cost-effective choice for both new installations and legacy system upgrades.

Versatile Connectivity for Smart Industrial Automation

The MTL 5021 redefines adaptability in hazardous area automation, supporting NAMUR/DIN 19234-compliant sensors and bidirectional signal transfer for predictive maintenance systems. Its floating relay output (25 V DC, 147 mA) accommodates diverse receiver inputs, while selectable line fault detection (LFD) ensures signal integrity in long-distance cable runs typical of petrochemical facilities. Although superseded by the MTL5521 for new projects, the MTL 5021 remains fully supported for legacy systems, offering backward compatibility with MTL 5000 series modules and CSA certifications for North American markets. By leveraging its loop-powered architecture and plug-and-play terminals, the MTL 5021 simplifies integration with DCS systems, outperforming Phoenix Contact solutions in scalability and ease of use. This combination of safety, durability, and adaptability positions the MTL 5021 as a trusted solution for industrial automation challenges, particularly in environments demanding reliable solenoid/alarm actuation and hazardous area compliance.
