PR Electronics 9200 Series Solenoid Driver with NPN and PNP Input, Relay Output, 19.2 V dc to 31.2 V dc Supply, ATEX 9203B1A

PR Electronics 9203B1A Solenoid Driver from the 9200 Series is a specialized industrial signal conditioner designed for use in hazardous and intrinsically safe environments. Featuring NPN and PNP input compatibility alongside a relay output, this device supports power supplies ranging from 19.2 V dc to 31.2 V dc and complies with ATEX certification requirements for operation in flammable atmospheres.

The 9203B1A provides 2.6 kV galvanic isolation between input, output, and supply terminals, utilizing transformer and optical isolation technology to ensure high electrical separation and enhanced safety. This isolation prevents electrical connection between input pulses and output signals, which is critical in maintaining intrinsic safety and preventing hazardous energy transfer.

Designed with a compact DIN rail mount and robust screw terminal connections, the device operates within a temperature range of -20°C to 60°C and is rated IP20, making it suitable for indoor industrial control panels. It meets SIL 2 level certification per IEC 61508 standards, ensuring it can be safely deployed in safety instrumented systems.

The unit is configurable through the detachable PR 4501 display, which provides an intuitive interface with a four-line LCD for input signal readout, unit display, analog output or tagging, and relay status indication. Password protection is incorporated into the programming interface to prevent unauthorized modifications, enhancing operational security.

This solenoid driver is engineered for transmitting intrinsically safe signals from non-safe zones to areas such as zone 0, 1, 2, and mining zones (Class I/II/III, Division 1, Groups A-G), making it applicable in petrochemical, pharmaceutical, and mining industry processes requiring explosion-proof equipment.

Galvanic isolation of 2.6 kV ac between input, output, and supply terminals enhances operational safety. Relay output interface for driving solenoids, alarms, and LED indicators in hazardous areas. Supports both NPN and PNP input signal types for broad compatibility.

Configurable via detachable display with password protection for secure programming. DIN rail mounting and screw terminals provide easy installation and maintenance. Certified for SIL 2 safety integrity level and complies with ATEX hazardous area norms.

Operating temperature range from -20°C to 60°C with IP20 enclosure suitable for industrial installations.

This product belongs to the PR Electronics 9200 Series, renowned for reliable and certified signal conditioning products for hazardous environments. Ideal for integration in industrial automation, electrical panels, instrumentation, and process control systems where robust isolation and safety certification are mandatory.
