PR Electronics 2 Channel Galvanic Barrier Pulse IECEx ATEX DIN Rail Mount 21.6-300V AC 400mA 5202B4

PR Electronics 5202B4 2 Channel Galvanic Barrier Pulse isolator provides a robust solution for safely transmitting pulse signals from hazardous zones to safe areas. It ensures intrinsic safety by limiting energy levels at sensor inputs, thus preventing ignition risks in flammable atmospheres. The unit incorporates transformer and optical isolation techniques delivering 3.75 kVac galvanic isolation between input, output, and supply circuits. It is designed to measure pulse signals from NAMUR sensors or contacts located in zone 0 or Division 1 hazardous locations.

Equipped with two isolated channels, the 5202B4 module outputs corresponding isolated pulse signals to the controlled area. The galvanic barrier feature ensures the sensor circuit is intrinsically safe, maintaining low energy to prevent hazard even with cable or sensor damage. It complies with international safety standards including IECEx, ATEX, and meets SIL 2 requirements per IEC 61508, assuring high reliability in industrial safety systems.

Installation is facilitated by standard DIN rail mounting and secure screw terminals. The device operates from a wide AC supply voltage range of 19.2 to 300V and supports a maximum safety current of 400mA. It comes with an IP20 rating and functions reliably within ambient temperatures from -20°C to 60°C. The pulse signal type capability supports various process automation and control applications in hazardous chemical, petrochemical, and manufacturing environments.
