PR Electronics 5203B Universal Ex driver for solenoids, acoustic alarms and LEDs. Used anywhere intrinsically safe levels of energy need to be sent to devices located in a flammable atmosphere. The PR 5203B driver has a safety barrier function for the on/off control of solenoids, LEDs and alarms mounted in hazardous areas. The high level of electrical isolation means that input pulses sensed at the 5203B are not electrically connected to the output pulse.

• 3.75 kVac galvanic isolation between input, output and supply
• Digital input per channel for the control of the I.S. output voltage
• Front LED indicates operation status and malfunction
• DIN rail mounting
• Can be mounted in the safe area or in zone 2 / div. 2 and transmit signals to zone 0, 1, 2 and zone 20, 21, 22
• DIP-Switch programming
