PR Electronics 2 Channel Galvanic Barrier, ATEX, IECEx

PR Electronics 5107B HART transparent driver is a safety barrier for current signals and 2-way HART communication transmitted to I/P converters mounted in hazardous area. The 5107B signal conditioner is based on microprocessor technology for gain and offset. The analogue signal is transmitted at a response time of less than 25 ms. Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without distance between neighbouring units, up to 84 channels can be mounted per meter.

• 3.75 kV ac galvanic isolation
• Inputs, outputs and supply are floating and galvanically separated
• 16 V driving voltage on Ex / I.S. output
• Low response time
• Universal supply by AC or DC
•DIN Rail mounting (vertically or horizontally)

The HART protocol is a low speed, digital communications scheme that is carried on a 4 to 20 mA current signal. As 4 to 20 mA loops are commonly used in industry, the HART protocol is easy to implement, easy to use, and easy to troubleshoot. Devices that communicate via HART are popular in many industries.
