FBE044-PPTwo in two out distribution safety barrier|Guangzhou FBE044-PPOn site power distribution signal input isolated safety barrier provides isolated intrinsic safety power voltage to transmitters in hazardous areas, and isolates and converts the 4mA~20mA signal generated by the transmitter before transmitting it to the safety zone control system or other intelligent instruments. This isolated safety barrier requires independent power supply, with electromagnetic isolation between the power supply input circuit output circuit. Welcome to all customers.

On site power distribution signal input isolated safety barrier provides isolated intrinsic safety power voltage to transmitters in hazardous areas, and isolates and converts the 4mA~20mA signal generated by the transmitter before transmitting it to the safety zone control system or other intelligent instruments.
　　
Characteristics
Provide a distribution voltage of 16.5V to 28V to the transmitter.
Isolate and transmit the 4mA to 20mA signal of the transmitter.
You can choose 4mA~20mA or 1V~5 output, or other required DC signals. Modular watch core design, no need for zero and full adjustment.
Equipped with a working power indicator light.
[Exia]IICInput circuit overcurrent protection.

Safety barriers are designed to meet explosion-proof requirements by controlling energy. Zener safety barrier, as we know from its name, its main component is the Zener transistor, also known as the Zener diode.

Product Application

1. Provide distribution voltage to the on-site transmitter and isolate and convert the input signal.
2. Devices connected to the site: two-wire or three wire transmitters.
3. Location of on-site equipment: Zone 0, Zone 1, Zone 2; IIA zone, IIB zone, IIC zone; T4 to T6 danger zone.
4. The safety barrier is connected to the control system (or other unit combination instruments): The AI card of each DCS/PLC receives current or voltage signals.
