FBE049DC output safety barrier | 4-20mASafety BarrierIt is a DC signal output isolated safety barrier that receives 4mA to 20mA signals from regulators or operators in the safety zone. Through this isolated safety barrier, it reproduces and drives intrinsically safe instruments such as electrical (I/P) converters, valve positioners, various linear actuators, and display devices in hazardous areas. Welcome to all customers.

FBE049DC output safety barrier | 4-20mASafety BarrierOverview
DC signal output isolated safety barrier receives 4mA~20mA signals from regulators or operators in the safety zone, and transmits them through this isolated safety barrier to reproduce and drive intrinsically safe instruments such as electrical (I/P) converters, valve positioners, various linear actuators, and display devices in hazardous areas.
This isolated safety barrier requires independent power supply, with electromagnetic isolation between the power supply input circuit output circuit.
Characteristics
Drive hazardous on-site intrinsic safety equipment, with a load capacity of up to 750 Ω.
4mA~20mA input, isolated output 4mA~20mA.
Modular core design, no need for zero and full adjustment.
Equipped with a working power indicator light.
Intrinsic safety input circuit [Exia IIC, input circuit overcurrent protection.
Plug and unplug terminal block, DIN rail card installation.

Product Application

1. Isolation output of analog current signal to drive on-site intrinsic safety equipment.
2. Equipment connected to the site: valve positioners, electrical converters, and other intrinsic safety display devices.
3. Location of on-site equipment: Zone 0, Zone 1, Zone 2; IIA zone, IIB zone, IIC zone; T4 to T6 danger zone.
4. Connect the safety barrier to the control system (or other unit combination instruments): The AO card of each DCS/PLC outputs current or voltage signals.
