PEPPERL+FUCHS HiD2082 Explosion-proof Isolation Barrier

I. Basic Information
Brand: Pepperl+Fuchs (Germany)
Model: HiD2082 (H-System Series, Intrinsically Safe Dual-Channel Temperature Conversion Isolation Safety Barrier)
Material Code: 475751
Product Type: Dual-channel General Temperature Signal Isolation Converter (Intrinsically Safe Isolation Barrier)
Safety Level: SIL2 (IEC 61508/IEC 61511), ATEX, IECEx Explosion-proof Certification, applicable to 0/1 Zone hazardous explosion-proof scenarios
Installation Method: Requires matching HiD Series Terminal Baseboard Bus Installation, 24VDC Backplane Bus Power Supply, does not support independent rail installation

Core Input Specifications (Hazardous Side)
Supports four types of on-site temperature sensor signal acquisition:
RTD Thermoresistors: Pt100, Pt1000, etc., supports 2/3 wiring method
Thermocouples TC: K, S, B, E, T, J, etc. conventional degrees, built-in cold junction compensation
Millivolt Signal: -100mV to +100mV
Potentiometer Signal: 0.1kΩ to 20kΩ position transmitter signal
Can be independently configured for single channel sensor type, supports 1 input allocation and 2 isolation outputs (signal distributor mode)

 Output Specifications (Safety Side)
Through side DIP coding to switch output types:
Current Output: 4～20mA (source type / sink type bidirectional selectable, compliant with NAMUR NE43 fault protocol)
Voltage Output: 1～5V DC
Three-port Electrical Isolation: Hazardous Zone ↔ Power Supply ↔ Control Room Side, effectively suppressing ground loop interference, preventing on-site surge damage to DCS cards

 Key Functional Characteristics
Line Fault Detection LFD
When sensor breaks or short-circuits, the panel red fault light is illuminated, and the fault is centrally alarmed through the fault bus. Fault can be configured to report over-range / under-range output to the control system.
Flexible Configuration Method
Side DIP coding for quick basic parameter setting, combined with PACTware software to achieve precise configuration of range, sensor type, and fault mode files.pepperl-fuchs.com.
Intrinsically Safe Protection
Limits voltage, current, and energy on the hazardous side, allowing temperature instruments in explosion-proof areas to be directly connected, meeting chemical, oil and gas explosion-proof specifications.
Signal Isolation Anti-interference
High isolation withstand voltage, suitable for power plants, petrochemical strong electromagnetic fields, avoiding temperature signal drift and collection jump.

Electrical and Environmental Parameters
Power Supply: 20.4～30VDC Backplane Bus Power Supply, total machine power consumption ≤ 1.95W
Operating Temperature: -20℃ to +60℃, humidity 5% to 90% RH (no condensation)
Size: 18×114×130mm
