Channel & Physical Interface Configuration

• Channel Definition: 8 single-ended voltage output channels, shared common ground bus, no inter-channel galvanic isolation, all channels default power-on to 0 V to avoid actuator misstart
• Matching Accessories: Exclusive pairing with cFP-CB-1 screw terminal blocks and cFP-BP-4/cFP-BP-8 backplanes; incompatible with legacy FP-TB series terminal bases
• Status Indicators: 2 global green LEDs (POWER, READY) + 8 independent red channel overcurrent LEDs for per-channel fault localization
• Hot Swap Performance: HotPnP powered hot swapping, no backplane communication downtime or adjacent module signal disturbance during live plugging
• Mechanical Parameters: Single-width compact cFP form factor, bare module weight 115 g, flame-retardant PC housing, IP20 indoor dust protection

Core Analog Output Electrical Parameters

• DAC Resolution: 12-bit monotonic DAC, 4096 discrete output levels, minimum resolution step 2.5 mV, guaranteed monotonicity across full temperature range
• Output Voltage Range: Standard 0–10 V; extended over-range 0–10.2 V for calibrating transmitter span drift and long cable voltage drop
• Current Drive Capacity: Default mode (no external power): ±1 mA per channel; Auxiliary power mode (15–30 VDC input): ±10 mA per channel
• Slew Rate: 0.5 V/μs fast output response, suitable for dynamic valve closed-loop regulation
• All-Channel Update Rate: 200 synchronous updates per second, fixed sampling period with no user-configurable adjustment

Accuracy & Temperature Drift Specifications

• Offset Error @25 ℃: Typical 4 mV, maximum 14 mV across all channels
• Gain Error @25 ℃: Typical 0.2% FS, maximum 0.4% FS full-scale deviation
• Temperature Drift Coefficient: Offset drift 70 μV/℃, gain drift 20 ppm/℃, low drift for long-duration outdoor cabinet operation
• Output Short-Circuit Tolerance: Continuous short-circuit protection to ground, automatic current limiting without permanent channel burnout
• Output Impedance: <0.2 Ω low output impedance, minimizing signal attenuation for 50m shielded analog wiring

Overcurrent & Fault Protection Logic

• Per-Channel Overcurrent Alarm: Independent red LED lights once channel current exceeds rated limit, fault latches until module power cycle reset
• Input Overvoltage Protection: Auxiliary power port withstands -10 V ~ 20 V transient reverse voltage, preventing wiring polarity reversal damage
• Fault Isolation: Single-channel overcurrent will not affect other 7 output channels, avoiding full-system control failure
• Default Safe State: All outputs hold 0 V during backplane communication loss, meeting industrial fail-safe control requirements

Isolation & Safety Compliance

• Isolation Structure: Galvanic isolation between field output side and backplane communication/power bus; zero inter-channel isolation
• Dielectric Withstand Index: 2,300 Vrms 5-second transient impulse withstand, 250 Vrms continuous CAT II field-to-backplane isolation
• Explosive Environment Certification: UL/ATEX/IECEx certified for Class I Div 2 Groups A/B/C/D T4, Zone 2 non-sparking hazardous locations
• Basic Safety Standards: IEC 61010-1, UL 3121-1, CSA C22.2 No.1010.1, Pollution Degree 2 indoor dry environment only
• Altitude Derating: Isolation voltage reduced by 30% when operating above 2000 m altitude

Environmental & Shock-Vibration Reliability

• Operating Temperature: -40 ℃ ~ 70 ℃ full-range rating with no electrical parameter derating
• Storage Temperature: -55 ℃ ~ 100 ℃, 10%–90% RH non-condensing humidity
• Random Vibration: 5 grms 10–500 Hz compliant with IEC 60068-2-64
• Mechanical Shock: 50 g 3 ms half-sine operational shock, 30 g 11 ms transportation shock
• EMC Grade: CE/FCC/C-Tick Class A industrial electromagnetic emission, compliant with EN 61326 immunity standards, shielded wiring mandatory for EMC compliance
