• D1 firmware offers the most advanced diagnostics including fault logging, event timestamping, and predictive output monitoring – the most advanced firmware in the HLN series

• Flexible output configuration – channels can be set as sourcing or sinking via jumpers

• Short-circuit and load fault protected outputs prevent damage from field wiring faults

• Isolated channels protect the backplane from field wiring faults and surges

• B-grade coating provides basic moisture and dust protection for indoor installations

• Front-panel LEDs for per-channel status, fault, output state, load fault alerts, and predictive maintenance warnings

Competitor Comparison

• vs. DS3800HLNE1B1B (B1/B variant): More channels (16 vs. 8), faster response (<0.3ms vs. <0.4ms), D1 advanced diagnostics (vs. B1) – significant upgrade

Selection Suggestions

• Critical: Confirm the specialized configuration specifics – the “F” variant may have unique timing, sequencing, or fault handling features; obtain the exact firmware specification from the supplier

• Critical: Confirm output configuration (sourcing vs. sinking) – jumper settings must match your field devices

• Critical: Confirm output load current – do not exceed 0.5A per output channel

• Verify your backplane provides both +5V and +24V field power with sufficient current capacity (+24V @ 0.35A)

• Assess channel count – 16 outputs cover larger specialized actuation applications

• Evaluate if D1’s predictive output monitoring, fault logging, and event timestamping are beneficial – particularly valuable for critical protection circuits where post-event analysis and predictive maintenance are essential

• Evaluate environmental conditions – B coating is suitable for clean, dry indoor installations; upgrade to C/D/G/H if needed

• Order mating front connector (p/n may vary – confirm with GE)

• For critical protection applications, purchase with a calibration certificate and 12-month warranty

Precautions

• Critical: The “F” suffix indicates specialized configuration – do not assume standard HLN parameters apply; verify all specifications with the manufacturer or supplier

• Critical: Do not exceed 30V DC or 0.5A per output channel – overvoltage or overcurrent may damage the output transistors

• Critical: Do not short-circuit output channels – outputs are protected but prolonged shorts may cause damage

• Critical: High-speed outputs (<0.3ms) are extremely sensitive to inductive kickback from solenoids – use flyback diodes or surge suppressors across inductive loads to prevent damage; D1’s predictive monitoring helps identify developing faults but does not replace proper suppression

• Ensure field power supply (+24V DC) is stable and within 10–30V DC range

• Use properly sized wiring for output currents – undersized wires may cause voltage drop and overheating

• D1 firmware diagnostics require proper configuration – ensure the load monitoring thresholds and predictive algorithms match your application

• B coating provides basic protection but is not suitable for frequent humidity, salt spray, or chemical exposure – upgrade to C/D/G/H if needed

• Allow 30-minute warm-up before commissioning

• Store in ESD-safe packaging – edge connector is static-sensitive

• Periodically verify output operation every 6 months (critical protection circuits require frequent testing)

• Do not hot-swap – Mark IV backplanes require power-off for insertion/removal

• If replacing a similar specialized board, verify wiring and pinout compatibility – HLNF may differ from other HLN series in pin assignments
