Advantages & Features

• Highest channel density in HLN series – 24 high-speed outputs on a single board, more than HLNA’s 8 and HLNC’s 16 channels

• Fastest output response (<0.3ms) – the fastest output response in the entire Mark IV HLN series, designed for the most extreme critical protection logic

• C1 firmware offers 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

• C-grade coating provides moderate moisture and dust protection compared to B – suitable for indoor environments with occasional humidity

• Extended temperature range (-10°C to +65°C) offers more flexibility than B variant

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

• Compatible with Mark IV backplanes and some VIe systems (with adapter)

Application Cases

• Overspeed trip outputs – high-speed solenoid actuation for turbine overspeed protection with maximum trip channels and predictive output monitoring

• Flame detection outputs – fast fuel trip valve actuation for burner management systems across multiple zones with fault logging and event timestamping

• Emergency trip systems (ETS) – critical output actuation for emergency shutdown with highest channel count and post-event analysis

• Turbine start-up sequencing – fast-response output for starter, purge, and auxiliary valves

• Retrofit projects upgrading from B1 firmware for advanced diagnostics, faster response, and improved environmental protection

Competitor Comparison

Selection Suggestions

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

• 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 @ 0.4A)

• Assess channel count – 24 outputs cover the largest actuation applications with the most high-speed outputs

• Evaluate if C1’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 – C coating is suitable for moderate humidity and light chemical exposure; choose D/G/H for more demanding conditions

• 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: 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; C1’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

• C1 firmware diagnostics require proper configuration – ensure the load monitoring thresholds and predictive algorithms match your application

• C coating provides moderate protection but is not suitable for direct salt spray, heavy chemical exposure, or continuous condensation – upgrade to D/G/H for those conditions

• Allow 30–45 minute warm-up before commissioning (C coating affects thermal equilibrium)

• 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 multiple lower-density boards, verify wiring and pinout compatibility – HLND may differ from HLNA/HLNC in pin assignments

• C coating may make component-level repairs difficult – consider board replacement instead of repair
