Competitor Comparison

• vs. DS3800HLNE (standard E variant): Faster response (<0.4ms vs. <0.5ms) and B1 diagnostics – significant upgrade

• vs. DS3800HLNA (standard A variant): Specialized configuration, faster response, B1 diagnostics, and B coating – major upgrade

• vs. DS3800HLND1C1C (C1/C variant): HLNE1B1B offers specialized configuration but fewer channels (8 vs. 24), slower response (<0.4ms vs. <0.3ms), and B coating (vs. C) – choose based on specialization vs. density/performance

• vs. DS3800HLNC1B1B (B1/B variant): HLNE1B1B offers specialized configuration but fewer channels (8 vs. 16) – choose based on specialization vs. density

• vs. DS3800HHTB1D1D (relay output): HLNE1B1B offers significantly faster response (<0.4ms vs. 12ms) – better for high-speed protection

• vs. DS3800HLCB (hybrid high-speed I/O): HLNE1B1B is output-only with faster response – better for critical protection outputs

• vs. ABB DSDI series: Similar high-speed discrete capability, but GE offers specialized configuration, B1 diagnostics, and better Mark IV integration

• vs. Siemens 6ES7 series: Similar functionality, but GE offers specialized configuration, faster response, and B1 diagnostics

• vs. Woodward 5437 modules: GE offers specialized configuration and B1 diagnostics

Selection Suggestions

• Critical: Confirm the specialized configuration specifics – the “E” 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 @ 0.3A)

• Assess channel count – 8 outputs are suitable for specialized applications; for higher density, consider HLNC or HLND

• Evaluate if B1’s output current monitoring and load fault detection are beneficial – particularly valuable for critical protection circuits where load integrity is 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 “E” 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 are sensitive to inductive kickback from solenoids – use flyback diodes or surge suppressors across inductive loads to prevent damage; B1’s load fault detection helps identify 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

• B1 firmware diagnostics require proper configuration – ensure the load monitoring thresholds 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 – HLNE may differ from other HLN series in pin assignments
