GE DS3800HLND1C1C
Product Name: GE Speedtronic Mark IV HLN Series High-Speed Discrete Output Module
Introduction: The DS3800HLND1C1C is a high-speed logic output module within the Mark IV Speedtronic turbine control system. The suffix “1C1C” indicates 24 high-speed output channels, firmware revision C1, and enhanced environmental protection via conformal coating (improved humidity and mild chemical resistance).
Detailed content
Technical Specifications & Performance Parameters:
- Output Type: 24 VDC discrete (transistor, sourcing or sinking configurable)
- Output Channels: 24 channels
- Output Voltage: 24 VDC nominal (10–30 VDC range)
- Output Current: 0.5 A per channel (short-circuit protected)
- Response Time: < 0.3 ms (fastest in HLN series)
- Isolation: 2500 V RMS optical isolation (channel-to-backplane)
- Power: +5 VDC @ 1.0 A, +24 VDC @ 0.4 A
- Operating Temperature: -10 °C to +65 °C (extended, enabled by C coating)
- Mounting: 6U VME Eurocard, single-slot
Functional Features: C1 firmware offers advanced diagnostics including fault logging, event timestamping, and predictive output monitoring. Per-channel LED status, short-circuit protection, open-wire detection, output current monitoring, and load fault detection.
Structural Characteristics: Conformal-coated PCB for moderate moisture and dust protection. Jumpers allow configuration of sourcing/sinking per channel.
Application Scenarios: Overspeed trip outputs for high-speed solenoid actuation; flame detection outputs for fast fuel trip valve actuation in burner management; Emergency Trip Systems (ETS) for critical protection logic.
Installation & Usage Notes: Compatible with Mark IV backplanes and some Mark VIe systems via adapter. Avoid exceeding 0.5 A per channel. The C-grade coating provides protection against moderate humidity and mild chemicals; suitable for indoor environments.
