You require both thermocouple and RTD inputs (12 total channels).
-
You require tachometer feedback .
-
You want predictive thermal modeling and predictive relay maintenance .
-
Your installation operates in extreme environments (-40°C to +100°C) with high vibration.
-
-
Choose the DS3800NPID1D1E if: You need 3A SS and 5A relays with 500-event logging without redundant comms or cyber-hardening.
-
Choose the DS3800NOAA1F1D if: You need 3A SS and 5A relays with RTD support and redundant comms.
Critical Precautions
-
ESD Protection: Always wear a grounded wrist strap.
-
DC Polarity (SS): Solid-state outputs are DC-only and polarity-sensitive .
-
SS Overcurrent: If output exceeds 4.5A, LED flashes red—persistent overcurrent triggers bus fault.
-
SS Voltage Limit: Do not exceed 48VDC.
-
High-Voltage/Current Hazard (Relay): Relay outputs switch 115VAC/8A—lethal. Use proper insulation.
-
Relay Inductive Derating: For inductive loads, derate from 8A to 6A .
-
RTD Wiring: Use 3-wire Pt100 RTDs.
-
Redundant Paths: Both backplane paths must be connected for full fault tolerance.
-
Cyber-Hardening: AES-256 encryption must be enabled via Mark V software.
-
Self-Healing: Enabled by default; disables after 3 resets per channel per 24hrs.
-
No Hot-Swap: Always depower the rack before insertion/removal.
-
CPU Compatibility: Requires Mark V CPU firmware v6.5 or higher for full features.
-
Power Supply: Draws 6.5A on +5V rail—power supply upgrade is mandatory.
