Parameters
Parameter Category Specification for UD1015B0CA-2A0
Model Number UD1015B0CA-2A0
Product Type Digital Signal Converter (for DPharp EJA/EJX Transmitters)
Enclosure Type General Purpose Plastic (PPS) Enclosure.
Protection Rating: IP66 (Dust-tight & protected against powerful water jets) / NEMA 4X (Weather & corrosion resistant).
Power Supply Two-wire, 4-20 mA DC loop-powered.
• Operating Voltage Range: 10.5 to 42 V DC (Must be ≤ 32 V DC when using an intrinsic safety barrier).
Output Signal • Primary Output: 4 to 20 mA DC analog, linear with the measured process variable (e.g., pressure, level, flow).
• Load Resistance: 0 to 1050 Ω (with 42 V DC power supply).
• Digital Communication: Supports BRAIN or HART protocol (FSK) superimposed on the 4-20 mA signal.
Input Signal Digital signal from a Yokogawa DPharp EJA or EJX series pressure transmitter.
Display (Optional) This model (-2A0 suffix) typically comes without a built-in local display. A separate indicator can be connected to the dedicated communication port for configuration and readout.
Programming (Configuration) Configured remotely using a BRAIN or HART communicator (handheld device or PC-based software like Yokogawa's "FieldCare" or "PRM").
Performance • Accuracy: The overall measurement accuracy is determined by the connected DPharp sensor. The converter itself adds negligible error.
• Ambient Temperature: -40 to 85 °C (-40 to 185 °F).
Electrical Connections • Conduit Entries: Two 1/2" NPT entries.
• Terminals: Spring-clamp terminals for easy wiring.
Certifications CE, SIL 2 (Functional Safety according to IEC 61508).
Note: The -2A0 suffix denotes a general-purpose unit. For hazardous areas, an intrinsically safe (-1A0) or explosion-proof (-3A0) model would be required.
Primary Applications Used as a remote-mounted interface for DPharp transmitters in various industries for measuring:
• Flow (via orifice plate)
• Level (in tanks and vessels)
• Pressure (absolute, gauge, differential)
• Liquid Density
