Parameters
Parameter Category Specification
Model Number UD1015B0CA-2A0
Product Type Digital Signal Converter (for DPharp EJA/EJX Transmitters)
Enclosure & Protection • Material: Plastic (PPS - Polyphenylene Sulfide), corrosion-resistant.
• Rating: IP66 (Dust-tight, protected against powerful water jets) / NEMA 4X (Weatherproof & corrosion-resistant).
• Type: General Purpose (Non-Explosion Proof).
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 connected via an intrinsic safety barrier).
Input Signal Digital signal from a Yokogawa DPharp EJA or EJX series pressure/differential pressure transmitter.
Output Signal • Primary Output: 4 to 20 mA DC analog, linear or square root (user-selectable) with the process variable.
• 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 for configuration and diagnostics.
Display This model (-2A0 suffix) is typically supplied without a built-in local display. Configuration and readout are performed via the communication port using an external handheld communicator or adapter.
Configuration & Diagnostics • Method: Configured remotely using a BRAIN or HART communicator (e.g., Yokogawa's BT200, YHC5150X) or PC-based software (Yokogawa FieldCare, PRM).
• Capabilities: Full access to all transmitter parameters, ranging, damping, diagnostics, and calibration.
Performance • Accuracy: The overall system accuracy is determined by the connected DPharp sensor. The converter itself contributes negligible error.
• Ambient Temperature Range: -40 to 85 °C (-40 to 185 °F).
Electrical Connections • Conduit Entries: Two 1/2" NPT entries.
• Terminals: Spring-clamp terminals for easy wiring.
Safety Certifications • Functional Safety: SIL 2 (According to IEC 61508) when part of a qualified safety instrumented function (SIF).
• Other: CE Marking.
Note: The -2A0 suffix denotes a general-purpose unit. For hazardous areas, an intrinsically safe (-1A0) or explosion-proof (-3A0) model is required.
Primary Applications Remote signal conditioning for DPharp transmitters used in critical measurements across various industries:
• Flow Measurement (via orifice plate, venturi)
• Liquid Level in tanks and vessels
• Differential, Gauge, and Absolute Pressure
• Liquid Density
