The Omron DRT2-TS04P, also cataloged as the DRT2-TS04P Temperature Input Terminal, operates as a dedicated hardware component for platinum-resistance thermometer signal digitizing within DeviceNet fieldbus systems.

Terminal Hardware Structure

• DRT2: Advanced DeviceNet smart slave terminal platform with integral diagnostic monitoring.
• TS: Temperature sensor input functional hardware block.
• 04: 4-channel analog measurement point capacity.
• P: Platinum resistance thermometer (Pt100/JPt100) sensor element compatibility.

Technical Data Summary

Backplane Integration & Deterministic Data Processing

The DRT2-TS04P provides linear RTD resistance processing without bottlenecking bus communication velocity. Internal firmware logic handles high-precision resistance-to-digital scaling and supports software selection between standard or 1/100 resolution display modes. Optimized data framing enables steady I/O density scaling across master PLC scan cycles, ensuring full firmware flash compatibility for deterministic data cyclic polling over DeviceNet.

Wiring Directives & Installation Rules

DIN-Rail Terminal Mounting

• Latch the terminal assembly securely onto a 35-mm DIN rail or fasten via mounting holes to an enclosure backplate.
• Maintain minimum clearance around the top and bottom vents to ensure unimpeded air circulation for internal thermistor references.

RTD Sensor Lead Termination

• Run 3-wire RTD extension leads in separate shielded conduits to suppress coupled high-frequency industrial noise.
• Set the DIP switches to match the connected sensor type (Pt100 vs. JPt100) and required memory mapping configuration prior to applying bus power.

Frequently Asked Questions

• What sensor elements can be connected to the DRT2-TS04P input channels?

  The module accepts standard platinum resistance thermometers, specifically Pt100 and JPt100 temperature sensors.

• How many network input words are allocated at the master unit for this terminal?

  The terminal allocates 4 input words in standard mode, or 8 input words when the 1/100 high-resolution display mode is active.

• What is the maximum current draw from the DeviceNet communications line?

  The maximum communications current consumption is 70 mA at 24 VDC and 110 mA at 11 VDC.

• What is the ambient storage temperature range for this hardware?

  The terminal can be safely stored in non-condensing environments ranging from -25 deg C to 65 deg C.

• Are hardware DIP switches built into the module for field configuration?

  Yes, integrated DIP switches are provided to set parameters such as sensor type and resolution modes directly on the unit.

• Does the module require an external power supply in addition to bus power?

  Yes, the internal circuitry requires operating power rated at 100 to 240 VAC or 24 VAC/12 to 24 VDC alongside the DeviceNet bus voltage.

• How should cable shielding be handled for long RTD sensor runs?

  Shielded 3-wire cables must be used for RTD runs, with the shield grounded at a single panel ground point to prevent noise loops.

• Can the DRT2-TS04P be installed directly on a DIN rail?

  Yes, the enclosure is equipped with an integral locking clip designed for standard 35-mm DIN track mounting.
