Product Overview

The Omron DRT2-DA02 is a DRT2-series DeviceNet smart slave with two analog outputs It is manufactured by Omron Corporation. Hengyixin Automation stocks this I/O expansion unit in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.

Each output is independent and configurable for voltage (0-5 V, 1-5 V, 0-10 V or -10 to +10 V) or current (0-20 mA or 4-20 mA) via DIP switch or the Configurator tool. Resolution is 1/6000 full scale with +/-0.4 percent accuracy at 25 degC.

DIN-rail mount, 150 g, IP20, -10 to +55 degC. Key specs: Outputs 2 analog outputs, voltage or current, independently configurable; Voltage Ranges 0-5 V, 1-5 V, 0-10 V, -10 to +10 V; Current Ranges 0-20 mA, 4-20 mA; Resolution 1/6000 full scale; Accuracy +/-0.4 percent FS at 25 degC; +/-0.8 percent at 0-55 degC; Conversion Cycle 4 ms maximum for both outputs; Output Load Voltage mode >= 1 kOhm; current mode <= 600 Ohm; Isolation Photocoupler between outputs and DeviceNet bus.

Key Features

  • DRT2 Smart DeviceNet slave with 2 independent analog outputs
  • Voltage (0-5/1-5/0-10/+/-10 V) or current (0-20/4-20 mA) per channel
  • 1/6000 FS resolution, +/-0.4 percent accuracy at 25 degC, 4 ms cycle
  • 11 to 25 VDC DeviceNet power, photocoupler isolation, DIN rail
  • SKU: DRT2-DA02
  • Series: DRT2-series Smart DeviceNet slave
  • Voltage: 0-5 V

Best-Fit Applications

  • Driving an inverter speed reference and a control valve positioner on the same DeviceNet node.
  • Sending a 0-10 V setpoint to a temperature controller and a 4-20 mA reference to a pump drive from one slave.
  • Replacing a hardwired 4-20 mA signal panel on a process skid that already runs DeviceNet.

Buying Checklist

  • Choose the DRT2-AD04 instead when 4 analog inputs are needed instead of outputs.
  • Confirm DRT2-OD16 or CRT1-OD16 are added for 16 digital outputs on the same DeviceNet trunk.
  • Choose the DRT2-DA02 when the cabinet already runs DeviceNet and needs 2 analog outputs per node.

FAQ for DRT2-DA02

Can the DRT2-DA02 mix voltage and current outputs on the same slave?
Yes - each output is set independently via DIP switch or the Configurator tool. Output 0 can be 4-20 mA while output 1 is 0-10 V, both active at the same time. The load limits differ per range (1 kOhm minimum for voltage, 600 Ohm maximum for current).
How accurate is the DRT2-DA02 at high temperatures?
At 25 degC the accuracy is +/-0.4 percent full scale. Across the operating range -10 to 55 degC the accuracy is +/-0.8 percent FS. For higher-switch levels over the full temperature range, mount the slave in a temperature-controlled panel or derate the design budget.
What master PLC works with the DRT2-DA02?
Any Omron PLC with a DeviceNet scanner: CJ1W-DRM21 on CJ1 / CJ2, CS1W-DRM21 on CS1, or a built-in DeviceNet port on the NJ501 / NX102 series. Configure with CX-Integrator over USB or Ethernet - the EDS file is on the Omron Europe support site.
Does the DRT2-DA02 need a separate power supply?
No - the slave takes 11 to 25 VDC straight from the DeviceNet cable and runs on that single supply. The DeviceNet scanner or a separate DeviceNet power supply feeds both the slave electronics and the analog output circuit. Total draw is 120 mA at 24 VDC.
