Product Overview

The Omron GRT1-DRT is the GRT1 SmartSlice DeviceNet Communications Unit It is manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports. It acts as the DeviceNet slave for a SmartSlice I/O rack, exposing up to 1024 I/O points (128 bytes input + 128 bytes output) on one node. Up to 64 SmartSlice I/O units stack to its right. The 84 x 58 x 70 mm housing weighs 137 g. Key specs: Network DeviceNet slave, Group 2 Only Slave, predefined master/slave connection set; baud rate auto-detected 125 / 250 / 500 kbps; I/O Capacity 1024 I/O points max (128 bytes input + 128 bytes output); up to 64 SmartSlice I/O units connect to one coupler; Network Power 11 to 25 VDC supplied from the DeviceNet communications connector; Unit Power 20.4 to 26.4 VDC (24 VDC +10 percent / -15 percent); 2 terminals; I/O Power 20.4 to 26.4 VDC (24 VDC +10 percent / -15 percent); 2 terminals; 80 W max per block; 4 A max I/O supply current; Slice Data 0, 2 or 4 bits per.

Key Features

  • GRT1 SmartSlice DeviceNet Communications Unit, exposes up to 1024 I/O points (128 bytes input + 128 bytes output) on one node
  • Up to 64 SmartSlice I/O units stack on the coupler, 80 W max per block, 4 A max I/O supply current
  • Two rotary switches for DeviceNet node address 0 to 63, automatic baud rate detection at 125 / 250 / 500 kbps
  • 4-pole DIP switch for I/O allocation mode, registered table, backup trigger, message communications, 2 KB parameter backup per unit
  • SKU: GRT1-DRT
  • Series: GRT1-series SmartSlice distributed I/O, DeviceNet Communications Unit
  • I/O: 1024 points

Best-Fit Applications

  • DeviceNet drop on a bottling line where the GRT1-DRT stacks up to 64 SmartSlice I/O units for valve banks, level switches and stack lights
  • Retrofit of a hardwired DeviceNet panel where the GRT1-DRT replaces a marshalling panel with a 137 g coupler that does parameter backup via CX-Integrator
  • Spare replacement on a CJ1W-DRM21 DeviceNet master where the GRT1-DRT continues the legacy SmartSlice rack until migration to NX-ECC201 EtherCAT

Buying Checklist

  • Pick the GRT1-DRT for a SmartSlice DeviceNet node that hosts up to 64 I/O units and 1024 I/O points with parameter backup and message communications.
  • Pick the GRT1-CRT instead when the network is CompoNet rather than DeviceNet (CompoNet master units on a CS1W or CJ1W).
  • Pick the NX-ECC201 instead for new builds on EtherCAT with the same SmartSlice-style mounting on the NX-series I/O system.

FAQ for GRT1-DRT

What is the Omron GRT1-DRT used for?
It is the GRT1 SmartSlice DeviceNet Communications Unit. It acts as the DeviceNet slave for a SmartSlice I/O rack and exposes up to 1024 I/O points on one node. Typical uses are DeviceNet drops on bottling lines, retrofit of hardwired marshalling panels, and spare replacement on legacy CJ1W-DRM21 DeviceNet masters.
How many SmartSlice I/O units can the GRT1-DRT serve?
Up to 64 SmartSlice I/O units stack to the right of the GRT1-DRT, exposing up to 1024 I/O points (128 bytes input plus 128 bytes output). The total current budget is 80 W per block at 4 A I/O supply max. Use GRT1-TBR and GRT1-TBL turnback units to extend the rack.
Is the GRT1-DRT still in production?
No. The GRT1-DRT was discontinued on 2024-03-31 per the GRT1-series discontinuation notice and is supported through March 2031. Hengyixin stocks it for the existing install base. For new projects, migrate to the NX-series NX-ECC201 EtherCAT Coupler and NX-OD or NX-ID slice units.
