Product Overview
The Omron DCN1-2R is the DeviceNet T-branch tap connector for 1 branch line, 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 taps one drop off the trunk cable without cutting the main line. Three orthogonal connectors with screws (XW4B-05C1-V1R-D) carry V+, CAN_H, drain, CAN_L, V- on the standard DeviceNet 5-pole pinout. A standard terminating resistor is fitted on the trunk side, so the tap itself doubles as the end-of-trunk terminator when used at the end of the run.
Rated current between main lines 8 A power / 2 A signal; between main and branch 3 A power / 1 A signal. Insulation 100 MOhm min at 500 VDC; dielectric 500 VAC for 1 minute. DIN rail mounting, vertical orientation, about 103 g, 0 to 55 C ambient. Pairs with the CRT1-OD16 CompoNet slave or DRT2-OD16-1 DeviceNet slave on the downstream drop; the GX-JC06 covers the same junction role on EtherCAT.
Key Features
- DeviceNet T-branch tap for 1 branch line, 3 orthogonal connectors with screws (XW4B-05C1-V1R-D) and standard terminating resistor on the trunk
- Five-pole DeviceNet pinout (V+ red, CAN_H white, drain bare, CAN_L blue, V- black); IDC termination to the thin trunk cable
- Rated current 8 A power / 2 A signal between main lines, 3 A power / 1 A signal main-to-branch; insulation 100 MOhm min at 500 VDC
- DIN rail mount, vertical orientation, side cable entry, about 103 g, 0 to 55 C ambient
- SKU: DCN1-2R
- Series: DCN1-series DeviceNet peripheral taps
Best-Fit Applications
- End-of-trunk DeviceNet drop on a packaging line where the DCN1-2R feeds one remote I/O block and doubles as the 121 Ohm trunk terminator
- Mid-trunk tap on a bottling line DeviceNet run where the DCN1-2R breaks out one branch to a DRT2-ID16S sensor block on the conveyor
- Spare replacement on a DeviceNet retrofit where the original DCN1-2R was lost and the network drawing lists the 3-port body
Buying Checklist
- Pick the DCN1-2R when the cabinet needs a 1-branch DeviceNet tap with orthogonal screw connectors and side cable entry.
- Pick the DCN1-2C instead when the tap needs top cable entry instead of side cable entry on the same 1-branch form factor.
- Pick the DCN1-3NC instead when the network needs a 3-branch tap for more drops at the same physical junction.

FAQ for DCN1-2R
What is the Omron DCN1-2R used for?
It is the DeviceNet T-branch tap for one branch line. Typical uses are end-of-trunk drops on packaging lines, mid-trunk taps on bottling line DeviceNet runs, and spare replacement where the network drawing lists a 3-port orthogonal-connector body.
DCN1-2R vs DCN1-2C - what is the difference?
Both are 1-branch DeviceNet taps with three connectors. The DCN1-2R has side cable entry and orthogonal screw connectors with the cable lock and screw from the top. The DCN1-2C has top cable entry with cable screw and connector screw from the top. Pick the DCN1-2R for side-entry panels; pick the DCN1-2C for top-entry panels.
Does the DCN1-2R include a terminating resistor?
Yes - the DCN1-2R ships with a standard terminating resistor fitted on the trunk side. Use it at the end of the trunk run and remove it if you place the tap mid-trunk with a separate terminator at the far end.
What cable does the DCN1-2R accept?
DeviceNet thin cable only: DCA1-5C10 (gray) or DCA1-5C10-B (blue), outer diameter 7.00 mm, 100 m reel. The IDC contacts in the DCN1-2R pierce the cable jacket without cutting the main line. For thick cable (DCA2-5C10), use the DCA2-5C10 to thin-cable adapter or a different DCN2-series IP67 tap.
