Allen-Bradley 1783-ETAP1T2SFP Stratix 4100 EtherNet/IP Tap
copper and SFP EtherNet/IP tap
Product Profile
A copper-to-fibre machine connection can use Allen-Bradley 1783-ETAP1T2SFP as a Stratix 4100 EtherNet/IP tap. Its three-port architecture has one RJ45 device port and two SFP network positions, placing a local Ethernet device on a linear or Device Level Ring path that uses optical media beyond the tap.
The tap is a connection and visibility component rather than a general unmanaged switch. Its hardware combines the device port, two 1G SFP positions, 24 V DC input, status indicators, rotary address controls and a DIP switch in one DIN-rail or panel-mounted assembly.
1783-ETAP1T2SFP differs from the all-copper 1783-ETAP3T through its two SFP network positions and single copper device port. The model starts through DHCP without an assigned IP address, accepts its rotary setting at power-up, and uses AOP/EDS device integration as part of the EtherNet/IP configuration path.

Copper-to-fiber path and cabinet fit
System focus
Copper-to-fiber path and cabinet fit
1783-ETAP1T2SFP separates one RJ45 device connection from two SFP network positions. The front device port auto-negotiates 10 Mbps, 100 Mbps or 1000 Mbps and full- or half-duplex operation; the two network positions take 1G SGMII SFP modules for the linear or ring path.
Fit the tap on a DIN rail or panel in either orientation, while reserving 76.2 mm at the front and bottom plus 25.4 mm at the top and sides. The 145.2 x 34.5 x 139.6 mm enclosure outline, bottom DC connector and optical cable bend space must all fit before the device and network leads are dressed.
- 1 auto-negotiating RJ45 device port
- 2 x 1G SGMII SFP network positions
- 145.2 x 34.5 x 139.6 mm envelope
Power, addressing and commissioning sequence
Technical reference
Power, addressing and commissioning sequence
Supply 1783-ETAP1T2SFP from a 24 V DC Class 2/LIM or approved SELV source and terminate the bottom power connector with the specified copper conductor and 0.6 N·m torque. Its 7.25 W maximum consumption and 375 mA maximum current at 24 V DC belong in the cabinet load calculation before the tap is energized.
Commissioning proceeds through mounting, power and Ethernet connection, AOP/EDS registration, IP setup and DIP-switch selection. The tap starts with DHCP enabled and no IP address; rotary-switch settings are read at power-up, while the DLR supervisor role can be selected by DIP switch or software according to the chosen network design.
- 24 V DC; 7.25 W maximum
- AOP/EDS and IP setup
- Rotary setting read at power-up
Frequently Asked Questions
A copper-to-fiber retrofit uses 1783-ETAP1T2SFP; which front connections have distinct jobs?
1783-ETAP1T2SFP has one auto-negotiating RJ45 device port and two SFP positions for the network path. The copper device lead must not be assigned to an SFP position, and the two optical links must not be counted as extra RJ45 ports.
Which transceivers can be fitted to 1783-ETAP1T2SFP without creating an SFP compatibility mismatch?
1783-ETAP1T2SFP uses 1G SGMII SFP communication. The supported modules are 1783-SFP1GSX, 1783-SFP1GLX, 1783-SFP1GEXE, 1783-SFP1GZX and 1783-SFP1GTE.
How much service space must a panel layout reserve for 1783-ETAP1T2SFP?
1783-ETAP1T2SFP needs 76.2 mm clearance at the front and bottom and 25.4 mm at the top and sides. Its 145.2 x 34.5 x 139.6 mm device outline is separate from those clearance allowances.
Before applying 24 V DC to 1783-ETAP1T2SFP, which power-terminal details matter?
1783-ETAP1T2SFP uses a 24 V DC, 18...32 V DC supply and a Class 2/LIM or approved SELV source. Its power connector uses 0.33...3.3 mm² copper conductors with a 0.6 N·m terminal torque.
Why might a connected device link not match the expected speed on 1783-ETAP1T2SFP?
The 1783-ETAP1T2SFP RJ45 device port auto-negotiates 10, 100 or 1000 Mbps and full- or half-duplex operation. The connected device and cable path must be compatible with that negotiated link setting.
What commissioning order avoids an address or device-profile issue on 1783-ETAP1T2SFP?
For 1783-ETAP1T2SFP, complete mounting, power and Ethernet connection, AOP/EDS registration, IP configuration and DIP-switch selection in sequence. DHCP is enabled with no initial IP address, and a changed rotary setting is read after power is cycled.
