2080-L50E-48QWB — Compact Controller, 48-Point, Relay Outputs, Embedded EtherNet/IP

The 2080-L50E-48QWB is a 48-point compact controller combining 28 onboard 24V DC/AC digital inputs with 20 relay outputs, embedded EtherNet/IP, a USB programming port, and a non-isolated RS-232/485 serial port. Five plug-in slots and support for additional expansion I/O modules give it substantial room to grow beyond its already-high onboard point count, while up to six high-speed counter channels cover applications needing pulse counting or basic motion feedback without a dedicated motion controller.

A 48-Point Controller With Room to Grow

At 48 onboard points, this controller covers a meaningful machine without any expansion at all — 28 inputs handle a substantial sensor count, while 20 relay outputs provide the voltage flexibility to switch AC and DC loads alike directly without interposing relays. Relay outputs specifically suit applications mixing pilot lights, small solenoids, and contactor coils at varying voltages on the same controller, where a transistor-output variant would force a single voltage class across all points.

The five plug-in slots and support for up to four expansion modules mean this controller doesn't box a project in at 48 points — additional analog channels, more digital I/O, or specialty plug-ins (RTD, thermocouple, memory backup) extend capability without forcing a controller swap if the application's scope grows mid-project. Combined with embedded Ethernet for both programming and runtime communication, this puts the controller in a practical middle ground: substantial onboard capability for immediate deployment, with a defined expansion path for the inevitable scope creep that machine projects tend to encounter.

FAQ

Q: Can the relay outputs switch both AC and DC loads on the same controller?

Yes. Relay contacts are voltage-agnostic within their rating — different outputs can switch AC loads while others switch DC loads simultaneously, since each relay operates independently with no shared voltage reference requirement.

Q: How many high-speed counter channels are available, and what are they used for?

Up to 6 channels are supported, used for applications like encoder feedback, flow meter pulse counting, or any process needing to count fast discrete pulses beyond what standard scan-based logic could reliably capture.

Q: Does this controller support analog I/O without an expansion module?

Onboard I/O on this specific configuration is digital only — analog input and output channels are added through plug-in modules in the available plug-in slots rather than being built into the base controller.

Q: Is the RS-232/485 serial port isolated?

No, the embedded serial port on this controller is non-isolated. For isolated serial communication — useful in noisy environments or with variable frequency drives — an isolated serial plug-in module is available as an add-on.
