2080-LC30-16QWB New Micro830 16 I/O Controller 2080LC3016QWB
PRODUCT DETAILS
2080-LC30-16QWB — Micro830 Controller, 16-Point, Relay and Transistor Outputs
The 2080-LC30-16QWB is a Micro830 series programmable controller with 16 onboard I/O points — 10 inputs and 6 outputs — in a mixed output configuration: some relay, some 24V DC transistor. It's a self-contained controller; the CPU, power supply, and I/O all share one housing. No separate power supply module, no backplane to configure. Plug in 24V DC, wire the I/O, and commission.
The Micro830 sits below the CompactLogix family in terms of capacity and features but above basic relay-replacement PLCs in programmability. It supports Function Block Diagram (FBD), Ladder Diagram (LD), and Structured Text (ST) in Connected Components Workbench — Cisco's free programming environment. For standalone machines and small automation cells that don't need a networked controller architecture, it covers the typical I/O and control requirements without the overhead of a larger system.

Onboard I/O Layout
The mixed output configuration — relay and transistor — reflects real application requirements. Relay outputs handle loads that need voltage isolation or AC switching: solenoid valves on a different supply, pilot lights at 120V AC, contactor coils. The transistor outputs are better suited for fast-switching 24V DC loads: proximity sensor lamps, DC solenoids that cycle frequently, or 24V coil contactors where relay wear would be an issue.
The 10 inputs are all 24V DC and accept both sourcing (PNP) and sinking (NPN) sensor wiring. Inputs 0 through 3 also support high-speed counting at up to 100 kHz, making them usable for encoder or pulse input applications without additional hardware.
Expansion and Connectivity
The base controller grows through two expansion mechanisms. Plug-in modules (2080 series) mount directly onto the controller body and add functions like analog I/O, additional serial ports, and specialty inputs. Up to four plug-ins fit on the LC30. For more I/O points, up to four 2085 series expansion modules connect on the controller's right side, each adding up to 16 digital or 4–8 analog points.
Communication options are limited compared to higher-tier controllers. The RS-232/485 serial port supports ASCII, Modbus RTU, and DF1 protocols — enough for basic SCADA connectivity, barcode reader integration, or communication with drives and HMIs over serial. EtherNet/IP requires a 2080-SERIALISOL or similar plug-in; the base controller has no native Ethernet port.
FAQ
Q: Can the 2080-LC30-16QWB communicate with an HMI over serial?
Yes. The onboard RS-232/485 port supports DF1 protocol, which is compatible with PanelView component HMIs and many third-party HMIs. Configure the port for DF1 full-duplex or half-duplex depending on the HMI's requirements.
Q: What's the maximum expansion I/O count?
With four 2085 expansion modules and four 2080 plug-in modules at maximum configuration, total I/O can reach approximately 132 points. The exact number depends on which expansion modules are used, since I/O point counts vary by module type.
Q: Is motion control possible with this controller?
Basic pulse-and-direction stepper motor control is supported using the high-speed transistor outputs and CCW's motion instructions. Closed-loop servo control is not available on the Micro830 platform — that requires a higher-tier controller.
Q: Does the relay output version affect the transistor output performance?
No — relay and transistor outputs operate independently. The relay contacts switch their assigned circuits; the transistor outputs switch 24V DC loads. They share no common circuitry that would cause interaction between the two types.
Q: Can I use the USB port for runtime communication, not just programming?
The USB port supports programming and online monitoring in CCW. It can also be used for firmware updates. It is not designed as a runtime communication port for SCADA or HMI connectivity — use the serial port or an Ethernet plug-in module for that purpose.
