Benefits

Configure or Control with Programmable Models

K50 Programmable models provide expanded flexibility and expressive range to communicate status or operating conditions with greater specificity and relevance to each application. Configurable using Banner’s free Pro Editor software or controlled in real time via IO-Link or Modbus, expanded color options, LED animations, and audible tones increase the signaling vocabulary to reflect distinct machine states, guide operator response, or confirm process progress.

Color Selection

LED color is programmable based on machine state, input condition, or system event—providing tailored signaling for each application. Devices offer seven preset colors without configuration, while Pro Editor, IO-Link, or Modbus provide access to up to 14 predefined colors, each of which can be assigned to represent a distinct status, making it easy to adapt signaling behavior with less hardware.

LED Animation

Programmable animations use motion to highlight change, direct attention, or clarify status—helping operators respond faster and more accurately. K50 devices support a wide range of animation types, including flashing, rotating, intensity sweeping, and segment-based effects like chase or fill. These patterns can be tied to machine states, timers, or operator input, helping signal progress or draw attention where it's needed most.

Intensity

Visual and audible intensity can be set independently to match ambient conditions or application demands. LED brightness can be set to low, medium, or high to optimize visibility without distraction. Sound intensity can likewise be adjusted for clarity in quiet or noisy environments. Intensity settings apply globally or per state and may be toggled through input, IO-Link, or Modbus, depending on the model. All adjustments are made in software with no physical changes required.

Audible

K50 Programmable devices with audible capability offer a range of up to 12 tone types depending on model. All audible models provide up to three standard tone patterns that include Continuous/Steady and Pulse/SOS. Select Programmable models offer additional advanced tones that include: three selectable melodies, Strobe, Whoop, Wobble, and more. Each tone is distinct in pattern and character, making it possible to associate specific sounds with particular events, priorities, or response types. Tones can be mapped to states in software and triggered by input or logic conditions, with optional control over playback mode and duration. Configuration is managed through Pro Editor software or controlled dynamically via IO-Link or Modbus.

Display & Control

The K50 I/O Touch Control with Display replaces buttons, potentiometers, and panel displays with a compact, touch-sensitive interface that delivers output control and real-time operator feedback in discrete, pulsed, or analog applications. Discrete models respond to both user input and system signals, enabling interactive control in pick applications. Pulsed models generate selectable PWM or PFM signals to adjust variable devices like Banner’s WLS15 Pro lights. Analog models deliver 0–10 V or 4–20 mA signals for smooth dimming, speed control, or other applications using standard analog input. Integrated RGB LEDs and a 4-digit, 14 segment display use color, animation, and up to 16 characters of scrolling text to show output values, status, and settings—giving operators the information they need, right on the device. Simple configuration via onboard interface or Pro Editor software makes deployment fast and adaptation easy, without adding complexity.

Logic & Control

K50 Programmable devices can be configured to respond to inputs in different ways, controlling both the device's appearance and the output signals it uses to control other equipment. Output behavior can be customized to match the role of the device within the system—whether signaling, acknowledging events, or driving downstream actions. Configurable modes include momentary or latching outputs, normally open or normally closed states, and adjustable on/off delays. Models with analog or PWM/PFM outputs can reflect system values or respond dynamically to logic or touch. Logic and control settings are configurable using Banner’s free Pro Editor software or controlled dynamically via IO-Link or Modbus. Options range from basic on/off control to four-state logic, where each state defines a unique combination of output behavior and appearance.
