Field Configurable Set device ID, register address, decimal places, and scaling at commissioning — no software download required

About This Product

Modbus-Native Display for Industrial Control Systems.

Modbus Displays are industrial-grade LED displays designed specifically for Modbus automation environments — reading register values directly from Modbus RS485 or Modbus TCP/IP networks without intermediate gateways or converters. Connect it to your existing PLC or SCADA network, set the device ID and register address, and live data appears instantly in large bright digits.

Available in 4", 6", 8", and 12" digit heights with 4 to 10 configurable digits per display — suited for any parameter on any Modbus network, from pump station flow rates to SCADA register values. Each display operates as a Modbus slave by default but can be configured as a master to query remote devices when required.

4", 6", 8", and 12" digit heights — choose per installation requirement
Configurable digit count from 4 to 10 per display
Modbus RS485 (RTU and ASCII) and Modbus TCP/IP over Ethernet
Operates as Modbus slave (default) or master — application dependent
Field-configurable device ID (1–247) and register address (0–65535)
16-bit and 32-bit integers, signed and unsigned, with scaling and offset
Decimal point field-settable from 0 to 5 places
Update frequency configurable from 0.1s to 60s per read cycle
Bright red 7-segment LED — high visibility indoors and outdoors

Applications

Where It's Deployed

Typical applications

PLC / SCADA monitoring — display critical register values from PLCs or industrial PCs on the shop floor
Pump station control — show flow rate, pressure, or tank level from Modbus sensors to operators
Gating and water management — display gate position, water level, or flow on a remote display board
Remote monitoring — install displays at multiple points in a distributed control network
Equipment status boards — show equipment health, phase voltage, or load percentage on a single display
Integration with existing Modbus networks — add a display to any Modbus RS485 or TCP/IP network

Data types supported

Modbus registers — 16-bit signed and unsigned integers
32-bit values — combine two consecutive registers for larger numbers
Scaling — multiply by factor and add offset during display (e.g., raw value 450 displayed as 45.0)
Engineering units — technician-selectable units during configuration
