Model: DigiRail 2A / 4C / 2R / VA

DigiRail Modbus RTU Signal Conditioning Modules

The classic DigiRail family provides an economical, robust way to interface field sensors with supervisory PLCs or SCADA over an RS485 bus. With dedicated modules for analog inputs (2A), high-speed digital counters (4C), power relays (2R), and single-phase AC electrical power parameters (VA), it covers diverse plant telemetry needs.
