Falcon 148 – Digital I/O & Counter Module
Short description: A rugged microcontroller-based 14-channel digital input and 8-channel digital output module with RS485 Modbus RTU communication. Ideal for SCADA, counters, alarms, and industrial supervisory control.
No serial information available.

Key Features
- Microcontroller-based, rugged and reliable design.
- 14 optically isolated digital inputs for potential-free contacts.
- 8 optically isolated digital open collector outputs to drive relays.
- Ideal for SCADA and counter applications (production, revolution, fault, batch counting, bottle filling, etc.).
- RS485 communication with MODBUS RTU protocol; supports multi-dropping.
- DIP switch for baud rate and station ID settings.
- Front panel LED indications for Power, System OK, Tx/Rx, input and output status.
- Reset facility: all 14 counters or individual counter reset via MODBUS.
- All counters stored in battery-backed RAM with >1 year retention.
- Built-in 24VDC, 100 mA excitation supply for field sensors.
- DIN rail mounting for easy panel integration.
