Model Number IDP10-AF1C01F Product Line Foxboro I/A Series Module Type Single-Channel, Isolated Frequency / Pulse Input Conditioner Key Function Conditions and measures frequency or pulse train signals from field devices. Input Specifications Supported Input Signal Pulse or Frequency Input (e.g., from a turbine flow meter, vortex flow meter, or tachometer). Input Type Typically accepts Namur proximity sensor compatible signals or OC (Open Collector) transistor pulse signals. Frequency Range A specific range defined by the "F1C" code (e.g., 0 Hz to 10,000 Hz). The exact range must be verified from the data sheet. Input Voltage Levels Designed for low-voltage pulse signals (e.g., 0-30 VDC). Minimum Pulse Width The module can recognize a minimum pulse duration (e.g., 50 μs). Isolation Channel-to-System (Field-to-Logic): 1500 VAC RMS continuous. Provides protection against ground loops and transients. Output Specifications Output to System A digital value (e.g., totalized pulse count or computed frequency) communicated digitally over the FBI bus to the host controller. Scalability The pulse count or frequency can be scaled within the DCS software to represent engineering units (e.g., liters/min, gallons, RPM). Power Supply Operating Voltage Powered by the +5V and ±15V supplies from the PSS baseplate. Sensor Power May provide a loop power voltage (e.g., 8.2 VDC) for 2-wire Namur sensors. Physical & Environmental Operating Temperature -40°C to +70°C (-40°F to +158°F) Mounting Installs into a dedicated Foxboro PSS series baseplate. Status Indicators (LEDs) Typically includes LEDs for Power (PWR) and Input Status (e.g., pulses detected).
