Model Number IDP10-A22821C-M1V Product Line Foxboro I/A Series® Module Type Single-Channel, Isolated Analog Input Conditioner General Description A microprocessor-based, isolated signal conditioning module for the I/A Series DCS. It provides a single channel of analog input signal conditioning with high isolation. Input Specifications Supported Input Signals • 4 to 20 mA DC (2-wire or 4-wire transmitter) • 0 to 20 mA DC • 0 to 10 V DC • Potentiometer (Ohms) Input Impedance • Current Inputs: 50 Ohms (nominal) • Voltage Inputs: > 1 MΩ Burnout Protection User-selectable via software: • Up-scale (e.g., 22 mA) • Down-scale (e.g., 3.8 mA) • Off Isolation Channel-to-Channel: Not applicable (single channel). Channel-to-System (Field-to-Logic): 1500 VAC RMS continuous. This is a key safety feature. Output Specifications Output to System A digital value representing the input signal, communicated over the FBI bus to the host controller. Resolution Typically 16-bit or higher, ensuring high measurement accuracy. Refresh Rate Dependent on the FBI bus cycle time and system configuration. Power Supply Operating Voltage Powered by the +5V and ±15V supplies from the PSS baseplate. Loop Power (for 2-wire transmitters) Typically 24 VDC nominal, with limited current capacity (e.g., ~30 mA). Environmental & Physical Operating Temperature -40°C to +70°C (-40°F to +158°F) Storage Temperature -40°C to +85°C Relative Humidity 0 to 95% (non-condensing) Mounting Installs into a dedicated Foxboro PSS series baseplate (e.g., PSS11, PSS21, PSS31). Status Indicators (LEDs) Typically includes LEDs for Power (PWR) and Fault (FLT) status. Standards & Compliance EMC Immunity Designed to meet industrial standards for immunity to Electrostatic Discharge (ESD), Radiated RF fields, and Electrical Fast Transients (EFT).
