Core Functions
Acquires analog signals (e.g., temperature, pressure, flow, level) by converting continuous signals from sensors (e.g., 4-20 mA current, 0-10 V voltage) into digital quantities for processing and monitoring by the control system.
Supports multi-channel synchronous sampling to ensure real-time consistency of multiple signals, suitable for complex control scenarios requiring precise timing (e.g., multivariate control of distillation columns).
Technical Features
Channel Quantity: Typically 8 or 16 channels (specific to the manual), supporting differential or single-ended input modes.
Signal Types:
Input ranges: Standard industrial signals like 4-20 mA, 0-20 mA, ±10 V, ±5 V, compatible with direct input from thermocouples (TC) and resistance temperature detectors (RTD) when paired with adapter terminal blocks.
Accuracy: Typical accuracy of ±0.05% FS (full scale), with linearization correction and temperature compensation.
Communication Interface: Connects to the main control module (e.g., CP400) via the I/A Series backplane bus (e.g., FOXBUS) with a transmission rate exceeding 10 Mbps.
