Parameters Parameter Specification Product Range Modicon TM3 Modular I/O System Module Type High-Speed Analog Input Module Commercial Reference TM3AQ4G Number of Channels 4 Input Signal Type Configurable per channel: Voltage or Current Voltage Ranges 0-10V, ±10V Current Ranges 0-20mA, 4-20mA Resolution 16-bit Conversion Time 50 µs per channel (for all channels: 200 µs max) Accuracy Typically ±0.1% of full scale at 25°C. Input Impedance Voltage: ≥ 1 MΩ; Current: 125 Ω (internal) Maximum Allowable Input Voltage: ±15V; Current: ±30mA Sampling Rate Up to 20 kHz (aggregate for all channels, configurable filtering available). Filtering Configurable low-pass digital filter to balance noise rejection and response speed. Isolation 500 V AC between field side and bus side. Channels are not isolated from each other. Connection Removable screw terminal block. Diagnostic LEDs CH1-4 ERR (red): Indicates a channel-specific error (e.g., overrange). Module STATUS LED (Green/Red for power, communication, and error states). Bus Interface TM3 bus via connection to a TM3 base (e.g., TM5SBER2). Power Consumption From 5V bus: 130 mA (typical). Operating Temperature 0°C to +60°C Storage Temperature -25°C to +70°C Relative Humidity 10% to 95% (non-condensing) Certifications CE, UL, cUL, RoHS compliant.
