Applications
- Analog signal acquisition: The module performs voltage, current, resistance, and resistance thermometer measurement across 8 analog input channels.
Key Features
- Analog input channels: 8 channels support current, voltage, resistance, and resistance thermometer measurement.
- Signal ranges: Supported ranges include 1 V to 5 V, -1 V to +1 V, -10 V to +10 V, -5 V to +5 V, -50 mV to +50 mV, -500 mV to +500 mV, 0 to 20 mA, -20 mA to +20 mA, and 4 mA to 20 mA.
- Resolution and accuracy: Resolution with overrange is 16 bit; the operational error limit is 0.5% relative to the input range for voltage, current, and resistance.
- Diagnostics and interrupts: The module has diagnostics, diagnostic alarms, limit value alarms, hardware interrupts, wire-break diagnosis for 1 … 5 V, 4 … 20 mA, R, and RTD, and overflow/underflow detection.
- Measurement connections: It supports voltage measurement, current measurement with 2-wire transducers with external supply and 4-wire transducers, and three-wire resistance measurement with internal cable-resistance compensation.
- Delivery and connector: Delivery includes the infeed element, shield bracket, and shield terminal. The front connector with screw terminals or push-in connection is ordered separately.
