The Mitsubishi A1SS91 is an analog input/output module engineered with four configurable channels that can be adapted for both input and output tasks. It handles various signal types, including analog voltage or current. When set for voltage, the input range can be ±10V or 0-10V, contingent on configuration choices. Conversely, for current signals, it supports a typical input range of 4-20 mA.
The output functionalities mirror the input capabilities, allowing output configurations of either voltage (±10V or 0-10V) or current (4-20 mA, typical). The A1SS91 module provides impressive resolution options that include both 12-bit and 14-bit selections, ensuring precise data representation. Accuracy is another hallmark, achieving ±0.1% of full scale under standard conditions, making it reliable for critical monitoring tasks.
Sampling frequency is set at approximately 50 ms for each channel, enabling responsive data acquisition. It features channel-to-channel isolation, ensuring that signals do not interfere with one another, maintaining the clarity and accuracy of measurements. The module’s design allows for both DIN rail and direct mounting options, promoting straightforward integration into existing setups. It draws power directly from the PLC base unit, simplifying installation and reducing wiring requirements.
