The 931S-A2A5N-OP is categorized as a passive isolator and splitter module by Allen Bradley, renowned for its efficiency in signal conditioning applications. This module effectively handles input currents from 4 mA up to 20 mA, with the capability to accommodate a maximum current of 40 mA. The voltage drop across the input is measured at 3.8V, which facilitates proper signal management.
For output, this module generates two signals, both falling within the 4 to 20 mA range. Output signal limits approximate to 31 mA, maintaining operational integrity. Impedance for the output load can be calculated using the equation RL = (UB-12 Volts)/20 mA, which equates to a typical load of 600 ohms at 24 volts.
When it comes to precision, the 931S-A2A5N-OP maintains an output accuracy of 0.1% under typical conditions and up to 0.2% maximum. The temperature coefficient is equal to or less than 150 ppm/K, ensuring minimal drift with temperature variations.
No delays hinder performance; the step response time is less than 20 milliseconds, providing rapid response in fluctuating systems. Additionally, it has a cut-off frequency measured at 30 Hz (-3 dB), allowing it to filter lower frequency signals effectively.
This module operates with supply voltages ranging between 12V DC and 30V DC, utilizing output loop power for functionality. It is designed for a temperature range from 0 °C to +55 °C, making it suitable for various industrial environments. Finally, it is rated for a maximum insulation voltage of 300V, offering safety and performance reassurance in networked systems.
