A1SX81

The Mitsubishi A1SX81 module an input module from the MELSEC A series that was designed for DC input applications. This module comes with 32 input points for supporting extensive connectivity and control options. It supports photocoupler isolation between the input terminals and PC power to ensure reliable and secure operation. The A1SX81 input module operates at a rated input voltage of 12 Volts DC or 24 Volts DC, and this allows it to meet different voltage requirements. The A1SX81 module has input current ratings of about 3 mA at 12 Volts DC and about 7 mA at 24 Volts DC. Up to 60% of its inputs can be powered ON simultaneously at 26.4 Volts DC, and it can efficiently handle multiple input signals. The A1SX81 module’s connection option is a 37-pin D-sub connector. The input points can be used as positive or negative switching inputs, allowing them to be used different control setups. The A1SX81 module also supports potential isolation between process and control, and this isolation is achieved through the use of an optocoupler, providing added safety and security during operation. The A1SX81 digital module is equipped with LED indicators to indicate the status of each input, and this simplifies monitoring and troubleshooting tasks. Its OFF to ON response time and its ON to OFF response time ratings are both 10 ms or less at 24 Volts DC. The A1SX81 module weighs about 0.24 kg and its dimensions are 34.5 x 130 x 93.6 mm (W x H x D). It is a compact and lightweight solution for DC input applications.
