A1SJCPU-S3

The Mitsubishi A1SJCPU-S3 MELSEC-A series module is a compact programmable controller module designed for efficient operation. This module features a built-in base unit, a built-in CPU, and a built-in power supply. It accepts input power supply voltage ratings of 100-120 VAC or 200-240 VAC, with an input frequency rating of 50/60 Hz. The A1SJCPU-S3 module supports a maximum apparent power rating of 100 VA, and it supports a rush current rating of 20A for 8ms or less. Its rated output is 5 VDC, 3A, and its overcurrent protection rating is 3.3A or above. The A1SJCPU-S3 module’s efficiency rating is 65% or higher, and it features a “POWER LED” indicator. Its control system employs repeated operation that utilizes the stored program for flexibility. The A1SJCPU-S3 programmable controller module allows I/O control through both a refresh mode and a direct mode. It is programmed with a programming language dedicated to sequence control that combines relay symbol type language and logic symbolic language (MELSAP-II (SFC)). The A1SJCPU-S3 module provides 26 sequence instructions, 131 basic instructions, and 104 application instructions. The module can accommodate up to 8k steps in the main sequence program and main microcomputer program, while the internal microcomputer program capacity is 7k steps (14k bytes). The A1SJCPU-S3 module is equipped with self-diagnostic functions such as watchdog error monitoring, memory error detection, CPU error detection, I/O error detection, and battery error detection functions. It has 256 I/O points and a RAM capacity of 32k bytes, and it can withstand momentary power failures of up to 20 ms. The A1SJCPU-S3 module’s current consumption rating is 0.4A at 5 VDC. The A1SJCPU-S3 module weighs 1 kg or 2.19 lbs.
