Specification

The Mitsubishi FX3S-14MR/DS and FX3S-14MT/DS are high-performance PLC controller modules designed for compact machinery and standalone automation tasks. As part of the FX3S family, they offer a robust 14-point I/O configuration with either relay or transistor output types, making them ideal for small-scale control systems. These units feature a powerful CPU with extensive memory for auxiliary relays (7,680 total, including 384 general and 1,152 EEPROM latched), state relays (4,096 total with 1,000 EEPROM latched), and data registers (8,000 total with 128 general and 972 EEPROM latched). The integrated high-speed counters support 1-phase inputs up to 60 kHz (6 points max) and 2-phase inputs up to 30 kHz (3 points max), ensuring precise speed and position tracking. With a wide range of timers (320 total, including 206 100 ms and 46 10 ms) and counters (235 total, with 36 general and 199 EEPROM latched), the FX3S series provides reliable, maintenance-free operation for demanding industrial environments.
