Product Description
Redundant Power Supply Module AJ35PTF-28DT Mitsubishi Universal model
AJ35PTF-28DT Description
The AJ35PTF-28DT is an integrated compact remote mixed input/output module designed for industrial fieldbus distributed control systems. It integrates 8 channels of DC digital input and 8 channels of transistor output within a single compact unit. The module collects switching signals from on-site sensors and limit switches, and outputs logic control signals to drive DC actuators, solenoid valves, relays and indicator devices via fieldbus communication. Featuring optoelectronic isolation, compact structure and industrial anti-interference performance, it is widely used for decentralized signal acquisition and automatic control in various automated production equipment.
