The FT1J-4F14KAG-B is an integrated industrial control device combining a 4.3-inch human-machine interface (HMI) with programmable logic controller (PLC) functionality, belonging to the FT1J series. This device features 14 onboard input/output (I/O) points and supports 22 expandable I/O points, meeting control requirements for small to medium-sized industrial applications. Its input section includes 8 universal sink/source inputs, with I12-I13 flexibly configurable as digital inputs (DI) or analog inputs (AI). The output section provides 4 transistor sink outputs and 2 analog outputs, accommodating diverse signal control and actuator drive scenarios.

For HMI performance and design, the device features a 480×272 pixel resolution screen supporting 16 million colors. Paired with a capacitive (PCAP) glass top and black bezel design, it delivers responsive operation and industrial-grade visual aesthetics. Communication capabilities are extensive, supporting multiple industrial protocols including MQTT, EtherNet/IP, Modbus TCP/IP, and BACnet/IP. It also facilitates data exchange via web server, email, Twitter/X, and FTP, enabling efficient data transmission between devices, cloud platforms, and endpoints.

Additionally, the device operates within a wide temperature range of -20°C to +55°C, ensuring reliability in fluctuating industrial environments. It also integrates RTD/thermocouple signal acquisition, PID control, and PWM control capabilities, enabling direct monitoring and closed-loop control of process parameters like temperature and pressure. This makes it widely applicable in industrial scenarios such as automated production lines, small equipment control, and environmental monitoring.
