AI-7028

AI-7028 is capable of measuring and controlling TWO channels of temperature, and every channel can define its own input specification.

AI-7028can either work independently or cooperate with computer or PLC (Programmable Logic Controller). It features:

● Providing up to four channels of configurable inputs, and supporting multiple thermocouple inputs with auto reference junction compensation

and linear voltage (mV) inputs with user defined scale. Every channel has its own digital filtering and can adjust its filtering degree.

● With digital display and physical buttons, which allows data checking and operation setting on module.

● 22.5mm installation width, widely used in occasions that need to save space.

● Special custom LED display, perfect dual 4-digit display in limited space.

● Products designed for ten years life at least and three-year warranty.

● One channel L0 relay output and RS485 communication integrated, convenient for users.

● D7 Terminals for power and communication share one-wire port for plug and unplug.
