Schneider Electric I2867-A Infinit II Controller

The Schneider Electric I2867-A Infinit II Controller is a compact Andover Continuum terminal controller in the Infinet II family, designed for low-cost, local control of small HVAC equipment such as package units, heat pumps, unit ventilators, and terminal units. It communicates on the Andover Infinet II field bus and can be coordinated with Continuum CyberStation SX 8000 or Infinity SX master, supporting networks of up to 254 Infinet devices. The unit provides five Form A triac-based outputs (ground-referenced) for on/off or pulsed control of lighting, heat, fans, dampers, or valves, plus two Form K analog outputs for 0–10 V control with up to 0.5 A load, all rated for AC loads. On the input side, it offers four universal inputs capable of handling voltage, current, digital, or sensor signals, plus a built‑in Smart Sensor interface featuring a two‑character LED display and a six‑button keypad for local setpoint changes and status checks. Memory and reliability features include non-volatile Flash memory that stores the operating system and programs, an on‑board backing battery to protect runtime data during power loss, and a real‑time clock synchronized over Infinet. The controller is powered from a 24 VAC supply with protective provisions such as a 2 A fuse and MOV surge protection, and communicates via RS-485-based Infinet for robust field‑bus connectivity. Overall, the I2867-A offers a straightforward, scalable solution for distributed control across Andover Continuum installations, delivering dedicated terminal control while remaining compatible with broader Continuum infrastructure.
