Expansion: IO Module, 8 UI, 8 UO
These input/output expansion modules are designed for use with KMC BAC-5900 series controllers. Multiple CAN-5901s can be connected to a controller via a CAN bus. Each CAN-5901 supports up to eight inputs and eight outputs. For example, a BAC-5901 with four connected CAN-5901s could access up to (internal and external) 42 inputs and 40 outputs connected via terminal blocks.
CAN-5901s can be used with the following types of equipment: air handling units, boilers, chillers, pumps, cooling towers, roof top units, heat pump units, fan coil units, unit ventilators, and other HVAC and building automation system equipment.
