Techcon Neosys System Architecture
The Techcon Neosys series is a BACnet/IP-based modular building automation platform designed for intelligent monitoring and control. Its scalable architecture allows controllers, communication modules, power modules, and I/O modules to work together seamlessly — delivering reliable, flexible, and future-ready automation for commercial and industrial buildings.
NS-MCB
Neosys MCB Controller
The Techcon Neosys MCB Controller is the core control unit of the Techcon Neosys series, a BACnet/IP Ethernet-based, freely programmable controller.
Its modular design allows it to operate as a standalone unit or as part of a larger control network.
The functions of the Techcon Neosys MCB Controller include closed-loop control, PID control, temperature and time-based control, and alarm management.
The controller is not equipped with any built-in input or output channels; therefore, it must be used in conjunction with Techcon Neosys series I/O modules to control field devices. Each Techcon Neosys MCB Controller can be connected to up to 32 I/O modules.
