The OptiFlex OF253T-E2 is an advanced equipment controller designed for chilled beams, exhaust fans, unit vents, air curtains, and advanced zone control applications. It supports direct connection and daisy-chain topologies over BACnet/IP or BACnet MS/TP, with integration for devices such as variable frequency drives, electric meters, lighting systems, and Modbus occupancy sensors.
The controller supports customizable control sequences through EIKON graphical programming software, along with Automated Logic ZS sensors, OptiPoint touchscreen interfaces, and OptiPoint smart valves. Dual Ethernet ports support daisy-chain BACnet/IP communications, while built-in Modbus support allows integration with other building systems.
Designed for flexible installation, the OF253T-E2 includes non-volatile memory, a capacitor-backed real-time clock, and support for remote firmware upgrades.
