Details

The Model 7716 Process Control Unit (PCU) is a high-speed, fully distributed microprocessor-based controller used with the TAC I/NET integrated network system. The 7716 is designed to connect directly to the controller LAN and works in conjunction with all other controllers and work stations on the TAC I/NET building management system 7700 LAN.

The 7716 supports over 200 addressable points, providing full adaptive Direct Digital Control (DDC), energy management, and process control in a single controller. The 7716 offers I/O expansion through five expansion modules.

The base 7716 controller is a single printed circuit board with a metal baseplate mounting. The baseplate provides keyhole mounting for easy installation within a Schneider Electric Universal Enclosure. All I/O connections to the 7716 are accomplished via plug-on terminal blocks.

Controller Design

The 7716 PCU hardware is based on a monolithic board design, combining processing, memory, communications and field Input/Output (I/O) functions on a single printed circuit board. The controller features quick disconnect terminals, downloadable firmware, an RS-485 LAN port, one or two RS-232 ports, a TTL port for a hand held console, and optional on-board modem drivers. The inherent reliability of this monolithic design is further enhanced with extensive transient protection, automatic self-test features and a fiber optics communications option.
