NEMA TS-2 BUS INTERFACE UNIT

The BIU-700 Bus Interface Unit (BIU) performs the interface between Port 1 of the Controller Unit and the Loop Detector Racks, Terminals and Facilities, and other devices in a NEMA TS-2 Cabinet Assembly. Its functions include controlling load switch outputs, detector resets, communicating with Inductive Loop Detectors and other devices, and the conditioning and conversion of Terminals and Facilities and Loop Detector call inputs for the Controller Unit.

Each EDI BIU-700 is put through a vigorous three part Total Quality Assurance program and tested under the extreme environmental conditions experienced on the street. It is this commitment to quality and performance that EDI products are known for, providing years of trouble free operation.

BIU-700 OPERATIONAL FEATURES

Basic Functions: The BIU-700 Bus Interface Unit meets or exceeds all requirements of the NEMA Standard TS2-2003 for the BIU configuration.

Display Indicators: Separate Power, Receive, and Transmit LED indicators display DC power status and SDLC Port 1 status.

Input / Output Pins: Signal I/O Configuration:

15 DC Output pins 24 Programmable Input / Output pins 8 DC Input pins 4 Optically isolated input pins 1 Line Frequency Reference input pin 4 Address Select input pins

Output Drivers: All outputs are rated at 150mA continuous sink current. Each output provides a 500mA typical current limit. Outputs are rated to 50 volts and utilize a voltage clamp for inductive transient protection.

Isolated Inputs: Four optically isolated inputs provide isolation for Pedestrian Detector and Remote Interconnect inputs. These inputs are intended for direct connection to 12 Vac from the cabinet power supply for Pedestrian Detector applications. They may also be connected for 'Low True' DC applications when the Opto Common pin is connected to a 24Vdc supply.
