1Introduction

The LDSBus HVT-Junction connects LDSBus

Devices (Sensors /Actuators) to the LDSBus. It

serves as a data and power interface between

the LDSBus host and the LDSBus devices. Each

LDSBus HVT-Junction can connect up to four

LDSBus Devices. Additional LDSBus HVT-

Junctions may be daisy chained to add more

LDSBus devices to the bus.

1.1 Features

•Connects LDSBus devices to LDSBus Host

and supports daisy chain connections through

the RJ45 LDSBus ports

•Supports four LDSBus device connections

through the RJ11/RJ12 LDSU ports

•Built-in DC-DC converter for stepping down

the LDSBus +24VDC supply to +5VDC for

LDSU ports

•Built-in Voltage protection for RJ45 ports

•Built-in Overcurrent protection

•Flush mount and DIN Rail mounting options

•Operating temperature range : 0oC to +70oC
