TRICONEX 3806E modular

Description

3806EAn external termination panel (ETP) is an electrically-passive printed circuit board (PCB) towhich field wiring is easily attached. A panel connector, terminal blocks, and optionalcomponents are mounted to the PCB and enclosed in a DIN-rail compatible plastic housing. Atermination panel and associated cable pass input signals from the field directly to an inputmodule, or pass output signals from an output module directly to field wiring. 3806EThisarrangement permits the removal or replacement of I/O modules without disturbing fieldwiring.Standard termination panels are best for remote marshaling of field wiring where maximumflexibility, high density and simple maintenance is desired. Standard termination panels allowyou to marshal field signals in a separate enclosure up to 99 feet (30 meters) from a Tricon.A standard termination panel consists of a PCB with all necessary 3806Ecomponents—such as two-piece terminal blocks, resistors, fuses and blown-fuse indicators—mounted on a DIN-railcompatible plastic housing. The housing snaps into mounting rails in accordance withDIN 50 22.Compression terminals on the standard panel are designed for use with 24- to 12-gauge (0.3mm2to 2.1 mmhave a fuse with a blown-fuse indicator, to protect the field wiring and field device.Standard termination panels are pre-configured for a specific application. For instance,commoned standard termination panels can be ordered with commoned power-and-return, orredundant DC power configurations with a diode-ORing. The thermocouple input terminationpanel provides 3806Ecold-junction temperature sensors and can be ordered with upscale, downscale,or programmable burnout detection. A standard termination panel for analog voltage inputsprovides commoned or non-commoned signal returns, while the current-mode version has aprecision resistor at each input point to convert current to voltage.Each standard3806E termination panel is packaged with a matched interface cable that connects 3806Ethepanel to the backplane of a Tricon chassis. A female connector at one end of the cable is keyedto match the male connector on the Tricon backplane. A male connector on the other end of thecable attaches to the standard termination panel.In addition to standard termination panels, there are other types of termination panels,including:• Basic termination panels• Hazardous location (nonincendive) termination panels• RG 1.180 Termination Panels• Termination panels with interposing relays• Bypass panels for digital inputs• Termination panels with RTD/TC/AI input signal conditioning• Termination panels for 3603B digital output modules• Termination panels for 3806E analog output modules
