Description

TRICONEX 9753-1
An 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 TRICONEX 9753-1signals from an output module directly to field wiring. Thisarrangement 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 TRICONEX 9753-1density 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 TRICONEX 9753-1consists of a PCB with all necessary components—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 cold-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 standard termination panel is packaged with a matched interface cable that connects thepanel 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
