TRICONEX 2658 Termination Panel

Understand what we do

The industrial automation and control industry serves as the "nerve center" and "brain" of manufacturing and infrastructure. It utilizes computer systems, software, networks, robotics, along with various sensors, controllers, and actuators to achieve automated control, monitoring, and optimization of industrial machinery, production processes, and plant facilities.

Its core objectives are to enhance production efficiency, ensure product quality, safeguard personnel and equipment safety, and reduce energy consumption and operational costs, all while minimizing human intervention.

From traditional mechanical manufacturing, chemical and metallurgical industries, to modern automotive production lines, food packaging, semiconductor manufacturing, and further extending to smart buildings, water treatment plants, and power stations—the application of industrial control technology spans nearly all fields of modern industry.

Overview

The Triconex 2658 (specifically 2658-1) is a Termination Panel designed to interface with the Triconex 3636R Relay Output Module. It facilitates non-commoned relay outputs for Tricon v9–v11 safety systems.

External Termination Panels

An external termination panel (ETP) is an electrically-passive printed circuit board (PCB) to which field wiring is easily attached. A panel connector, terminal blocks, and optional components are mounted to the PCB and enclosed in a DIN-rail compatible plastic housing. A termination panel and associated cable pass input signals from the field directly to an input module, or pass output signals from an output module directly to field wiring. This arrangement permits the removal or replacement of I/O modules without disturbing field wiring.

Standard termination panels are best for remote marshaling of field wiring where maximum flexibility, high density and simple maintenance is desired. Standard termination panels allow you 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 components—such as twopiece terminal blocks, resistors, fuses and blown-fuse indicators—mounted on a DIN-rail compatible plastic housing. The housing snaps into mounting rails in accordance with DIN 50 22.

Compression terminals on the standard panel are designed for use with 24- to 12-gauge (0.3 mm2 to 2.1 mm2) wiring. Some panels have an optional current-limiting series resistor, others have 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, or redundant DC power configurations with a diode-ORing. The thermocouple input termination panel provides cold-junction temperature sensors and can be ordered with upscale, downscale, or programmable burnout detection. A standard termination panel for analog voltage inputs provides commoned or non-commoned signal returns, while the current-mode version has a precision resistor at each input point to convert current to voltage.

Each standard termination panel is packaged with a matched interface cable that connects the panel to the backplane of a Tricon chassis. A female connector at one end of the cable is keyed to match the male connector on the Tricon backplane. A male connector on the other end of the cable attaches to the standard termination panel.

In addition to standard termination panels, there are other types of termination panels, including:

l Basic termination panels

l Hazardous location (nonincendive) termination panels

l RG 1.180 Termination Panels

l Termination panels with interposing relays

l Bypass panels for digital inputs

l Termination panels with RTD/TC/AI input signal conditioning

l Termination panels for 3603B digital output modules

l Termination panels for 3806E analog output modules
