FIELDPAC™ 348 Field-Mounted Controller

Introduction

Features & Benefits

The need for only one wire pair to communicate with the control room reduces wiring costs

Combines multiple loop components in a single package for reduced hardware and maintenance costs

Improves loop accuracy by using digital technology and by eliminating data communication errors among multiple components.

The ability to communicate with the controller from a remote, central location improves operations

Implementation of the HART ® communication protocol facilitates use with many control system devices

Factory Configured Options (FCOs) reduce configuration time for standard control strategies

Flexible input options accommodate existing I/O

Description

The FIELDPAC 348 Field-Mounted Controller supports an advanced single-loop control applications, while reducing installed costs. The FIELDPAC controller lowers hardware costs by providing multiple loop components in one package and decreases wiring costs by reducing to one the number of wire pairs needed to transmit data to a central control room.

The loop components integrated within the FIELDPAC controller are based on the proven technology of several other instruments, including the Siemens Controllers, pressure transmitters, and

I/P and P/I converters. This combination allows the FIELDPAC controller to provide an innovative, reliable controller that can be mounted directly at the process site.

The FIELDPAC controller includes a TYPE 4X (IP65) enclosure and a hazardous area design (intrinsically safe and nonincendive) to allow installation at the process site. It offers several choices of direct process inputs, optional pneumatic or thermocouple/RTD inputs, and an optional pneumatic output, all of which are in addition to the standard complement of 4-20 mA inputs and discrete I/O.

The FIELDPAC controller also minimizes wiring costs via the HART protocol. With HART digital signal, the FIELDPAC controller transmits process data to a control room over one standard wire pair, instead of the three to four wire pairs required by a typical loop. Using HART also allows the FIELDPAC controller to communicate with many other devices, because HART has the largest base of any field communications protocol.

The FIELDPAC controller accommodates control strategies ranging from basic PID control to sophisticated loops, such as ratio, bias, single-station cascade, dual-loop and feed-forward control. Circuits are configured via the same function block technique employed with the Model 353 Process Automation

Controller, where the user simply selects the desired blocks, connects them, and sets parameters, such as gains and timer values. Moreover, the FIELDPAC controller provides over

60 pre-configured function blocks containing more than

200 functions.

In addition, the FIELDPAC controller provides many preconfigured control strategies (FCOs). Each FCO can be used as is, or customized as needed, significantly reducing configuration time for standard control requirements.

The FIELDPAC controller is configured locally or at a remote

PC. The station’s pushbuttons allow the FIELDPAC controller to be configured at the faceplate.
