A-B 1746-NR8 SLC 500™ RTD/Resistance Input Module

Overview

This chapter describes the 8-channel 1746-NR8 RTD/Resistance Input

Module and explains how the SLC controller gathers RTD (Resistance

Temperature Detector) temperature or resistance-initiated analog input from

the module. Included is:

· a general description of the module’s hardware and software features

· an overview of system operation

For the rest of the manual, the 1746-NR8 RTD/Resistance Input Module is

referred to as simply the RTD module.

The RTD module receives and stores digitally converted analog data from

RTDs or other resistance inputs such as potentiometers into its image table for

retrieval by all fixed and modular SLC 500 processors. An RTD consists of a

temperature-sensing element connected by 2. 3. or 4 wires that provide input

to the RTD module. The module supports connections from any combination

of up to eight RTDs of various types (for example: platinum, nickel, copper, or

nickel-iron) or other resistance inputs.

Description

The RTD module supplies a small current to each RTD connected to the

module inputs (up to 8 input channels). The module provides on-board

scaling and converts RTD input to temperature (°C, °F) or reports resistance

input in ohms.

Each input channel is individually configurable for a specific input device.

Broken sensor detection (open- or short-circuit) is provided for each input

channel. In addition, the module provides indication if the input signal is

out-of-range. For more detail on module functionality, refer to the subsection

entitled System Overview later in this chapter.

ABB industrial drives ACS6080 5 to 36MW

ACS6080 medium voltage drives offer high dynamic performance,

reliability and safety for demanding applications.

On top of ABB’s new MP³C control technology, the drive provides easy-to-use interfaces to

simplify operation and ABB Ability™ remote condition monitoring.

Increased productivity due to new MP³C control technology

The ACS6080 drive includes ABB’s breakthrough control capability, known

as Model Predictive Pulse Pattern Control (MP³C). The new advanced MP³C

technology offers the highest level of dynamic performance provided by

ABB’s direct torque control (DTC) together with the robustness and power

quality of predictive control. At every point in time this control can anticipate

the best motor operation point by finding the perfect compromise between

dynamics, efficiency and harmonic distortion.

The advanced control enables system integrators and plant operators to

maintain stability, while reducing investment and operational costs by using

a smaller drive or a smaller motor in most cases. The increased power

capability of the ACS6080’s single power module reduces the footprint of

the drive by up to 20 percent. The new control helps to reduce operational

cost in two ways: it is more energy efficient than other control solutions,

and maintenance costs are reduced as there is less mechanical and thermal

stress on the equipment leading to longer lifetime of the components.
