YOKOGAWA DA100-23-1W Product Description

Overview

YOKOGAWA DA100-23-1W is a Yokogawa DA100 Darwin data acquisition unit for industrial measurement, logging and monitoring. The Yokogawa DA100 series is a discontinued distributed data acquisition system used to collect temperature, voltage, current, thermocouple, RTD, strain, pulse, power, contact and other process signals through plug-in input modules, then transfer measured data to a PC over a general-purpose communication interface. The DA100-23-1W is configured as an expandable DA100-2 main unit with AC supply and the suffix wiring or power-cable variant W. It serves as a replacement DA100 spare in existing Yokogawa Darwin measurement installations.

Features

According to the DA100 suffix code, the model DA100-2 is the expandable main unit. The suffix 3 corresponds to DAQ32 software attached with the unit. The supply suffix 1 indicates 100 to 240 V AC power. The final W indicates a 3-pin inlet with screw conversion terminal per the DA100 subunit and power-supply inlet code table; distributor listings describe the unit as 100 to 240 V AC, 50/60 Hz, S10 or Darwin-style configuration.

The expandable DA100-2 main unit itself has no local input channels; input modules are installed on DA100 subunits such as DS400 or DS600. Up to 6 subunits can be connected to a DA100-2, expanding the system to a maximum of 300 channels. The DA100-2 main unit can accept communications modules, alarm contact output modules and DI/DO modules, with a maximum of four modules connected; one module must always be a communications module.

Supported input module types include universal input for DC voltage, thermocouple, RTD and contact; DC voltage, thermocouple and digital input dedicated modules; power monitor; strain; pulse; and direct current mA modules. Communications modules include GP-IB, RS-232C, RS-422A/485 and Ethernet. Measurement data is logged or transferred using DAQ32 standard software or optional DAQ32 Plus functions, depending on the installed software and configuration.

Principle

The DA100-2 main unit coordinates measurement, module configuration, alarm handling and communication for connected DA100 subunits and input modules. Field sensors or process signals are wired to the appropriate input module on a DS400 or DS600 subunit. The input module conditions and digitizes the sensor signal, such as thermocouple or RTD temperature, DC voltage, mA current, strain bridge, pulse frequency or power measurement, and transfers the data to the main unit through the DA100 expansion connection.

The main unit communicates with a PC through the installed GP-IB, RS-232C, RS-422A/485 or Ethernet module. DAQ32 or DAQ32 Plus software sets measurement conditions, starts or stops measurement, displays data, records logs, performs diagnosis and calibration, and supports computation or report functions where the option is fitted. Alarm contact output modules and DI/DO modules provide external alarm or control interface signals where required.

Replacement should verify the exact main unit type, installed communications module, connected subunits, input module types and channel counts, software or option suffixes, expansion cable, power inlet and wiring, memory or configuration backup, and PC communication settings. Because DA100 systems are discontinued, the replacement unit should be checked for compatibility with the existing subunit modules, communication module and legacy software before commissioning.

Applications

YOKOGAWA DA100-23-1W is used in legacy Yokogawa Darwin data acquisition and monitoring systems for test benches, laboratory measurement, production monitoring, plant data logging, thermal process recording, machine and equipment condition monitoring, strain or load measurement, power measurement, pulse counting, temperature distribution surveys, process variable recording and research or development testing. Typical installations include industrial machinery, HVAC and environmental tests, automotive and component test equipment, electronic and electrical testing, utilities, process plants and material handling monitoring. In existing DA100 systems, the unit serves as a direct replacement expandable main spare matched to the original subunits, input modules, communication interface and software configuration.
