Chapter 1 Functional Description

1.1 Overview of the Recorder

The RD100B Recorder (hereafter referred to as the recorder) can be used to assign DC voltage, 1-5V, thermocouple, RTD, and contact or voltage ON/OFF signal to channels for measurement. The measured results are recorded with pens or dots on a chart paper that is fed at a constant speed. The pen model can record up to 4 channels; the dot model can record up to 6 channels.

Alarms

For each channel, various alarms such as high limit alarm and low limit alarm can be assigned to monitor the measured values. Alarm output relays can be used to output contact signals when alarms occur (/A1, /A2, and /A3 options).

Recording

The measured results are recorded with pens or dots on a chart paper (trend recording). The chart speed can be selected from 5 to 12000 mm/h on the pen model and 1 to 1500 mm/h on the dot model.

In addition to trend recording, various types of information can be printed or recorded on the chart paper such as numeric measured values, alarm occurrence/release, and predefined messages.

Also, the recorder settings can be printed.

Internal Light

A light is provided for easier viewing of the recording area of the chart paper.

Display

Measured values can be displayed numerically or using bar graphs on the large display.

Also, alarm status and chart speed can be displayed.

Communication Function

Using the Ethernet communication interface (/C7 option) or the RS-422A/485 communication interface (/C3 option), the measured values on the recorder can be output to a PC or a PC can be used to control the recorder.

This manual does not cover the communication functions. For details on communication functions, see the RD100B/RD1800B Communication Interface User’s Manual on the CD-ROM.

Other Main Functions

The computation function (/M1 option) can be used to perform various computations from four arithmetic operations to statistical calculations on 8 and 12 computation channels on the pen model and dot model, respectively. The computed results can be recorded.

The remote control function (/R1 option) can be used to control the start/stop and other operations of the recorder by applying contact signals to the dedicated terminals.

The FAIL/chart end detection and output function (/F1 option) can be used to output contact signals when errors are detected on the recorder or when the chart paper runs out.
