1.1 Overview of the Recorder
The SBR-EW180 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 24 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, /A3, /
A4, and /A5 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 SBR-
EW100/EW180 Communication Interface User’s Manual (IMSBR08-E( )).
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 24 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.
