250mm Multipoint Strip Chart RecorderSR250BSS/SR250B_2SR250BThe SR250B provides accurate and reliable recording of upto 12 process signals on a 250mm wide chart. In-built textprinting capabilities give clear annotation on the chart oftime, date, scales and other process information.The clear view of process status from the LCD display, withthe simplicity of chart and pen replacement, make theSR250B extremely easy to operate.The recorder is designed for panel-mounting and providesIP65 (NEMA3) dust and water protection on the front face,making it suitable for use in harsh environments.The SR250B can be configured for a wide range of inputtypes and chart speeds and is ideal for most industrialrecording applications.Application areas include:■ Heat Treatment■ Ceramics Manufacture■ Cold Storage■ Power GenerationProcess ConnectionsUp to 12 Universal Inputs• Thermocouple• RTD• mA• millivolts• Volts• Up to 12 Traces• Chart Annotation• Alarm Messages• Time/Date• Trace Indentifiers45mA TransmitterPower Supply12 x Relay Outputs2 x 70mA TransmitterPower SupplyRS485 Modbus RTU1 x Digital InputStandardOptional2

250mm Multipoint Strip Chart RecorderSR250BSS/SR250B_2RecordingThe SR250B’s high-speed multi-point printing system updatesall 12 traces in 2.2 seconds. This system produces continuouslines on the chart at speeds of up to 500mm/hr.The printing sequence is intelligently managed by the recorder’scontrol system to give priority to fast-changing signals, ensuringthe most comprehensive process record is traced on the chart.The SR250B supports full text printing to provide detailedannotation on the chart. In addition to the time, date, channelidentity and chart speed, the recorder can print scales for eachchannel, alarm messages and an Operator-entered batch name.The 'Easy-view' facility enables the user to see the latestrecordings at the push of a button.OperationA graphic liquid crystal display (LCD) provides exceptional clarityfor day-to-day operation and for configuration.During normal operation the display cycles through eachchannel in sequence, showing the measured value, engineeringunits, description and channel identifier.Clear text prompts on the LCD display assist the Operator inaccessing functions such as chart reload and alarmacknowledge. Tactile membrane keys on the front of therecorder are used to access these functions. A second, identicalkeypad is provided inside the recorder for use when the door isopen.Unique Post-incident Analysis(Cue-and-Review)The SR250B’s unique 'Cue-and-Review' facility allows the userto rapidly search any part of the roll chart for process events oralarm occurrence – enabling rapid and accurate analysis ofprocess records.Password protection prevents unauthorized access to therecorder’s configuration.Quickly-fitted pen cartridges and an easily-removable chartcassette ensure simple and efficient pen and chart replacement.3

250mm Multipoint Strip Chart RecorderSR250BSS/SR250B_2Set-upThe SR250B can be easily set up to match your process in eitherof two ways:Entry of the correct password via the keypad on the front of theunit gives access to the recorder's configuration. A simple menustructure with clear text descriptions provides an intuitiveapproach to the recorder set-up.The preferred configuration method for multiple SR250Brecorders is by means of the PC Configurator. This Windowsbasedpackage provides a simple 'point-and-click' approach togenerating a full recorder configuration off-line. The completedconfiguration can be printed-out or saved onto disk before beingdownloaded to the recorder.An SR250B interface cable is used to provide the connectionbetween the PC’s serial port and the configuration port on therecorder.Option ModulesAll recorders are fitted with at least one universal input modulefor analog process signals plus a transmitter power supply for upto two 2-wire transmitters.The capabilities of your recorder can be extended by theaddition of further option modules. Each recorder can supportup to 2 input modules plus 3 option modules.I/O OptionsTypeStandardUniversalInputs3, 6, 9 or 12OptionRelays0 12TransmitterPower Supply (loops)2 12SerialCommunicationsX ✓4

250mm Multipoint Strip Chart RecorderSR250BSS/SR250B_2Application Function Overview09:00 PaA PaANOThe recorder prints time, date and chart speed automatically at regular intervals.Channel scales and batch identifiers can also be printed on the chart periodically oron demand.Up to 24 process alarms can be set up within the recorder. Alarm status can beprinted on the chart and the alarms can operate relay outputs or change the chartspeed.5V0VNCA maximum of 12 relays can be fitted within the recorder for use as alarm outputs. Asingle common relay can be set to be triggered by multiple alarms.A digital input is provided on every Input Module for remote changing of chart speedor for alarm acknowledgment.RS485 2- or 4-wire communications using Modbus protocol provides a real-time linkto SCADA systems or PLCs.Temperature RecordingRecording of temperature, using both direct-connectedthermocouples and RTDs or 2-wire field-mountedtransmitters, is common in a wide range of industries suchas Aerospace, Car component, Food, Chemical and Kiln/Ovens.The SR250B can accept direct connection to all standardthermocouples, Pt100 resistance thermometers and 4 to20mA transmitters, and record on up to 6 channels ordatalog up to 12 inputs.Operator messages allow printing of configurable messages such as'Start of Test' or 'Cycle Complete' for a clear record of the batch.For electric ovens fit the 500V isolator card to avoid conductance on thethermocouple which causes noise on the chart.SR250BTemperature Monitoring and AlarmsIn food production, it is essential to monitor theconditions in Cold Stores and TemperaturecontrolledRooms to provide the user with a recordthat the goods have been stored at the correcttemperature.The simplest and easiest way to do this is with theSR250B strip chart recorder, which can take up to6 inputs from RTDs spread across a cold store or anumber of food preparation areas.At a chart speed of 20mm/hour, the unit providesrecording for one month and, when fitted with relayoutput modules, provides alarm functions.TemperatureSensorConnectionsLoading andUnloading BayFrozen Food Store(not drawn to scaleas stores may be verylarge – e.g. 10,000m 2and larger)Temperature Sensors(individual cable runs tothe SR250B Recorderensure accuracy andprofile of store )Racking andStorage PalletsControl CabinSR250B5
