2 SENTRO trip amps incorporate advanced design technology to combine simple installation with rapid, cost-efficient maintenance and the highest safety performance......built to withstand adversity HIGH STRENGTH MOULDED HOUSING Dual wall construction for maximum impact strength. Sealed against dust and moisture to IP65 standard. EMC protected. LARGE LCD READOUT High-brightness, dot matrix display provides clear information with direct on-screen instructions and diagnostic data. PRE-CALIBRATED INPUT MODULES Intelligent and standardised sensing modules for a choice of input signals can be interchanged in seconds. Data storage of all sensing parameters and service history. No danger of inserting a wrong module; up to 30 insert codes can be user configured and SENTRO will automatically identify the module. Data logging. SECURE, EASY CONNECTION Large terminals with open visual access can easily clamp two 4mm 2 conductors. Spring loaded wire clamping plate ensures safe and vibration secure connections. RAPID & ROBUST MOUNTING All SENTRO series housings are designed to easily fit onto standard Unistrut rails. SIMPLE CABLE TERMINATION Large spacious terminal chamber with adequate space for terminating heavy plant cables. Two M20 threaded cable entries for simple fitting of cable glands. Hinged segregation cover for added operator safety. 2 /7

3 sentro modules... There is a wide choice of sensing modules available and each one stores all the necessary data about its type identification, sensing range and specific calibration. This data is automatically recognised by SENTRO when the rmodule is plugged in points of date-stamped measurements are also logged and can be reviewed by connecting the module to a USB port on a standard PC, or the logged data may be retrieved from the Trip Amp via an RS485 datalink to a PC. The service history of the module is also recorded. The rmodules are pre-calibrated so can be substituted any time by a replacement module usually of the same type, but an alternative may be inserted if required. Security coding can be used to ensure that the same type of SENTRO rmodule is always used....'smart' gas modules SENTRO rmodule REMOTE CONNECTED SENSORS SENTRO rmodule for remote connection of a variety of field mounted sensing devices. rmodules incorporate screw terminals to accept direct input connections of cables from remote analogue or digital sensors. TX mA Industrial standard analogue sensor input 2 and 3 wire connections. 4 2V 20mA TX V Voltage input signals, analogue sensor input 2 and 3 wire connections V TX PT100 Standard PT100 temperature monitoring input with line compensation. TX ac Low level ac input signals from vibration sensors and ac devices. TX mv Low level dc mv signals for strain gauges and load cells. TX DIGITAL Pulse and frequency input signals from speed monitoring sensors and frequency generating devices. INPUT MODULE SETTINGS Input modules are normally supplied with preset function data and no further setting-up will be necessary SENTRO will immediately recognise the module and its settings when it is loaded. Module parameters can also be setup to individual requirements when requested. Scaling, duty text and setpoint alarm values are pre-programmed. 3 /7

4 convenient calibration adjustment... SENTRO input modules are normally supplied fully calibrated to specific requirements and no further adjustment is needed. ZERO and SCALE values can be changed to individual requirements after installation where it may be necessary to compensate or adjust for prevailing site conditions. An input signal may have shifted or an 'offset' may be required SENTRO can be empirically calibrated in a choice of two simple ways: REPLACE THE MODULE choice of calibration methods False alarms will be automatically inhibited during change-out. The SENTRO cover stays anchored in place, ready for 'quick' replacement. IR COMMANDER Calibrate using the two button remote IR Commander no need to remove the cover. Follow the simple, step-by-step, on-screen instructions. The same thing can be done using the internal calibration buttons if required. 4 /7

5 efficient maintenance... Whatever service needs to be carried out, it is simple and quick engendering confidence in the product so ensuring a greater level of plant safety....highly costeffective Recalibrate by changing the gas sensing module. Rapid calibration using the IR Commander. The complete main internal control module can be changed if major service is required. Clear and concise diagnostic messages and function data.

6 choice of input signal, power supply and outputs... One of the most important characteristics of a monitoring system is its ability to integrate directly in a trouble-free way, with other plant equipment and monitoring devices. SENTRO has no equal in its choice of input/output signals and direct power-up options to satisfy most plant preferences just forget about additional power-packs or signal interface devices; they won't be needed mA V INPUT SIGNALS PT100 ac/vibration Dual contacts RS485 data OUTPUT SIGNALS mv sentro integrates directly Digital system flexibility V ac 110V ac 24V dc POWER IN STANDARD POWER SOURCE Uses standard locally available power sources; 24V dc or 110V ac or 230V ac. OUTPUT CONTACTS or RS485 DATA Dual contacts with audio/visual alarm warnings incorporated, so doing away with remote auxiliary alarm devices. Cable saving SENTRO option with RS485 datacomms. Alarm status data can be transmitted by 32 SENTRO Trip amp/ Monitors on a single RS485 data cable, communicating with a central PC. RS485 DATACOMMS 6 /7
