Model HI 215IT 215JB - IT Junction Box And C2 Cable Brochure

C2® CABLEHardy C2® Certified Cable has been designed specifically for the electrically and mechanically harsh environments found in Process Weighing applications. While many process variables are transmitted at a 0-10 volt or 4-20 milliamp level, signals from load or force sensors are typically one thousand times smaller, or 0-0.010 volts. A ten pound change on a 100,000 pound scale would correspond to a signal change of 0.000001 volts (1 micro volt). Therefore, cabling must protect against electrical noise common in the plant environment.It is also imperative that moisture not enter the cable as it would increase capacitance and allow coupling of voltage from the excitation wires to the signal wires. The coupling of voltage causes “drifting” weight indications. Use of improper cable between even the finest load sensors andinstrumentation will yield poor weighing results. The costs and time delays of removing and replacing improper weighing system cable are prohibitive. To insure an effective weighing system, always specify Hardy C2 Certified Cable.ApplicationsPROCESS WEIGHING• Batching/Blending• Filling/Dispensing• Level-by-Weight• Check WeighingFeaturesC2® Electronic Calibration• Electronic calibration without test weightsINTEGRATED TECHNICIAN® (IT)• Weighing system monitoring and troubleshootingJUNCTION BOXThe Hardy C2® certified Junction Box contains circuitry in a waterproof enclosure which distributes the excitation voltage to up to four load points and transfers each load point’s performance characteristics and weight signals to the weight controller. The junction box, without being opened, allows an instrument operator to switch in an internal test circuit to test the stability of the cable from the junction box to the INTEGRATED TECHNICIAN® (IT) equipped weighing instrument. In addition, individual load sensors can be isolated for weight and voltage readings all from the weighing instrument’s front panel.The box’s unique removable multiple connector design allows for easy isolation and trouble-shooting of non-IT® capable weighing systems. Two junction boxes can be cabled together to handle up to eight load points from a single scale. Available in NEMA 4 rated painted steel, NEMA 4X rated stainless steel or fiberglass, each box comes with two packaged hole plugs and five cable grip fittings suitable for O.D. cable of 1/4 to 3/8 inches. A label isprovided on the underside of the top cover to record load point positions. A non-C2 version with trim pots is also available. www.hardysolutions.com • 800-821-5831IT Junction Box and C2 CableModel HI 215IT / 215JB C2 CABLETo learn more about the HI 215JB visit our web site for:• full product specifications• ordering information• application notes• technical description• operator’s manualwww.hardysolutions.comor call us: 800-821-5831+1-858-278-2900www.hardysolutions.com • 800.821.5831JUNCTION BOXHardy Process Solutions9440 Carroll Park Dr.San Diego, CA 92121tel. +1-858-278-2900tel. 800-821-5831fax +1-858-278-6700www.hardysolutions.comhardyinfo@hardysolutions.comSince 1993HI 215IT-JB0611 0400-0007AAll information within is subject to change without notice.

Unlike other process measurements, incremental changes in weight correspond to signal changes typically in the range of 0.0000001 volts (0.1 micro volt). Without proper shielding, common plant electrical noise can cause fluctuation and incorrect weight readings.The thick (0.060") outer jacket protects signal leads from minor nicks and cuts, and helps keep moisture and contaminants out. The vinyl material used is flexible for conduit bends and slides more easily in long conduit runs. Additionally, this material resists many corrosive substances.A mylar barrier reduces the chance of moisture reaching the signal lea ds should the cable be nicked. Moisture between signal leads increases the capacitance between signals and results in cross coupling of voltages and incorrect weight readings.The 22 gauge wire is stranded for reliability in bends and is color coded for easy installation.Two wires make up a twisted pair to reduce capacitance for C2 signals and provide a constant cable impedance.A B CDEApprovals• CE• FM, Class l, ll & lll, Div 1 & 2 Groups A, B, C, D, E, F & GWarranty• Two-year warranty against defects in workmanshipHardy Bench Scales, Floor Scales and Load PointsHardy carries a wide variety of strain gauge load points and scale bases to accommodate your application requirements.Weighing Instruments Dedicated to Your ApplicationsControllers, Weigh Modules, TransmittersAllen-Bradley® Compatible Plug-in Weigh Scale ModulesHI 3000 Series and HI 4050 ControllersADVANTAGE Series Load Point with C2 CalibrationANY-WEIGHScalesCOMPONENTS TO COMPLETE YOUR HARDY SYSTEM MAKESTOCKPACKSHIP
