Transmitter/Receiver wirelessly monitors process conditions.NK Technologies Campbell, CA 95008
Apr 10, 2013 Completely transparent to existing equipment, WRT Series Wireless Data Transmitter/Receiver provides self-managed mesh network that works with any RS485 network protocol. System allows for wired and wireless equipment mixes to avoid radio signal obstacles, and offers wireless data transmission up to 100 m between receivers. Data transmission at up to 800 m is possible with multiple hops. Offering automatic route detection, WRT Series supports 100 nodes/network through 15 channels.
Current Transducers monitor distorted AC current.NK Technologies Campbell, CA 95008
Feb 07, 2013 Combining transformer and true RMS signal conditioner in single package, ATPR E-Out Series produces 0–5 or 0–10 Vdc RMS output on distorted waveforms located in output of variable frequency drives, phase angle fired heating controls, and on linear loads in noisy power environments. Output is proportional to current flowing in circuit even with high distortion or harmonic loads. Field selectable ranges accommodate changes in load conditions, while split core housing facilitates installation.
DC Current Sensors come in compact, non-adjustable package.NK Technologies Campbell, CA 95008
Jan 08, 2013 With one-piece design that facilitates installation, DS1 DC current sensors can be powered by 10–28 Vdc and use same circuit as one being controlled. Separate source may also be used as long as circuit being controlled uses same ground. Featuring solid state contact, sensors can also be used as non-intrusive safety interlock method to keep personnel safe, as alarm contact to indicate when load is operating or when it is not energized, and to detect PV system leakage.
AC Current Operated Switches simplify monitoring.NK Technologies Campbell, CA 95008
Dec 06, 2012 Available in panel-mount, solid- or split-core enclosure, ASL Series offers user-selectable linear setpoint adjustment for monitoring current in various applications. Contact actuation point can be set with no load present, and 2 sec delay ignores motor inrush current upon energization. While magnetically isolated output maximizes safety and eliminates insertion losses, solid-state design eliminates periodic maintenance and calibration. No external power source is required for operation.
ADC Signal Converters convert sensor output to Modbus format.NK Technologies Campbell, CA 95008
Nov 15, 2012 Accepting analog signals from up to 8 loop or separately powered sensors, ADC Series seamlessly converts signals to digital output that interfaces with Modbus RTU digital protocol using single network address. Sensor loop power supplied by converters can eliminate need for separate DC power supply. Featuring finger-safe field wiring terminals and DIN rail mounting, converters are suited for PV power production, machine control applications, and SCADA systems.
Current Sensing Switches offer adjustable setpoint from 1-80 A.NK Technologies Campbell, CA 95008
Sep 06, 2012 For use with 24 Vac/Vdc or 120 Vac supplies, ASXP Series features operation range of 40-100 Hz for monitoring single and 3-phase motors. Units come with solid-core enclosure and LED indicators for trip point contact status. Fixed 2-second delay trip timer eliminates nuisance alarms due to start-up inrush or temporary over-current conditions in motor or heater applications. In motor protection applications, sensors provide electronic proof-of-operation and detect current draw changes in motor.
Current Transducer/Switch monitors AC current up to 1,200 A.NK Technologies Campbell, CA 95008
Jul 10, 2012 Combining limit alarm with analog output signal transducer, ATS Series monitors produced or consumed AC current up to 1,200 A, while magnetically isolating outputs and inputs to maximize safety. Rotary switch enables user to set trip point, while DIN rail mounting facilitates installation and provides secure mount that is resistant to conductor movement. With single self-contained current switch, users can monitor air handling blowers, pumps, crushers, and other large loads.
Current Sensing Switch helps keep motors performing optimally.NK Technologies Campbell, CA 95008
Jun 21, 2012 Compatible with any automation system, ASM Series Smart-Switch uses actual load current to set trip point. Self-calibrating and self-powered switches accelerate start-up and come in 3 models to provide status monitoring, overload or underload, or operating window (overload and underload) functionality. Selection accommodates needs of particular pump, fan, heating element, conveyor, or multi-load safety-interlocked application. Output contact is AC and DC compatible.
Signal Converters change CT signal to standard 4-20 mA output.NK Technologies Campbell, CA 95008
Feb 23, 2012 Featuring snap-in installation, CTC Series lets users utilize existing standard 5 A secondary CT or low voltage (0.333 Vac) ProteCT(TM) current transformer with non-contact ranges as low as 0-5 A over conductor to produce standard 4-20 mA, 2-wire, loop-powered signal. DIN rail mounting and 24 Vdc loop-powered supply are standard, and no calibration is required; primary current transformer ratio provides scaling required without any installer intervention.
Large Aperture Transducers facilitate dc current monitoring.NK Technologies Campbell, CA 95008
Jan 13, 2012 DT Series combines hall effect sensor and signal conditioner into one package for use in DC current applications up to 1,200 A. Available in factory calibrated ranges that facilitate operation while also eliminating zero and span pots, large aperture current transducers offer 4-20 mA, 0-5 Vdc, or 0-10 Vdc outputs that are magnetically isolated from input for maximum safety. While internal power regulation delivers reliable operation, DIN-rail mount enclosure facilitates installation.
