2 Automation Components, Inc. CURRENT 4-20 MA OUTPUT 4-20 MA OUTPUT CTA2, SCTA2, CTA2-RMS & SCTA2-RMS Series The 4-20 ma Output Analog Current Sensors are designed for use in any AC current monitoring application in which you are looking to monitor a particular piece of equipment. The style current sensors should be used in applications where the Sinusoidal waveform has no distortion or noise on the conductor being monitored. Applications may include monitoring a resistive type load such as an incandescent light bulb, heating element as well as any single speed linear load. Note that the True RMS sensors are able to be used in all applications since the True RMS current sensors provide the best overall accuracy and should be used in applications which includes Variable Frequency Drives, Switching Power Supplies, Computers and Data Centers, Electronic Ballasts, SCR s, and Variable Speed Loads. For currents monitored above 250 Amps, the CTA2-5 and SCTA2-5 are ideal for use with a step down Ratio:5A Output CT (Current Transformer) in stepping down current in a monitored conductor to a proportional 0 to 5A output signal. The current sensors are available in both solid and split-core versions which also includes a Patented (Pat. No. US 7,416,421) 35 mm Din Rail mounting foot for easy installation in panel mount applications. The solid-core versions are a great choice for new installations or OEM applications in which cost sensitivity, lower trip points and environmental issues like dust and moisture may be of concern. The split-core version of the current sensors work great in retrofit applications and for use on service technicians vehicles since one or two parts will work in most applications and can be easily installed without disconnecting any wires. Applications: Load Trending, Basic Power Monitoring, Electronic Ballasts, Computers/Data Centers, Industrial, Variable Speed Loads, Pumps, Compressors, Fans, Preventative Maintenance, LEED, Project Justification (ROI) Process Control, Solid State Environments (SCR s) The 4-20 ma Output Current Sensors are covered by ACI's Five (5) Year Limited Warranty.

8 Automation Components, Inc. CURRENT VOLTAGE OUTPUT VOLTAGE OUTPUT CTE2, SCTE2, CTV2 & SCTV2 Series The Voltage Output Analog Current Sensors are designed for use in any AC current monitoring application in which you are looking to monitor a particular piece of equipment for proper operation. All voltage output current sensors use an current measuring method and should be used in applications where a pure Sinusoidal AC waveform that has very little or no distortion/noise on the conductor being monitored. Applications may include monitoring a resistive type load such as an incandescent light bulb or heating element as well as any single speed linear load. Voltage Output current sensors are available in both solid and split-core versions which also includes a Patented 35 mm Din Rail mounting foot for easy installation in panel mount applications. The solid-core versions are a great choice for new installations or OEM applications in which cost sensitivity, lower trip points and environmental issues like dust and moisture may be of concern. The split-core version of the current sensors work great in retrofit applications and for use on service technicians vehicles since one or two parts will work in most applications and can be easily installed without disconnecting any wires. For best results, the voltage output current sensors should not be used in applications with switching power supplies or variable speed drives due to the limited operating frequency range. In applications where variable speed drives or waveforms include distortion/noise, ACI recommends the use of the A/CTA2-RMS or A/SCTA2-RMS Series sensors where you need to supply 24 VDC power to the current sensors with a 4-20 ma signal. A 249 Ohm or 499 Ohm 1 Watt resistor can be used to convert the 4-20 ma signal into a useable 1-5 or 2-10 VDC output signal at your building management system or PLC. Applications: Load Trending, Single Speed Loads, Pumps, Compressors, Fans, Preventative Maintenance, LEED, Project Justification (Calculating ROI), Process Control The Voltage Output Current Sensors are covered by ACI's Five (5) Year Limited Warranty.

The split-core version of the current switches work great in retrofit applications and for use in service vehicles since one part will work in most applications and can be installed without disconnecting any wires. Fixed status switches can also be used to determine the run time of your equipment when logging the contact closures on your building management system or PLC. Applications: On/Off Status Indication, Local Alarms such as Strobes/Audible Alarms, Pumps, Fans, Compressors, Lighting Status and Usage Information, Ovens, Process Control, Industrial Equipment, OEM Opportunities The Miniature Fixed Current Status Switches are covered by ACI's Five (5) Year Limited Warranty. The warranty can be found in the front of ACI's Sensors & Transmitters catalog, as well as on ACI's website, PRODUCT SPECIFICATIONS Monitored Current Type: Maximum AC Voltage: Operating Frequency Range: Core Style: Sensor Power: Amperage Range: Isolation Voltage: Trip Point Style Adjustable Trip Point Range: Contact Type: Status Contact Rating: Status Contact On Resistance Off Resistance: Response Time: Status LED Indication 1: Aperture Size (Diameter): Operating Temperature Range: Operating Humidity Range: Recommended Storage Temperature RH Range: Enclosure Material Flammability Rating: Wiring Connections: Wire Size: Terminal Block Torque Rating: Minimum Mounting Distance: Agency Approvals 2: Product Weight: Product Dimensions (L x W x H): AC Current 600 VAC 50/60 Hz and Versions available (See Ordering Grid) Induced from the Monitored Conductor (Insulated Conductors only) See Ordering Grid 2200 VAC Fixed Trip Point See Ordering Grid Normally-Open N/O 0.5A 36 VAC/VDC < 0.5 Ohms (tripped) > 1 Meg Ohms (Open) A/MCS: < 50 ms typical A/MSCS: < 40 ms typical Red LED (Current above trip point) Blue LED (Current below trip point) 0.53 (13.46 mm) -22 to 140ºF (-30 to 60ºC) 0 to 95%, non-condensing 41 to 95 F (5 to 35 C) 40% to 85% RH, non-condensing PC/ABS (Polycarbonate/ABS Blend) UL94-V0 2 Position Screw Terminal Block (Not Polarity Sensitive) 16 to 22 AWG (1.31 mm2 to 0.33 mm2) Copper Wires only 4.43 to 5.31 in-lbs.
