0 Replies and 24 Views CR8300 Series  24  0 Started by  Lee Kia Ching Dear Sir/Madam, May I know if CR8350 is able to meet the requirement of <0.5 total accuracy over the temperature range of -40 to 85 °C, taken into consideration of linearity error as well Let say I am using burden of 3.4 Ohm with 100A max input current. Thank you. Regards Lee Kia

0 Replies and 300 Views CR-45 and/or CR-2550  300  0 Started by  Fred Kersten I use heating cables to keep my home gutters from freezing. I have 3) cables; each connected to separate 15amp 110/120 VAC circuit breakers with separate illuminated switches. This lets me know when the power to each cable is turned on or not but doesn't let me know if the cable has failed or not. Two of the cables draw 0.83 - 0.75 Amps each at 120VAC. The third draws 3.35 Amps at 120VAC. Measurements were taken with a home grade Radio Shack digital multi-meter using a custom wiring plug in harn...

0 Replies and 538 Views CR5211S-50  538  0 Started by  Kip Guerrero Hi, I've had five current transducer stop sending output voltage shortly after installing them in our system. I suspect somehow our system is 'burning' them out. On initial install we would see the output voltage we would expect but after one or two checks the output voltage would go to -2.9VDC and stay there even if current was present. We are using the current transducer for measuring Welder current a max of 35AMPs DC. We suspected that there might be in-rush or a spike from the we...

0 Replies and 343 Views CRD5110 Modbus  343  0 Started by  Steve Fry I'm writing a program in LabView to communicate with CRD5110-150-25M serial transducer. I can set up New Serial Master for RTU, Unit ID 1, baud rate 9600, parity none, flow control none. I try to read input register location x10 but the read times out and does not return anything. I have increased the timeout to 3 seconds and it still does not work. Anyone use LabView with this transducer Or any other language with Modbus Thanks

1 Replies and 693 Views DC current transducer output  693  1 Started by  Lorne Lambert I have a CR9321-NPN that I thought it might be activated by DC current with the information on the label. I am hoping I could be guide to a DC current switch with the same out put as the CR9321-NPN as it is connected to a 1 wire device supplied by Welserver.com. The 24 VDC solenoid is 5000 ohms so the current is minimal. Thank you Lorne

5 Replies and 5633 Views cr9350-aca  5633  5 Started by  jim dayringer I'm using a cr9350-aca to energize a small interposing relay with a 120V coil and power draw of 9ma. Will I need a snubber circuit I found an old cut sheet for the cr9321-aca that showed a 2k ohm resistor and a .1uf capacitor as a recommended snubber. When I tried this it made the relay coil hum. The operation in either case was the same. Do I need the snubber to protect the current switch Thanks

2 Replies and 1280 Views DC Current Transducer transient protection  1280  2 Started by  Joel Huang I am looking at the CR5200 Series datasheet and I cannot find any information on the voltage transient tolerated in the input current line. We currently use the 936 Series from AAC which specifies 500V/uS voltage tolerance. Is there a spec for the CR5200 Thank you.

1 Replies and 2438 Views CR8350-2000-F step response  2438  1 Started by  David Gustavson I am considering using a CR8350-2000-F in a switching power supply. The spec sheet says frequency response to 200KHz. I need to know how the current transformer would respond to a 0 to 100 amp step in current. What would be the delay and rise time of the output signal Ideally a graph similar to what is on opamp datasheets would be great. Thanks, Dave Gustavson

1 Replies and 1913 Views CR9580 Questions  1913  1 Started by  Matt Mendenhall Question 1: I designed your CR9580-10-M into my system without realizing the product has such a long lead time for delivery, and I am still waiting on my first unit delivery to test and validate almost one month after I ordered it. The non-mounting case version CR9580-10 has a much shorter lead time. Does this part have just a smooth bottom, DIN rail, or How do people mount these Question 2: I plan to use the CR9580 with the output connected via an addressable switch that is connecte...

The requirements call for monitoring of AC and DC Voltage and Current of various equipment at 99.5 accuracy. I understand that Instantaneous voltage and current sensors would be required. If someone can guide me to the right product page, i can select one that meets site requirements. Thanks.

0 Replies and 2028 Views CR4395 For Open Heater Application  2028  0 Started by  Jim McKelvey I am interested in using the CR4395 for determining failure of a heating element in a railroad signaling environment. I have read through the relevant application document and still have a question about the operation of the output function (I am currently basing my design on use of a relay output). In my design, a PLC (installed in an instrument house in the field) receives a call for heat from a central office and in response energizes an output which turns on a heater control case (located...
