We recommend 200mA of current can be taken from Pin 1 with the 5V supply. A: Pin 2 will sink 20mA of current.
Regarding your single dry contact RJ-45 sensor, can you please confirm the pin-out information for a dry contact that connects to one of the dry contact ports, also which pin supplies power (pin1, 5v,)?
Here is the pin-out for the dry contact sensor. The RJ-45 the combination is: White/orange, orange, white/green, blue, white/blue, green, white/brown, brown. On the sensor on the black wire: white/green … Read More
Is it possible to connect my securitySensor up in series, if I wanted to monitor a number of doors in the same building for example? If so, how do I do that?
Yes, the securitySensor can actually be wired in sequence. You can take the contact from one security sensor and wire it to the next. The only limit to the number … Read More
What is the accuracy of a 4-20mA converter?
The accuracy of our 4-20mA converters is 2%. The resolution of our 4-20mA converters is 0.1mA. You can use these figures in conjunction with your sensor?s accuracy to find the … Read More
I am sure that all settings for the Digital Voltmeter sensor are correct, but it seems to have error in the reading. How can I correct this error?
The Digital Voltmeter and 4-20mA sensors have an input as analog signal which will be converted to digital using an A/D converter. Normally, the A/D converter is calibrated in production … Read More
I just finished a calibration process, but the reading is still a little bit off. Is there any way to fine tune the reading?
In the calibration process, we set the offset of the reference voltage so that the raw analog read 500 when the input to the RJ45 port is 1.25 volts. However, … Read More
Do you have any sensor that is capable of reading the fluctuation of electricity, and send me reports?
How to monitor electricity fluctuations? We have a sensor that is capable of monitoring Voltage, Wattage and Amperage. This is our Power Meter Sensor. You can set alerts as with … Read More
I noticed you have an airflow sensor, can you tell me how can I utilize this sensor in my environment to help prevent problems?
The AKCP airflow sensor is designed for systems that generate heat in the course of their operation and a steady flow of air is necessary to dissipate this heat generated. … Read More
Can you please explain how your airflow sensor works?
The way the air flow sensor works is there are two thermistors, one internal and one external. A thermistor changes resistance based on air temperature. The internal thermistor is the … Read More
How accurate is your airflow sensor?
The airflow sensor is not a precision measuring instrument. This device is meant to measure the presence or the absence of air flow. The placement of the sensor is very … Read More
