Our RJ-45 single Dry Contact Sensor is a switch type sensor, so it does not measure voltage, it is either on or off. You can configure this as either an … Read More
Regarding your single dry contact RJ-45 sensor, when this is used as an output, the documentation says that Pin 2 (I/O) can source up to 20mA, so how much current can be taken from Pin 1 ? the 5V supply and how much current will Pin 2 sink?
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
Is it possible to setup my RJ-45 dry contact sensor as a relay, If so, how do I do that?
Yes, You can use one of our RJ-45 dry contact sensors in the any of the 8 ports to drive a relay and a temperature sensor to trigger the output … 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
