Smart input cable 4-20 mA S-CIA-CM14
The smart input cable 4-20 mA S-CIA-CM14 allows to connect sensors providing a signal 4-20 mA to weather stations de the mark HOBO.
The smart cable is a cable used to transmit analogue electrical signals de 4 to 20 milliampers (mA) from a measuring or checking device to other electronic equipment.
It has input not switched and one switched input with a battery saving capacity of digital filtering, and can be used in indoor environments and external.
By using this type of cable, smart transmitters can transmit precise data and reliable for industrial processes in an efficient and efficient manner real-time monitoring the operating conditions of the equipment.
Smart input cable 4-20 mA S-CIA-CM14 interfaces with any sensor providing a signal 4-20 mA to connect to hOBO compatible stations with the smart sensors.
This is it adapter includes both input not switched and one switched input saving the battery that extends the life of external batteries.
It also provides trigger signal to control the power supply of connected external sensors, while offering a digital filtering which improves the accuracy of measurements with 32 readings/sample and a noise rejection of 60 Hz.
The cable allows the transmission of measurement signals in a way bidirectional, which means that the data can be sent to and received from the measuring device.
In addition, this cable also has a digital communication function to recover additional information, such as the calibration, identification of the apparatus alarms and diagnostics.
