RT-MUX 16/32 – Signal Multiplexer
UP TO 32 CHANNELS
RELIABLE AND COST EFFECTIVE
VERY LOW POWER CONSUMPTION
The RT-MUX-16/32 is a compact, robust and reliable signal multiplexer. The cost effective RT-MUX can be used in daisy-chain configuration for additional economy
The RT-MUX-16/32 Signal Multiplexer is a cost effective way to expand the amount of channels a single datalogger can handle. The use of this multiplexer enables the user to lower the overall cost of a telemetry system on a project by maximizing the use of a single datalogger and minimizing the amount of cable required when used in a junction box.
It can multiplex up to 32 sensors (with 2 conductors each) or 16 sensors (with 4 conductors each). Its modular design offers the possibility to add an effective surge protection that will protect every channel against lightning or EMI/RFI.
The compact size of the RT-MUX-16/32 allows the user to save space within a switchbox or within an Automatic Datalogging System (ADAS), and its low power consumption won’t drain a standalone battery-powered data acquisition system.
RT-MUX-16/32 can be used in daisy-chain configuration. They can operate in a serial layout; An economic feature to minimize the cable length required to link multiple multiplexers to the same datalogger.
The RT-MUX-16/32 is the champion of low power consumption with a quiescent current of less than 20uA. When powered to take a measurement, the RT-MUX-16/32 has the capability to power multiple pairs of sensors individually or the full multiplexer.
