RT-VWSB Switching Box

New

VERSATILE

ROBUST ENCLOSURE

ROTARY SWITCHES

The RT-VWSB is a robust switching box used to group multiple sensors in a single location providing a convenient mean of taking readings.

Description

The RT-VWSB consists of a fiberglass enclosure containing terminal blocks, rotary switches, cable input connectors and sockets for portable readout connection.

The switching box can handle up to twenty 4-conductor sensors, and allows lightning protection to be added for each of these conductors.

The RT-VWSB may be fitted with an RT-MUX multiplexer for use with a SENSLOG 1000X data acquisition system. This option is available in 8- or 16-channel versions only. Please refer to the SENSLOG 1000X brochure for more information about the RT-MUX. Connection to another type of data acquisition system — not requiring the RTX-MUX— is also possible through a 40-pin adapter cable (avail able upon request).
