MultiMux Multiplexer

Over-Voltage Protection (OVP) on all instrument channels
The MultiMux is available in 2 versions, one that provides 16 channel by 4-wire switching (or 32 channel by 2-wire switching), a second that provides 16 channel by 6-wire switching (or 48 channel by 2-wire switching). Both products include integrated OVP on all channels thereby providing increased system reliability in areas prone to lightning or other transients. The channel switching mode is controlled by an easily accessible board mounted switch.

Low contact resistance relays provide compatibility with a wide range of instruments, including vibrating wire, resistance strain gage, thermocouples, linear potentiometers and 4-20mA, among others.

Two control inputs provide for activating the MultiMux and then advancing through the channels. Logic levels for either the enable or clocking input can utilize 5V to 12V logic input, with a maximum input of 16V. The control inputs are compatible with a wide variety of control modules including those manufactured by Campbell Scientific, Sutron and Datataker. Contact Canary Systems® for MCU support from other manufacturers.

Description

Transient protection on the control inputs provides high reliability from electrical transients whether ESD or lightning. The power inputs are also equipped with transient protection and reverse-polarity protection.

The MultiMux also includes support for “Daisy-Chain” operation, where control inputs are shared amongst several MultiMux’s (up to 8). The sequence of each MultiMux in the Daisy Chain is easily configured using a board mounted switch.

All components have been selected for ultra-high reliability and function in demanding environments that may include high heat, humidity and/or dust.

The MultiMux may be packaged directly into the Automatic Data Acquisition System (ADAS) enclosure or installed in a variety of standard enclosures. Contact Canary Systems® for enclosure and cable entry options.

The complete list of features and specifications is detailed on the MultiMux Data sheet.
