DAQM910A

DAQM910A is a low voltage 20-channel armature multiplexer (2/4-wire) module for DAQ970A and DAQ973A. It is a versatile multiplexer for general-purpose scanning. It combines dense, multi-function switching with 80-channel/second scan rates to address a broad spectrum of data acquisition applications. The DAQ970A/DAQ973A can combine high and low-voltage signals into a single mainframe. The DAQM910A provides enhanced voltage protection to ensure that high voltage signals from the backplane will not be allowed on the DAQM910A user channels. If a high voltage signal, >±40Vpk, is detected, then the backplane switches open automatically in less than 15ms. Two- and four-wire channels can be mixed on the same module. To support this module, the DAQ97XA mainframe must have firmware revision 03.00 or above.

• Two- and four-wire scanning
• Built-in thermocouple reference junction
