34907A Multifunction Module<br />
• Two 8-bit Digital Input/Output ports, 400 mA sink, 42 V open<br />
collector<br />
• 100 kHz Totalize input with 1 Vpp sensitivity<br />
• Two 16-bit, ±12 V Calibrated Analog Outputs<br />
• For detailed information and module block diagrams, see page 161.<br />
Use this module to sense status and control external devices such as<br />
solenoids, power relays, and microwave switches. For greater flexibility,<br />
you can read digital inputs and the count on the totalizer during a scan.<br />

34908A 40-Channel Single-Ended Multiplexer<br />
• 40 channels of 300 V single-ended (common LO) switching<br />
• Built-in thermocouple reference junction<br />
• <strong>Switch</strong>ing speed of up to 60 channels per second<br />
• Connects to the internal multimeter<br />
• For detailed information and a module diagram, see page 159.<br />
Use this module for high-density switching applications which require<br />
single-wire inputs with a common LO. All relays are break-before-make<br />
to ensure that only one relay is connected at any time.<br />
