DAQM907A multifunction module
This module combines two 8-bit ports of digital input/output, a 100 kHz totalizer, and two ±12 V analog
outputs (DAC). For greater flexibility, you can read digital inputs and the totalizer count during a scan. Use
this module to sense status and control external devices such as solenoids, power relays, and microwave
switches.
Digital Input/Output (DIO)
The DIO consists of two 8-bit ports with TTL-compatible inputs and output. The open-drain outputs can
sink up to 400 mA. From the front panel, you can read data from only one 8-bit input port at a time. From
the remote interface, you can read both ports simultaneously as a 16- bit word only if neither port is in the
scan list.
Totalize Input
The 26-bit totalizer can count pulses at a 100 kHz rate. You can configure the totalizer to count on the
rising edge or falling edge of the input signal. A TTL high signal applied to the terminal enables count-
ing and a low signal disables counting. A TTL-compatible low signal applied to the terminal enables
counting and a high signal disables counting. The totalizer only counts when both terminals are enabled.
Move the Totalize Threshold jumper to the “AC” position to detect changes through 0 V. Move the jumper
to the “TTL” position (factory setting) to detect changes through TTL threshold levels.
