FEATURES
The modular design of the QRS, as with all INFI 90 modules,
allows for flexibility when you are creating a process manage-
ment strategy. It brings analog and digital signals into the sys-
tem and outputs analog and digital signals to the process.
The QRS accepts digital signals of 24 VDC, 125 VDC and
120 VAC. Individual voltage and response time jumpers on the
module configure each input. Selectable response times (fast or
slow) for DC inputs allow the INFI 90 system to compensate for
process field device debounce time. It outputs 24 VDC digital
signals that can sink 250 mA.
