3.5.2.3 Muting Device Hookup
The Module provides supply voltage, if required, and input
connections for the muting devices. One or two pairs of
muting devices (typically sensors or switches) must be
used; these pairs are designated M1-M2 and M3-M4. The
M1 and M3 inputs are PNP (sourcing). The M2 and M4
inputs are NPN (sinking). Also available are terminals to
supply power (+24V dc) to the muting devices, which are
labeled “+24V dc” and “0V dc.”
The current draw of all devices must not exceed 500 mA.
