PS2001L Power Supply set to isolate mode
FIGURE 2.
Figure 2 shows a 2-channel intercom system using a PS2001L Power Supply set to
isolate mode. In isolate mode, each intercom channel is a separate party line, and total
current for each channel is limited to 1 amp. Note, both WM1000 and WM2000
stations may be connected, depending on each locations need to communicate with
one or two channels. WM1000 stations may be connected to either channel one or
two. Also note, locally powered stations may be connected. This is recommended
when stations are installed at remote locations. Since the PS2001L provides
termination for the intercom channels, no user-installed termination is required. For
WM1000 connection details, refer to Figure 6, for WM2000, refer to Figure 7.
