2.2.6 4AO Analog Output Board
The 4AO Analog Output Board (P/N 815-3030) (Fig-
ure 2-13) is configured with four analog output connec-
tions that provide a variable voltage signal to any of four
analog devices that may be controlled by a single E2. Two
4-20mA outputs are provided for channels 1 and 2. The
4-20mA outputs provide a variable current for applications
that are either externally powered or that require power
from the 4AO board.
The previous generation 4AO Analog Output Board,
(P/N 810-3030) (Figure 2-14) is configured with four ana-
log output connections that provide a variable voltage sig-
nal to any of four analog devices that may be controlled by
a single E2.
2.2.7 8DO Digital Output Board
and PMAC II Anti-Sweat Controller
For control of anti-sweat heaters, Retail Solutions sup-
plies the 8DO Digital Output board (P/N 810-3050). The
8DO has eight outputs which may pulse up to 150mA at
12VDC.
Since the 8DO is primarily designed to control anti-
sweat heaters, the 8DO is the heart of Retail Solutions’
Pulse Modulated Anti-Sweat Control (PMAC II) panel.
The PMAC II (P/N 851-1000) provides 16 channels of
anti-sweat control circuitry. The PMAC II panel combines
the 8DO with high-capacity relays in a single enclosure,
providing 256 total amps of anti-sweat heater operation.
The 8DO is shown in Figure 2-15. The PMAC II is
shown in Figure 2-16.
