2.2.6 4AO Analog Output Board
The 4AO Analog Output Board (P/N 815-3030) (Figure
2-13) is configured with four analog output connections
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.

2.2.7 8DO Digital Output Board
and PMAC II Anti-Sweat Controller
For control of anti-sweat heaters, Retail Solutions supplies
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 antisweat
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.
