4AO Analog Output Board
The 4AO Analog Output Board (P/N 815-3030) (Fig-
ure 2-15) 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.

8DO Digital Output Board
and PMAC II Anti-Sweat Controller
For control of anti-sweat heaters, Emerson Retail Solu-
tions supplies the 8DO Digital Output board (P/N 810-
3050). The 8DO has eight outputs which may pulse up to
150mA at 12VDC.
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 Emerson Retail
Solutions’ Pulse Modulated Anti-Sweat Control (PMAC
II) panel. The PMAC II (P/N 851-1000) provides 16 chan-
nels 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.
