2.2.64AO 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.

2.2.78DO 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.
