3.9.5.2 Characteristics
3.9.6 Digital Output Solid State Relay AC
3.9.6.1 Functional Description
The Digital Output Solid State Relay AC (DO-SSR AC) allows the
controller to switch high-voltage AC signals to control solenoids, digital
control valves, alarms, and other loads.
The two output terminals behave as a “volt-free” contact and require an
external AC power supply to drive a load.
FIGURE 3-35 illustrates a simplified block diagram of the DO-SSR AC
self powered connections and FIGURE 3-36 illustrates a simplified
block diagram of the DO-SSR AC externally powered connections.
