472 Plug-In Assembly ConfigurationOption 115 is an 8 channel high voltage actuator which can be used to switchvoltages up to 252 volts RMS and currents up to 2 amperes peak. Each channel consistsof an individually fused and protected normally open dry relay. Contacts areopened only on command or on loss of power.Each channel can be closed individually or any combination of channels can be closedsimultaneously. In addition, the assembly contains a readback circuit so that thestatus of each channel can be determined. Because of its high voltage capability,you can use the high voltage actuator to switch power line voltages to small motors,alarm bells and lights, motor starters and solenoids.DescriptionAs shown in Figure 134, the high voltage actuator consists of an actuator card, aterminal card and a grounding strap for connecting the assembly to customer (earth)ground.The actuator card consists of 8 identical channels. Each channel can be closed individuallyor any combination of channels on an assembly can be closedsimultaneously. Each channel is individually fused (at 5 amps) and contains an RCnetwork for relay contact protection.At power on, all relays are open. After relays are closed, contacts are opened onlyon command or on loss of power. A maximum of 680 channels can be attached toactuator outputs using 3498A Extenders (five cards in the 3497A plus 10 cards ineach of eight extenders).Artisan Technology Group - Quality Instrumentation ...
