Plug-In Assembly Configuration 4571 OPTION 1 101The Option 1 10 assembly consists of 16 mercury-wetted form C (single-pole doublethrow)relays. The assembly has two functional modes: Actuator Mode and DigitalOutput Mode. In the actuator mode, each channel relay can be closed to switchpower to (actuate) multiple external devices. Each relay can safely switch up to 1amp at 100 volts (peak).In the digital output mode, each relay can be set to the Normal Open (NO) position(logical 1) or to the Normal Closed (NC) position (logical 0) to provide an 8-bit or16-bit wide digital output. The assembly uses "bounceless" relays, isolated GateIFlagHandshake lines and + 5V nonisolated internal excitation. The assembly has capa-bility for up to + 100V external excitation and can be configured for open collectoroperation.The actuator can be configured as a 4 x 4 point matrix scanner and additionalassemblies can be added to construct larger matrices. Since the actuator assemblycan switch one amp at 100 volts, it can be used to switch test fixture power orto actuate alarm bells. In addition, the assembly can be used with the 16 ChannelIsolated Digital Inputllnterrupt Assembly (Option 050) to provide an independentdigital inputloutput port.DescriptionAs shown in Figure 124, the Option 1 10 assembly consists of a relay card and aterminal card. The relay card consists of 16 mercury-wetted, Form C (single-poledouble-throw) relays. Each relay can be individually closed (set to the Normal Openposition) or opened (set to the Normal Closed position).In addition, the relay card contains a jumper to select a positive-going (LGT) ornegative-going (HGT) gate pulse, a jumper to select a positive-going (LFL) or negativegoing(HFL) flag pulse, and a jumper to enable or disable the handshake function forthe assembly.Artisan Technology Group - Quality Instrumentation ...
