Smart Array 6404 Ctr. PCI, 2CH, Daughter Card 32-bit nonisolated dc output module. Provides 32 program- controlled current sink dc outputs Smart Array 6404 Ctr. PCI, 2CH, Daughter Card for use with an external power supply. The outputs are single-wire, nonisolated, open collector Darlington switches used for controlling relays, sole- noid values, indicators, heaters, and other devices. The out- puts provide CMOS logic levels and feature a common output fuse. Also features Zener diode output protection from exces- sive supply voltages. Smart Array 6404 Ctr. PCI, 2CH, Daughter Card -YA 32-bit nonisolated dc output module (TTL Compatible). Provides 32 TTL-compatible, program-controlled dc sink outputs that are single-wire, nonisolated, open collector switches for use with customer-supplied field power supplies and pull-up resistors. Protection against excessive field sup- ply voltages is provided by Zener diodes across each output. Smart Array 6404 Ctr. PCI, 2CH, Daughter Card Nonisolated dc one-shot output module. Provides 16-program controlled current sink dc outputs for use with an external field power supply. Outputs are nonisolated, single-wire, one-shot, open collector Darlington switches used for operating devices that must be activated for only a short duration (i.e., solenoid, values, and relays). The outputs provide Smart Array 6404 Ctr. PCI, 2CH, Daughter Card logic levels for noise immunity and reliability. Also features Zener diode out- put protection from excessive field voltage overloads. Smart Array 6404 Ctr. PCI, 2CH, Daughter Card 8-bit isolated dc output module. Provides eight program-con- trolled current sink outputs for use with an external power sup- ply. Outputs are isolated, three-wire, open collector Darlington switches used for controlling solenoid values, relays, indicators and heaters, where isolation from the controlled process must be maintained. The outputs provide CMOS logic levels and feature individual output indicators. Smart Array 6404 Ctr. PCI, 2CH, Daughter Card 8-bit isolated ac output module. Provides eight program- controlled ac outputs. Outputs are transformer-isolated, three-wire switches used for switching ac line voltages to operate ac relays, solenoids, lamps, pumps, blowers, alarms, etc. Features include individual output status indicator and fuse protection for the circuit board etch.
