PCI Switching Solutions

Pickering Interfaces expanded its range of PCI switching solutions with the introduction of seven new PCI cards and the expansion of an eighth card. The expansion includes programmable and precision resistors, general-purpose relays, high-density matrices, and multiplexers.

The 50-293 PCI programmable resistor and relay card offers two or four programmable resistor channels. An optional eight single pole, double throw (SPDT) relays can be used for general-purpose switching. Each resistor can be programmed with resistance calls that set the module’s resistance to a ±1% resolution accuracy and the ability to read back the resistance setting to 0.3%. Depending on the version, the resolution is 0.25 to 2 Ω and the resistance is up to 131 kΩ.

The expanded 50-297 PCI precision resistor card family increases the versions offered from six to 42. Each version provides a choice of the number of resistor channels, the resistance range, and the resistance setting resolution. Depending on the version, the resolution is from 0.125 to 2 Ω and the resistor counts from three to 18. Resistor values up to 1.51 MΩ can be simulated and accuracy is ±0.2% resolution.

Two PCI general-purpose 2-A relay cards were also introduced. Model 50-131 provides 16 or 26 single pole, double throw (SPDT) relays. Model 50-132 provides 16, 32, or 39 SPST relays, each rated at 2 A and featuring up to 60-W hot switch power.

Pickering’s PCI 2-A 1-pole high-density matrix solutions include three models. The 50-527 is a 32 × 2, one-pole matrix; the 50-528 offers 32 × 4 or 16 × 4 configurations; and the 50-529 offers 16 × 8 and 8 × 8 configurations.

The 50-635 PCI low-cost electromechanical relay (EMR) multiplexer (MUX) system has a variety of different configurations ranging from a 64:1 single-pole MUX to a quad 8:1 two-pole MUX. All the PCI relay cards use high-quality EMRs and standard D-type connectors.
