Pickering Interfaces intros PXI digital I/O module

CLACTON ON SEA, UK: Pickering Interfaces is expanding its range of PXI products with the introduction of new high performance Digital I/O module.

The 40-413 is a 32 channel Digital I/O module with high current outputs and dual threshold voltage inputs available in three different modules. Typical applications will be found in military, aerospace and automotive function test systems.

The 40-413-001 provides 32 high side output drivers each capable of sourcing up to 2A from an external power supply. The 40-413-002 provides 32 low side drivers each capable of sinking up to 2A to ground. The 40-413-003 includes both high and low side drivers, allowing users the flexibility of supporting systems with mixed configurations where a mixture of high and low side drivers is required or different systems with both types of drive requirements.

Each output is capable of working with 40V power loads and is fully protected against over voltage spikes from inductive loads and short circuits from defective loads. Each output includes thermal protection to automatically shut the driver down when connected to a faulty load.

All models have 32 digital input channels which can compared to two user programmable threshold voltages that make it simple to check that the external inputs are high, low or intermediate voltages. Each input can withstand voltages to greater than 100V. The two variable threshold voltages can be set from 0.3V to 50V with nominally 12.5 mV resolution, allowing the 40-413 to work with all commonly found high voltage I/O applications.
