Read/write benchmark timing

The following benchmarks are provided for reference only and were obtained with a single Switch & Sense 8

on a 500 MHz Pentium III running Windows 98 Second Edition. Performance figures can vary based on system

configuration.

Read timing reflects the total time to execute one read operation using the input functions provided in the

interface DLL. Write timing reflects the total time to execute one write operation using the output functions

provided in the interface DLL. The "write time" specified in the table below is the time to assert the relay

control line from the software interface.

Write timing

Throughput

20 mS typical

Relay set

10 mS (write time) + 10 mS (operate time) = 20 mS

Relay clear

10 mS (write time) + 5 mS (release time) = 15 mS

Read timing

Throughput

20 mS typical

Environmental

Operating temperature range

0 to 70 °C
