^1Max. expansion: 64 ch (with 8 units connected, using NR-X100W) ^2Protection rating against temporary overvoltage. Do not apply voltage directly from an external source. ^3The time until detection is confirmed varies depending on the acquisition setting and the input signal source resistance. Detection may be disabled depending on the low-pass filter and sampling cycle settings. For details, see P. 5–29. ^4Does not include reference junction compensation accuracy. Specified with an A/D integration time of 20 ms (50 Hz) / 16.7 ms (60 Hz), the low-pass filter set to PASS, averaging set to 2 times, and after the warm-up time has passed and the temperature has stabilized (23°C ±3°C73.4°F ±5.4°F). ^5The buffer memory that can be used by the entire system is limited by the NR-X100W buffer memory. ^6Environment-resistant unit cables can be extended by connecting an environment-resistant unit extension cable. The total length of cables used in the system should be no more than 100 m3.2.8'. The distance between the NR-X100W (or NR-XR01) and environment-resistant measurement units or between environment-resistant remote measurement units should be no more than 60 m196.9'. ^7The sampling cycle and timing vary depending on the various measurement units used in the system. ^8Install the product on the specified mounting sheet metal (OP-88613) for use with ambient temperatures of 80°C176°For higher. ^9Use the product under the condition that the absolute humidity is 85°C185°Fwith 90% RH or less. Avoid sudden temperature and humidity changes to prevent significant condensation and freezing. ^10Testing with a 50 mm1.97"p-p displacement limit used for 5 to 10 Hz.
