About These Specifications

Specifications characterize the warranted performance of the instrument under the stated operating conditions. Data in this document are Specifications unless otherwise noted.

Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 °C ambient temperature. Typical specifications are not warranted.

All voltages are specified in DC, ACpk, or a combination unless otherwise specified.

Clean devices and terminal blocks by brushing off light dust with a soft, nonmetallic brush. Remove other contaminants with a soft, lint-free, dampened cloth. Do not use detergent or chemical solvents. The unit must be completely dry and free from contaminants before returning to service.

Cautions

Caution This module is rated for Measurement Category I and intended to carry signal voltages no greater than 70 Vrms/100 Vpk/100 VDC. This module can withstand up to 500 V impulse voltage. Do not use this module for connection to signals or for measurements within Categories II, III, or IV. Do not connect to MAINS supply circuits (for example, wall outlets) of 115 VAC or 230 VAC. Refer to the Read Me First: Safety and Electromagnetic Compatibility document for more information on measurement categories.
Caution In systems that include cards with different maximum voltages, the lowest safety voltage rating as specified on the front of the card applies for the entire system. The system can include all cards in the carrier, and all cards in other carriers that are connected with the NI 2806 expansion bridge.
Caution When hazardous voltages (>42.4 Vpk/60 V DC) are present on any channel, safety low-voltage (≤42.4 Vpk/60 V DC) cannot be connected to any other channel.
Caution Always disconnect or turn off power sources before powering on a chassis.

100 V, 10 mA

5 × 105 cycles

Note Optional 100 Ω series protection resistance, available for the interface cable, increases the expected relay life at higher voltages by protecting the reed relays from the effects of cable and load capacitance. For more information about increasing the life of your relay, visit ni.com/info and enter the Info Code relaylifetime.
Note Reed relays are highly susceptible to damage caused by switching capacitive and inductive loads. Capacitive loads can cause high inrush currents, and inductive loads can cause high flyback voltages. The addition of appropriate protection can greatly improve contact lifetime. For more information about adding protection circuitry to a capacitive load, visit ni.com/info and enter the Info Code relaylifetime. For information about inductive loads, enter the Info Code relayflyback.
