Input

Caution This module is rated for Measurement Category I and intended to carry signal voltages no greater than 150 V. This module can withstand up to 800 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 or 230 V AC.
Caution When hazardous voltages (>42.4 Vpk/60 V DC) are present on any relay terminal, safety low-voltage (≤42.4 Vpk/60 V DC) cannot be connected to any other relay terminal.
Caution The switching power is limited by the maximum switching current and the maximum voltage, and must not exceed 60 W, 62.5 VA.
Maximum switching voltage[1]1 Switching inductive loads (for example, motors and solenoids) can produce high-voltage transients in excess of the rated voltage of the module. Without additional protection, these transients can interfere with module operation and impact relay life. For more information about transient suppression, visit ni.com/info and enter the Info Code induct.

Module Load Derating at >25 °C

Load derating is dependent on the ambient temperature and the sum of the current squared of each channel simultaneously carrying a signal. The result must fall within the shaded region of the following figure. The following examples represent this calculation:

Example 1: Five channels carry 4 A while ten channels carry 2 A.

(5 × 42) + (10 × 22) = 120 A2 × channels

Example 1 can be used at ambient temperatures between 0 °C and 50 °C.

Example 2: Six channels carry 5 A while ten channels carry 2 A.

(6 × 52) + (10 × 22) = 190 A2 × channels

Example 2 can be used at ambient temperatures between 0 °C and 41 °C.
