NI PXI-2586 Specifications
10-SPST Relay Module
This document lists specifications for the NI PXI-2586 general-purpose relay module. All specifications are subject to change without notice. Visit ni.com/manuals for the most current specifications.
Note: This document also includes Japanese text.
[!] Caution: When hazardous voltages (>42.4 Vpk/60 VDC) are present on any relay terminal, safety low-voltage (≤42.4 Vpk/60 VDC) cannot be connected to any other relay terminal. Refer to the NI Switches Help for detailed topology information. Specifications characterize the warranted performance of the instrument under the stated operating conditions. Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 °C. Typical specifications are not warranted. All voltages are specified in DC, ACpk, or a combination unless otherwise specified. [!] Caution: Refer to the Read Me First: Safety and Electromagnetic Compatibility document for important safety and electromagnetic compatibility information. To obtain a copy of this document online, visit ni.com/manuals, and search for the document title. [!] Caution: To ensure the specified EMC performance, operate this product only with shielded cables and accessories. All input characteristics are DC, ACrms, or a combination unless otherwise specified. [!] Caution: The switching power is limited by the maximum switching current and the maximum voltage. For AC systems, switching power must not exceed 3 kVA. For maximum DC switching power, refer to Figure 1. Note: Switching inductive loads (for example, motors and solenoids) can produce high voltage transients in excess of the module's rated voltage. 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". Figure 1: Maximum Switching Power for DC Loads (per channel). This graph plots DC Voltage on the x-axis (10V to 300V) against Contact Current (Amps) on the y-axis (0.1A to 10A). It shows that as DC Voltage increases, the allowable Contact Current decreases, illustrating the power limit. Figure 2: Maximum Current for Ambient Temperatures. This graph plots Ambient Temperature (°C) on the x-axis (0°C to 55°C) against Maximum Current (Amps) on the y-axis (0A to 14A). It shows that maximum current capacity decreases as ambient temperature rises above 23°C, with a specific derating curve for temperatures above 45°C. DC path resistance typically remains low for the life of the relay. At the end of relay life, the path resistance rapidly rises above 100 mΩ. Load ratings apply to relays used within the specification before the end of relay life. [!] Caution: A total power load greater than 400 A² × channels will damage the NI PXI-2586 under certain conditions. Load derating is dependent on the sum of the current squared of each channel simultaneously carrying a signal. The result must be less than 400 A² × channels. The following formula represents this calculation: ∑ (I²channel N) ≤ 400 A² × channels Note: When operating at ambient temperatures >45 °C, refer to the derating chart in Figure 2 for the maximum allowed current per channel. 1 channel carries 8 A while 5 channels carry 6 A (1 × 8²) + (5 × 6²) = 244 A² × channels The module in Example 1 is acceptable since the result of the calculation is less than 400 A² × channels. 5 channels carry 5 A while 4 channels carry 9 A (5 × 5²) + (4 × 9²) = 449 A² × channels The module in Example 2 is not acceptable and will damage the module under certain conditions. Note: Certain applications may require additional time for proper settling. Refer to the NI Switches Help for information about including additional settling time. Note: The relays used in the NI PXI-2586 are field replaceable. Refer to the NI Switches Help for information about replacing a failed relay. For AC load contact lifetime, refer to Figure 3. Figure 3: Contact Life for Resistive AC Load (Typical). This graph plots Breaking Capacity (kVA) on the x-axis (0.0 kVA to 4.0 kVA) against Operations (in powers of 10, from 104 to 107) on the y-axis. It illustrates that higher breaking capacity leads to a significantly reduced number of operational cycles before failure. Note: The NI PXI-2586 can recognize trigger pulse widths less than 150 ns by disabling digital filtering. For information about disabling digital filtering, refer to the NI Switches Help. Note: Refer to Figure 2 for operating temperatures >45 °C. Figure 4: NI PXI-2586 Power-On State. This diagram shows the internal relay configuration at power-on. Channels CH0 through CH9 are each connected to a relay (K0 through K9) which is internally connected to a common terminal (COM0 through COM9, respectively). Figure 5: NI PXI-2586 Connector Pinout. This diagram illustrates the pin assignments for the 20-position Positronic GMCT series plug. It shows the mapping between connector pin designators (e.g., C, F, K, N) and the module's channels (CH0-CH9) and common terminals (COM0-COM9). Note: Letters in parentheses reference the pin designators of the connector. Note: For topology-specific connection information, refer to your device in the NI Switches Help. Visit ni.com for more information about the following accessories. [!] Caution: You must install mating connectors according to local safety codes and standards and according to the specifications provided by the connector manufacturer. You are responsible for verifying safety compliance of third-party connectors and their usage according to the relevant standard(s), including UL and CSA in North America and IEC and VDE in Europe. * Additional cover or enclosure required. See the previous safety caution. † The Positronic Connector and backshell require Mating pins to front connector. Mating pins to front connector must be purchased separately. Note: When using third-party accessories with the NI PXI-2586, always observe safety guidelines. For information about how to safely build a third-party connector and backshell, refer to the NI PXI-2585/2586 Connector and Backshell Kit Installation Guide located at ni.com/manuals.
