NI SCXI -1175 Specifications
TM 196 × 1 Relay Multiplexer This document lists specifications for the NI SCXI-1175 196 × 1 multiplexer relay module. All specifications are subject to change without notice. Visit ni.com/manuals for the most current specifications. Topologies ...................................... 1-wire 196 × 1 multiplexer 2-wire 95 × 1 multiplexer 2-wire 98 × 1 multiplexer Refer to the NI Switches Help for detailed topology and pinout information. Caution Modules that can connect to a common high-voltage analog backplane derate to their lowest common voltage rating. Refer to the NI Switches Getting Started Guide for more information. Caution The switching power is limited by the maximum switching current, the maximum voltage, and must not exceed 60 W, 62.5 VA. Maximum switching power (per channel)....................................60 W, 62.5 VA (DC to 60 Hz) Maximum total current....................1 A (switching or carry) Note When routing signals through the SCXI High-Voltage Analog Backplane (HVAB), the maximum total current will be 0.5 A. 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. DC path resistance Initial Through front panel................8 Mhz Channel-to-channel isolation (50 termination) Each relay in the NI SCXI-1175 is shared by two channels. Refer to Table 4 for a list of channel pairings. 1-wire channels in different relays 10 kHz ....................................>90 dB 100 kHz ..................................>70 dB 1 MHz.....................................>50 dB 1-wire channels in the same relay 10 kHz ....................................>75 dB 100 kHz ..................................>55 dB 1 MHz.....................................>35 dB 2-wire channels 10 kHz ....................................>95 dB 100 kHz ..................................>75 dB 1 MHz.....................................>55 dB Open channel isolation (50 termination) 10 kHz.........................................85 dB 100 kHz.......................................65 dB 1 MHz .........................................48 dB Expected relay life Mechanical ................................. 1 × 108 cycles Electrical 10 VDC, 100 mADC resistive............... 2.5 × 106 cycles 10 VDC, 1 ADC resistive ...... 1 × 106 cycles 30 VDC, 1 ADC resistive ...... 5 × 105 cycles 60 VDC, 1 ADC resistive ...... 1 × 105 cycles Note The relays used in the NI SCXI-1175 are field replaceable. Refer to the NI Switches Help for information about replacing a failed relay. Trigger Characteristics

Weight............................................. 755 g (1 lb 11 oz) Dynamic Characteristics
Relay operate time Typical ........................................1 ms Maximum....................................3.4 ms Note Certain applications may require additional time for proper settling. For information about including additional settling time, refer to the NI Switches Help. Maximum scan rate .........................120 channels/s 1 To ensure the typical thermal EMF, power down all relays and avoid pulsing high currents near the channels you are measuring. For more information about powering down latching relays, refer to the Power Down Latching Relays After Debounce property in NI-SWITCH or the Power Down Latching Relays After Settling property in NI-DAQmx.

See the previous safety caution. Note When using either the SH200LFH-4xDB50F-S or SH200LFH-BARE WIRE cable with the NI SCXI-1175 in the 2-wire 98 × 1 topology, CH95, CH96, and CH97 will have lower RF performance than the other 95 channels because they are not in twisted pairs in the cable. To avoid using these channels, NI-SWITCH has support for a 2-wire 95 × 1 topology that does not include CH95, CH96, and CH97. 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. © National Instruments Corporation 3 NI SCXI-1175 Specifications Table 3.
