68SR1
3U OpenVPX Solid-State Power Controller Relay Board Solid-State Power Switch Output; 3-Modules supporting up to 4-Channels each
The 68SR1 3U OpenVPX configurable open systems architecture motherboard can be configured with up to three NAI Solid-State Power Controller/Relay (switching) modules, each capable of supporting up to four isolated high current & voltage discrete output switching channels. External command and control is provided via one PCIe x1 backplane interface and one Ethernet ports, which can be factory configured to support 10/100/1000BASE-T or 1000BASE-X. Ideally suited for rugged Mil-Aero applications, the 68SR1 delivers off-the-shelf solutions that accelerate deployment of SWaP-optimized systems in air, land and sea applications.
The board platform provides support for (3) different NAI solid-state power controller switching relay function module types:

| Module Characteristics Module Type |
Module ID: | Channels: | Description / Default Type, Voltage Range @ Current (max./Ch): | |
| SW1 | 4 | Normally Open (NO), Low-V, ±100V @ 6A continuous | ||
| SW2 | 4 | Normally Open (NO), High-V, ±200V @ 4A continuous | ||
| SW3 | 2 | Normally Closed (NC), Low-V, ±100V @ 3A continuous | ||
| Overvoltage Surge Protection: | 15% Rated VDC max. (clamped) | |||
| Output Mode Format: (programmable per channel) |
Command Output Drive = OPEN or CLOSED | |||
| Channel OPEN Output Impedance: | High-Z (>1 MΩ) | |||
| Channel CLOSED Output Impedance: | < 0.1 Ω | |||
| System Protection: | All output(s) are set to "Default" (at Power-ON and reset). No voltage transients on power-on or power-off. | |||
| Load & Channel Protection: | Short circuit protected. Channel shuts "off" and a flag is set when current exceeds programmable overcurrent setting (max 6A) > 10 ms. Channel over-current reset by control/status register command. |

| Open-Switch Voltage Measurement: | Voltage: LSB = 100 mV; Accuracy: ±1V |
|||
| Closed-Switch Current Measurement: | User can read current of each channel. Current: LSB = 20 mA; Accuracy: ±100 mA (tbd) |
|||
| Parallel Operation: | All channels (within the module) can be paralleled for current share. (tbd) | |||
| Isolation: | Module power source (ISO-GND) and I/O to system ground is ≥500 VDC | |||
| Power: | SW1: 12 VDC / 320 mA (max) (does not include source powered load) SW2: 12 VDC / 320 mA (max) (does not include source powered load) SW3: 12 VDC / 160 mA (max) (does not include source powered load) |
