2.3.2
NEXSYS® components can be specified alongside electromechanical switches or separately in Compact (See Figure 2.1.1-B) or High Capacity (See Figure 2.1.2-B) bodies. Switch/indicator bodies with NEXSYS components are covered by MIL-PRF-22885/108 and /113. NEXSYS components cannot be used with Short bodies.
Figure 2.3.2-A below lists only the NEXSYS components that can be specified internal to a Compact and/or High Capacity body. A brief description of the functionality of each component follows. See NEXSYS Component Technology Technical Specification Guide (TS-NCT-17) for a complete description of each NEXSYS component.
| Function | Description | 
|
|
|
|---|---|---|---|---|
| Data Conversion | ||||
| ARINC 429 Signal Converters | Autonomous ARINC 429 receivers with the protocol logic necessary to capture and convert a specified data-word to discrete output(s), controlled by the decode of a single label and bit, multiple-bits, or multi-bit Binary Decode (BD). |
|
|
|
| Signal Switching/Control | ||||
| Defined Logic | Digital electronic device that performs Boolean logic gate operations AND, OR, NOT, NAND, NOR, XOR, XNOR, as well as BUFFER. |
|
|
|
| Solid State Relay | Normally Open (NO) and Normally Closed (NC) solid-state relays available individually (SSR) or in a combination of four (SSRCH). The bidirectional inputs are polarity insensitive, and the device performs buffered switching with optical isolation between inputs and outputs. |
|
|
|
| State Control | ||||
| Electronic Latch | Electronic latching with multiple trigger modes to activate orthogonal switching (flip-flop) between two known states and a 1Hz blink output. |
|
|
|
| Electronic Rotary | Electronic rotary control that performs incremental switching through a loop of up to four latched output states, controlled by input level transitions. |
|
|
|
| Timing | ||||
| Pulse/Timer | Dual-channel edge detector and pulse generator with independent channels to perform stable retriggerable/resettable one-shot operation for fixed timing applications. Pulse-width output timing options range from 125 ms to 20 sec. |
|
|
|
| Time Delay
|
Time-delay output, controlled by input triggers or power-up. Output timing options range from 125 ms to 4 hrs. |
|
|
|
| Square Wave Oscillator
|
Oscillating output controlled by input triggers or power-up. Frequency (cycles/sec) and Period (sec/cycle) options range from 0.25 Hz (4 sec) to 500 Hz (0.002 sec). |
|
|
|
| Sensing | ||||
| Voltage Sensor | Direct Current (DC) voltage sensor performs undervoltage and overvoltage detection to trigger the output. Sensed-voltage (VSD1) setpoint options range from +1 to 48 VDC, and sensed-low voltage (VSD2) setpoint options range from 50 mVDC to 1000 mVDC (+1 VDC). |
|
|
|
| Current Sensor
|
Direct Current (DC), low-side current sensor that performs undercurrent and overcurrent detection to trigger the output. Sensed-current setpoint options range from 10 mA to 1000 mA (1.0 A). |
|
|
|
| Passive | ||||
| Diode Pack | Package of two diodes specified as either commercial (1N6484) or military (JANTX1N5621) grade. |
|
|
|
| Terminal Block | 4-splice configuration for increased wiring efficiency. |
