ND810 Process Digital Input¶
ND811 Process Digital Output¶
Introduction¶
The ND810 and ND811 optically coupled digital input/output modules are designed for industrial and marine applications for interfacing ND computers to relays, lamps, and on/off contacts. Each module occupies one standard I/O slot.
Features¶
- 12 bits in — 16 bits out
- All lines optically coupled
- Internal programmable Compare Register
- Contact debounce logic
- Input signal conditioning
Product Description¶
The ND810 Input Module contains a programmable 12-bit Compare Register. If the input data pattern and the Compare Register differ, an interrupt will be generated.
The ND811 Output Module does not generate any interrupts. 16 bits of data are simply loaded into a holding register and will immediately be available at the output terminals.

SPECIFICATIONS¶
ND810 Input Module¶
- Number of digital inputs: 12
- Operating temperature: 0 - 55°C
- Operating relative humidity: 0 - 90% no condensation
Electrical Characteristics¶
| Min. | Typ. | Max. | |
|---|---|---|---|
| VIT = Transition Voltage | 5.5V | ||
| VIH = High level input voltage | 7.8V | ||
| VIC = Low level input voltage | 1.7V | ||
| IIH = High level input current, @VI = 12V | 9.3mA | ||
| IIL = Low level input current, @VI = 1.5V | 0.25mA | ||
| @VI = -15V | -10mA |
For VI > 12V, a limiting resistor — RE — must be included in external equipment.
Absolute Maximum Ratings¶
Voltage between corresponding input terminals: -15V, +13.5V.
NOTE: DXo, DX1
- D = Data
- X = Data bit #
- Index 0 = -terminal
- Index 1 = +terminal
Continuous Common Mode voltage between computer ground and input terminals: ± 30V.
Switching Characteristics¶
Delay from any change in input to interrupt: 4 ms ± 20%. A change in any input line must exceed the 4 ms in order to generate the interrupt. This constitutes the contact debounce logic.
ND811 Output Module¶
- Number of digital outputs: 16
- Operating temperature: 0 - 55°C
- Operating relative humidity: 0 - 90% no condensation
Electrical Characteristics¶
| Min. | Typ. | Max. | |
|---|---|---|---|
| VOL = Low level output voltage, @IOL = 30mA | 0.9V | 1V | |
| IOL = Low level output current | 30mA | 80mA | |
| IOH = High level output current, @VOH = 30V | 1µA |
Absolute Maximum Ratings¶
- Voltage at terminal DXi relative DXo: -5V, +30V.
- Continuous common mode voltage between computer ground and output terminals DXo or DXi: ± 30V.
- Maximum continuous output current: 100 mA. Inductive load should be properly bypassed by a diode.
Switching Characteristics¶
Switching time depends upon load resistance — RE — and pullup voltage VC. Typical ON and OFF switching times for RE: 1kΩ and VC: 30V are less than 30 µs.
