National Instruments 777459-12 Isolated Digital Input Module.
Part Number 777459-12 is the identifying part number for the National Instruments SCC-DO01 Isolated Digital Input Module. It is a solitary channel, optically disconnected advanced output with a photomask relay and a load resistor. This device can be used with a 5-24 VDC external voltage supply to switch devices such as transistors and solid-state relays. The 777459-12 features a single TTL-compatible output channel. The supply voltage of the module ranges from 5 to 24 VDC. Likewise, the maximum digital power requirement for the module is 69 mW. The propagation delay in the module is 400 μs (typical) for low to high and 300 μs (typical) for high to low. Similarly, the rise and fall time for the module is 120 μs (typical) and 25 μs (typical) respectively. Note that the turn-on time, switching time, and turn-off time for the optical isolator used in the module limits the data rate.
The 777459-12 measures module measures (3.50 in. × 1.15 in. × 0.73 in.) in physical dimensions and weighs 1.0 oz. The field-wiring diameter supported by the module ranges from 28 to 16 AWG. The module features a 20-pin right-angle male connector and a 2-pin screw terminal for I/O connections. The 777459-12 has a maximum working voltage, i.e., the signal voltage plus the common-mode voltage, of 42 V, installation category 2 (for both channel-to-earth and module-to-module). The module is recommended for operation between temperatures of 0 to 50 °C and a relative humidity of 10% to 90%.
On the other hand, it has a storage temperature of -20 to 70 °C. Note that the module is designed only for indoor use and may require mounting inside a sealed enclosure if used in outdoor spaces. Furthermore, the recommended maximum altitude for the operation of the module is 2000 m. The 777459-12 meets the requirements for the safety and electrical equipment for measurement, control, and laboratory use as per the following standards; IEC 61010-1, EN 61010-15, UL 3111-1, UL 6101B-1, CAN/CSA C22.2 No. 1010.1.
