National Instruments 777459-11 Digital Input Module for SCC
Part Number 777459-11 is the identifying part number for the National Instruments SCC-DI01 Digital Input Module for SCC. This single-channel, optically isolated input module can measure AC and DC digital signals up to values of 30 VDC or 30 VAC.
The digital logic levels for the 777459-11 are defined as follows: a maximum of ±1 V DC or peak AC is considered input low voltage, a minimum of ±2 VDC and a maximum of ±30 VDC are considered input high voltage (DC), and a minimum of 4 Vrms and a maximum of 30 VAC is considered input high voltage (at 1 KHz AC). The input current for 5 V and 24 V input is 1.5 mA and 7.0 mA respectively. The propagation delay from low to high is 10 µs and from high to low is 250 µs. Lastly, the rise time and fall time have a maximum value of 10 ns.
The 777459-11 measures (3.50 in. × 1.15 in. × 0.73 in.) in physical dimensions and weighs 1.0 oz. For I/O purposes, it uses a 20-pin right-angle male connector and a 2-pin screw terminal. Likewise, the field-wiring diameter supported by the module is 28 to 16 AWG. The maximum working voltage, which is the signal voltage plus the common-mode voltage for both channel-to-earth and module-to-module is 42 V and falls under the Installation Category II. The module consumes a maximum digital power of 61 mW.
The 777459-11 should be used in the suggested temperature range of 0 °C to 50 °C with a relative humidity of up to 10% to 90%. But, it may be kept in storage between -20 and 70 degrees Celsius. Keep in mind that the device can only be used indoors; to use it outside, it needs to be put within a sealed enclosure. Furthermore, the device should be operated within a maximum altitude of 2000 m. The device satisfies the following safety requirements: IEC 61010-1, EN 61010-1, UL 3101-1, UL 61010B-1, and CAN/CSA C22.2 No. 1010.1. These requirements are for electrical equipment intended for measurement, control, and laboratory usage.
