National Instruments 777518-502 Counter Module for FieldPoint

Part Number 777518-502 is the identifying part number for the National Instruments FP-CTR-502 Counter Module for FieldPoint. The 777518-502 features 12 channels, divided into 8 count and 4 gate channels. The input is sourcing type with a range of 5 to 30 VDC. They are also compatible with TTL devices and other 5, 12, or 24 VDC devices. The input bandwidth for both the count and the gate inputs is 50 KHz. However, the count inputs can have an input bandwidth of 200 Hz with a software-enabled lowpass filter. The minimum input pulse width is 10 µs at 50kHz and 2.5 ms at 200 Hz. 

On the other hand, the 777518-502 has 4 output channels of sinking type and with an output range of 5 to 30 VDC. They are also compatible with a wide range of devices like the inputs. The supply voltage is 5 to 30 VDC, and this is user-provided. The maximum output current per channel is 1 A while it is 4 A across all channels. The output bandwidth is 16 kHz for a current flow ≥3.2 mA. The 777518-502 draws 800 mW of power from the network module. There is no channel-to-channel isolation in this device. The device weighs 5.0 oz and has green POWER and READY indicators along with 15 input/output 

The 777518-502 is recommended for use in between the temperature range of –40 to 70 °C at a relative humidity of 10 to 90%. On the other hand, it can be stored at a much wider range of –55 to 85 °C. Note that the device is designed for indoor use only and they should be mounted inside a sealed enclosure for outdoor use. Likewise, the maximum altitude for the operation of the module is 2000 m and as altitudes get higher, the isolation voltage ratings must be lowered. The module meets the requirements of the following safety standards as an electrical equipment for measurement, control, and laboratory use:  IEC 61010-1, EN 61010-1, UL 3121-1, UL 61010C-1, CAN/CSA C22.2 No. 1010.1.
