National Instruments cFP-CTR-500 Counter Module for Compact Fieldpoint

The cFP-CTR-500 (Part number: 777318-500) is a sinking Counter Module for Compact FieldPoint. Each information channel has one info terminal, VIN. Each channel additionally has VSUP and COM terminals that can supply capacity to certain devices. The user can associate the eight tally input channels and four door input channels to gadgets with sourcing outputs. The cFP-CTR-500 has sinking inputs, which implies that the VIN terminal gives a way to normal. The NI cFP-CTR-500 info channels are optically segregated from whatever is left of the FieldPoint bank and have current-restricting hardware. All the info channels are referenced to the C and COM terminals. At the point when the voltage crosses over VIN and COM is 10 V or more noteworthy, current moves through VIN and turns on the opto-isolator, enrolling in an ON state for the channel. At the point when the voltage crosses over VIN and COM is 6 V or lower, current does not move through VIN and the divert is in the OFF state. The user should guarantee that the sourcing-output gadgets have OFF state spillage streams of under 0.2 mA, so they do not create false ON state readings. The cFP-CTR-500 has a power requirement of 800 mW from the network module.

The eight counters on the cFP-CTR-500 Counter Module all have 16-bit resolution. There are both sinking inputs and sourcing outputs on the module, which are compatible with 12 and 24 VDC models. The device has an input range of 10 to 30 VDC. In addition, the NI cFP-CTR-500 has internally cascadable counters. The module also has the useful feature of being hot swappable.

The cFP-CTR-500 weighs 4.0 oz, and measures 4.2 x 4.3 x 3.6 in. in physical dimensions. It has recommended operating and storage temperature ranges of –40 to 60 °C and –55 to 85 °C respectively, a non-condensing relative humidity range of 10 to 90% RH, random and sinusoidal operating vibrations of 5 grms and 5 g respectively–all at a frequency range of 10 to 500 Hz. Additionally, the NI device is designed to comply with the following electrical safety standards: IEC 61010-1, EN-61010-1, UL 61010-1, and CSA 61010-1.
