MODEL 236 DIGITAL FREQUENCY TO VOLTAGE CONVERTER
Features
- Fast response
- High accuracy
- Delta-T (period deviation) mode
Description
The Model 236 digital frequency to voltage converter can be jumper-selected at one of two fullscale frequencies, and will operate down to 0.25% of full scale. Standard ranges are 3kHz and 25kHz, with others available on request. Another internal jumper selects between normal F/V operation and Delta-T operation, where the output indicates cycle-by-cycle deviation from average period.
Specifications
| Input: | 0.025V peak to 100V peak |
| Common mode rejection: | 2.5VRMS DC to 1kHz will not trigger the unit |
| Input comparator: | Automatic adjustment of threshold, optimized for variable reluctance pickups |
| Frequency ranges: | Internal jumper selects one of two fullscale ranges: 25kHz or version-specific lower range (1kHz, 1.5kHz, 3kHz, 10kHz) |
| Low-input cutoff: | Input signal frequency below 0.25% fullscale will cause outputs to go to zero and a no-input indication to light |
| Analog output: | Version-specified 0-5VDC or 0-10VDC fullscale output, with front panel trimpots to adjust span and zero |
| Output accuracy: | ±0.05% of fullscale reading |
| Transient response: | 2/f (two periods of input signal) max. |
| Output noise: | 5mVRMS max., DC to 100kHz |
| Mechanical: | DIN rail mount plastic enclosure, 2.9″ x 3.1″ x 0.9″ |
