The module is used for galvanically isolated intrinsically safe connection of devices and sensors with a discrete output of the “dry contact” type, as well as data reception from instruments with a pulse (frequency) output.
The module is used for galvanically isolated intrinsically safe connection of devices and sensors with a discrete output of the “dry contact” type, as well as data reception from instruments with a pulse (frequency) output.
The input’s operation mode is configured as needed. Two modes are provided:
| Module configuration | Number of inputs | Galvanic isolation of inputs |
| MRD-4 | 4 | no |
| MRD-8 | 8 | no |
| MRD-4 with galvanic isolation | 4 | yes |
| MRD-8 with galvanic isolation | 8 | yes |
The module is used for a galvanically isolated spark-proof connection of devices and sensors with analogue outputs of the following types:
The analogue-to-digital converter provides measurement of input quantities with the standard accuracy of ± 1%, or with increased accuracy of ±0.2%.
| Module configuration | Accuracy | Number of inputs | Galvanic isolation of inputs |
| MRA-2 | ±1% | 2 | no |
| MRA-4 | ±1% | 4 | no |
| MRA-2 with galvanic isolation | ±1% | 2 | yes |
| MRA-4 with galvanic isolation | ±1% | 4 | yes |
| MRA-2 increased acc. | ±0.2% | 2 | no |
| MRA-4 increased acc. | ±0.2% | 4 | no |
| MRA-2 increased acc., with galv. isolation | ±0.2% | 2 | yes |
| MRA-4 increased acc., with galv. isolation | ±0.2% | 4 | yes |
