High Resistance Box
75/120 Oumu High Resistance Box
| Overview | |
the High Resistance Box is a kind of hardware access device specially designed for signaling acquisition application. The product realizes the function of high resistance separation and wiring transfer by means of high resistance bonding. High Resistance Box products are divided into two types, 120 ohm high resistance junction box (RJ48 joint 120 ohm access) and 75 ohm high resistance junction box (CC4 joint 75 ohm access). Their connection interfaces are DB68 and RJ48. The 120 ohm High Resistance Box can be configured with a dial-code switch to: 1）120 ohm high resistance mode； 2）Through mode, compatible with existing 120 ohm wiring panel. 75 ohm high resistance junction box can be configured with a dial-code switch to： 1）High barrier + impedance conversion, 75 ohm access, 120 ohm output； 2）Does not weld high barrier isolator and impedance conversion, through mode compatible with existing 75 ohm wiring panel； 3）可Do not weld high barrier, use as 75-120 ohm impedance converter. |

| Features & Benefits | |
| High Stability |
All the components of the hardware part of the product adopt surface mount technology, PCB board adopts multi-layer board design, with high EMI\EMC, the product is stable and reliable. |
| High applicability |
Since almost all the product sets the application scenarios of 75/120ohm wiring panel functions, this product can almost meet the application of the original wiring panel and has high practicality. |
| Flexible & Easy Expand |
The High Resistance Box is equipped with flexible dialing switch, which can be configured into 8 working modes with high flexibility through dialing configuration， |
| Simplicity |
Because the high-resistance junction box has built-in high-resistance function, it does not need to have external high-resistance module, which avoids the messy wiring site. Therefore, this product has certain simplicity for construction. |
