IC695AIG704
IC695AIG704 The ModuleBus Modem has an electrical and an optical Modulebus interface which are logically the same bus. A maximum of 12 I/O modules can be connected to the electrical ModuleBus and up to seven clusters can be connected to the fiber optic ModuleBus.
The fiber optic interface is intended for local distribution of I/O clusters and where more than 12 I/O modules are required in an I/O station.

The Hydran M2 is a compact permanently mounted on-line transformer monitoring device that will
personnel to developing fault conditions. It continuously monitors a composite value of various fault gases (in ppm) or a Hydrogen gas only value (depending on sensor purchased). In addition it tracks moisture in oil (reading in %RH and ppm).
With additional sensors added, the Hydran M2 can also compute transformer mathematical models d on IEEE® and IEC® standards to provide further information on the performance of the transformer.Hydran M2是一种紧凑的*安装在线变压器监测装置，可提醒人员出现故障情况。它连续监测各种故障气体的合成值（ppm）或仅氢气值（取决于购买的传感器）。此外，它还跟踪油中的水分（读数为%RH和ppm）。
添加了额外的传感器后，Hydran M2还可以根据IEEE®和IEC®标准计算变压器数学模型，以提供关于变压器性能的进一步信息。Real-time Hydrogen or composite fault gas monitoring system
