05701-A-0325 通讯模块Honeywell 控制脉冲

制造商:霍尼韦尔

产品编号:05701-A-0325

产品类型:DC输入卡

机架的直流电可以通过dc输入卡进入子机架。该电源可由用户从外部标称24V直流电源提供。直流电源通过工程卡和子机架背板连接到机架中的所有卡，并由dc输入卡上的保险丝保护。有-个由两部分组成的端子板TB1,有助于在不断开每根连接导线的情况下移除卡。

为为防止在使用八个以上5704催化卡的安装中沿机架背板出现过大电流，建议控制卡通过其相关的四继电器接口卡和仅用于为工程卡供电的DC输入卡供电。

如果需要，备用电池电源也可以连接到辅助直流输入连接。

PSU和辅助连接通过二_极管相互隔离。

●DC输入卡还提供RFI过滤和反极性保护。

Product type :DC input card

The direct current of the rack can enter the sub-rack through the dc input card. The power supply can be supplied by the user from an external nominal 24V DC power supply. The dc power supply is connected to all cards in the rack via the engineering card and subrack backplane, and is protected by a fuse on the DC input card. There is a two-part terminal board TB1, which helps to remove the card while constantly opening each connecting wire.

To prevent excessive current along the rack backplane in installations using more than eight 5704 catalytic cards, it is recommended that the control card be powered through its associated four-relay interface card and the DC input card used to power the engineering card only.

Backup battery power can also be connected to a secondary DC input connection if required.

The PSU and the auxiliary connection are isolated from each other by two polar tubes.

● The DC input card also provides RFI filtering and reverse polarity protection.
