1734-IB8S Allen-Bradley制造的模块 用于有安全仪表等级

1734-IB8S是Allen-Bradley制造的模块，用于有安全仪表等级(SIL)要求的应用中。该模块是一个POINT Guard IO安全模块，具有八(8)个电流吸收输入通道和四(4)个脉冲电流源脉冲测试输出。该模块通常用于执行安全应用的应用中，例如紧急停止按钮、门开关、光幕和其他可能连接到该模块的安全设备。

它具有双通道模式能力的通道，用于评估两(2)个输入信号的一致性，这使得该模块可用于安全类别3和4的应用中。1734-IB8S也可用于单通道模式。该模式评估单个信号，然后允许模块用于安全类别2的应用。它有一个可配置的差异时间，用于确定在模块声明故障之前2个通道之间可接受的差异时间。

它还具有外部接线短路检查功能，当输入通道与测试输出相连时，该功能使能。该安全模块的每个通道都有单独可调的开和关信号延迟，用于防止信号波动引起的假阳性和假阴性读数。该模块可使用Studio 5000编程软件V21、RSLogix 5000编程软件V17和RSNetworx for DeviceNet版本9进行配置。对于RSLogix 5000，如果模块与模拟Point Guard IO模块一起使用，则附加配置文件必须更新到版本2.02.004或更高版本。

Allen-Bradley 1734-CTM POINT I/O Universal terminal module extends the terminal functions of POINT I/O. It is part of the Bulletin 1734 series of POINT I/O modules. Mount it on the 1734-TOP, 1734-TOPS, 1734-TB, or 1734-TBS terminal base assembly. Before installing the module, ensure that the mounting base is properly keyed.

The 1734-CTM supports 8-channel high-density modules and enables the management of field devices connected to POINT I/O solutions. It can also be used as an external connection in common connections of three-wire devices.

The 1734-CTM universal terminal module has 5 key switch positions and is tested for 60 seconds isolation voltage (continuous voltage tolerance rating) at 1600 Vrms. It has 10 to 28.8 volts of direct current or 120 to 240 volts of AC supply voltage. It has no shell. The 1734-CTM is C-UL-US certified and UL certified for use in Class I, Zone 2, Group A, B, C and D hazardous sites. Operating temperatures should be in the range of -20 to 55 degrees Celsius (-4 to 131 degrees Fahrenheit), relative humidity between 5% and 95%, and non-condensing for best performance.
