1734-IB8S 具有安全仪表级别 要求的应用 安全模块

【产品详情】

1734-IB8S 是 Allen-Bradley 制造的模块，用于具有安全仪表级别 （SIL） 要求的应用。该模块是 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，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。它具有一个具有双通道模式功能的通道，用于评估两 （2） 个输入信号的一致性，使该模块可用于安全类别 3 和 4 的应用。

1734-IB8S 也可在单通道模式下使用。此模式评估单个信号，然后允许该模块用于安全类别 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连接时启用该检查。该安全模块的每个通道都具有可单独调节的ON和OFF信号延迟，用于防止信号波动引起的假阳性和假阴性读数。

1734-IB8S 的最大散热为 11.62 BTU/小时，重量为 62.4 克或 2.2 盎司。它的标称输入电压为 24 V DC，最大输入电流为 175 mA，最大功耗为 3.4 W。1734-IB8S 可与 SmartGuard、GuardLogix 和 Compact GuardLogix 控制器配合使用，并在 POINT I/O 平台中用于管理 CIP 安全协议扩展。1734-IB8S 的工作电压为 19.2 至 28.8 伏直流电。它还具有 25 mA 的最大电源总线电流（空载）和 50 V 的连续隔离电压。

1734-IB8S 尺寸为 77 x 25 x 55 毫米或 3.03 x 0.98 x 2.17 英寸，每个模块有 8 个输入和吸电流输入类型，每个通道的反应时间为 16.2 毫秒。1734-IB8S 模块有 A 系列和 B 系列。它具有开放式外壳类型，可以水平或垂直安装。1734-IB8S 可以通过 1734-AENT、1734-AENTR 或 1734-PDN 网络适配器通过以太网/IP 和 DeviceNet 网络进行通信。

【英文介绍】

The 1734-IB8S is an Allen-Bradley manufactured module for applications with safety instrumentation level (SIL) requirements. The module is a POINT Guard IO security module with eight (8) current absorption input channels and four (4) pulse current source pulse test outputs.

The module is typically used for applications that perform safety applications, such as emergency stop buttons, door switches, light curtains, and other safety devices that may be connected to the module. It features a channel with a dual channel mode capability for evaluating the consistency of two (2) input signals, making the module usable for applications in security categories 3 and 4.

The 1734-IB8S can also be used in single channel mode. This mode evaluates a single signal and then allows the module to be used for security category 2 applications.

It has a configurable difference time that determines the acceptable difference time between 2 channels before the module declares a fault. It also has an external wiring short circuit check function, which is enabled when the input channel is connected to the test output. Each channel of the safety module has individually adjustable ON and OFF signal delays to prevent false positive and false negative readings caused by signal fluctuations.

The 1734-IB8S has a maximum heat dissipation of 11.62 BTU/ hour and a weight of 62.4 grams or 2.2 ounces. It has a nominal input voltage of 24 V DC, a maximum input current of 175 mA, and a maximum power consumption of 3.4 W. The 1734-IB8S works with SmartGuard, GuardLogix, and Compact GuardLogix controllers and is used to manage CIP security protocol extensions in POINT I/O platforms. The 1734-IB8S operates at 19.2 to 28.8 volts DC. It also has a maximum power bus current of 25 mA (no load) and a continuous isolation voltage of 50 V.

Measuring 77 x 25 x 55 mm or 3.03 x 0.98 x 2.17 inches, the 1734-IB8S has eight inputs and current-drawing input types per module, with a response time of 16.2 milliseconds per channel. The 1734-IB8S module is available in series A and Series B. It has an open housing type and can be mounted horizontally or vertically. The 1734-IB8S can communicate over Ethernet /IP and DeviceNet networks via a 1734-AENT, 1734-AENTR, or 1734-PDN network adapter.
