5SHY3545L0010 3BHB013088R0001从传感器连接到I/O模块

信号流从传感器连接到I/O模块上的接线板开始。这个

接线板安装在机柜上，有两种基本类型：T型和

S型模块。

T型模块通常将输入扇风至三个独立的I/O包。它们包含两个

可拆卸的24点屏障式接线板。每个点可以接受两个3.0 mm2

（#12，AWG）电线，每点300 V绝缘，扁平或环形接线片。俘虏

还提供了用于端接裸电线的夹具。螺钉间距为9.53毫米（0.375英寸）

最小，中心到中心。T型模块通常是表面安装的，但也可能

采用DIN导轨安装。

每个块旁边都有一个屏蔽带，实际上是

安装模块的金属底座。宽模块和窄模块排列在

Signal flow begins with a sensor connected to a terminal block on an I/O module. The terminal board mounts to the cabinet and is available in two basic types: T-type and S-type modules. T-type modules typically fan the inputs to three separate I/O packs. They contain two removable 24-point, barrier-type terminal blocks. Each point can accept two 3.0 mm2 (#12,AWG) wires with 300 V insulation per point and spade or ring-type lugs. Captive clamps are also provided for terminating bare wires. Screw spacing is 9.53 mm (0.375 in) minimum, center-to-center. T-type modules are normally surface mounted, but may also be DIN-rail mounted. A shield strip is provided next to each block, which is actually the left-hand side of the metal base where the module is mounted. Wide and narrow modules are arranged in vertical columns of high and low-level wiring that can be accessed from top and/or bottom cable entrances. An example of a wide module is a module containing magnetic relays with fused circuits for solenoid drivers.
