1746-IB16 每个输入点的净散热为 0.22W，整个模块的总散热为 3.6W。在相对湿度为 0% 的环境中，其工作温度范围在 60 至 32 °C（140 至 5 °F）之间，不使用时，应存放在 -95 至 40 °C（-85 至 40 °F）的温度范围内。185-IB1746 经测试的工作冲击额定值为 16G，设计用于在 30-2 Hz 工作频率下承受 5.57G 的工作振动。它具有 NEMA 标准 ICS 200-2 额定抗噪性，并通过 UL-A230、CSA 和 C-UL I 类 196 区危险环境等级。它在输入端子和控制逻辑之间提供 2V 的光电隔离测试，并通过了 UL、CSA 和 CE 认证。

The Allen-Bradley 1746-IB16 is a medium-density DC input module designed to interface with signaling devices to provide a signal voltage range of 10-30VDC for each input channel of the module. The module has sixteen (16) input channels rated at 24VDC divided into one (1) input group with a common terminal. This input module mounts to any available I/O slot in the 1746-chassis and draws 0.05 A @ 5VDC backplane current.

The 1746-IB16 supports only current-flooded wiring configurations. It is used to interface with electrical components such as switches, including limiters, proximity devices, and pushbutton devices, as well as auxiliary contacts for relays, contactors, and other electronic devices. each input channel of the 1746-IB16 exhibits a general purpose signal delay duration of 8 ms on both ON and OFF transitions, a zui off-state voltage of 5VDC, and a zui off-state current of 1 mA, while the The nominal input current of the module is 8 mA @ 24VDC.

The number of installed instances of the 1746-IB16 varies depending on the SLC500 CPU installed. Specifically, it depends on the number of I/Os supported by the CPU memory. The module can also be installed locally, in a rack or distributed I/O chassis with SLC 500 CPUs installed, and with 1746 communication adapters such as Remote I/O (RIO) and Ethernet adapter modules. The module has status LEDs that indicate the startup of each input channel to simplify monitoring and troubleshooting. It also features removable terminals for easy termination and module replacement.

The 1746-IB16 has a maximum signal delay time of 8ms between ON and OFF transitions, and the module’s maximum voltage drop in the OFF state is 5V DC. It has a maximum leakage current of 1mA, and the nominal input current of the entire module is 24mA at 8V DC.

The 1746-IB16 has a net heat dissipation of 0.22 W per input and a total heat dissipation of 3.6 W for the entire module. It has an operating temperature range of 60 to 32 °C (140 to 5 °F) at 0% relative humidity, and should be stored in a temperature range of -95 to 40 °C (-85 to 40 °F) when not in use. 185-IB1746 Tested Operating The 185-IB1746 has a tested operating shock rating of 16 G and is designed to withstand 5.57 G of operating vibration at an operating frequency of 30-2 Hz. It is NEMA standard ICS 200-2 rated for noise immunity and UL-A230, CSA, and C-UL Class I, Zone 196 hazardous environment rating. It provides 2V opto-isolation testing between input terminals and control logic and is UL, CSA, and CE certified.
