1769-IF8 在 120 V DC 时的背板消耗电流为 5 mA，在 70 V DC 时为 24 mA，运行时可散发 3.64 W 的热量。它使用 Delta -Sigma 模数转换器，其分辨率为 16 位单极性或 15 位加号。它具有与滤波器/配置相关的通道响应速度。它在 120 V DC 时的zui大总线消耗电流为 5 mA，在 70 V DC 时为 24 mA，电压端的输入阻抗为 220 kg，电流端的输入阻抗为 250 Ω。
1769-IF8 的公共失调电压范围为每通道 +/-10 伏直流电，在 60 至 50 赫兹时的共模抑制比大于 60 dB。该模拟输入模块对电压信号和电流信号的总体精度分别为 +/-0.2% 和 0.35%，而电压和电流信号的总漂移精度分别为 +/-0.003%和每摄氏度 +/-0.0045%。它还具有 +/-0.03% 的输入非线性和 +/-0.03% 的可重复性。1769-IF8 有一个指示灯，显示模块的故障状态。1769-IF8 通过位报告对超量程或欠量程进行自动自诊断，还可以处理报警。它在 30.0 mA 电压端连续具有 +/-1 V DC 的zui大输入端过载，在 +/-32.7 V DC 处具有 +/-6 mA 的过载。其工作温度范围在 0 至 60 摄氏度（32 至 140 华氏度）之间，相对湿度限制为 95%，有冷凝。它重约 450 克（0.99 磅），尺寸约为 118 x 87 x 52.5 毫米。

1769-IF8 是由 Allen-Bradley 制造的紧凑型 I/O 模块，与 1769 CompactLogix 控制器和 MicroLogix 1500 控制器兼容。该控制器具有嵌入式八 （8） 个输入通道，支持差分和单端接线。
可配置信号为 0-20 mA 和 4-20mA 以及 +/10VDC、1-5VDC、0-5VDC、0-10VDC。

输入通道接收的模拟信号使用Delta-Sigma转换方法单独转换。转换后的信号存储在处理器的内存中，单极性为 16 位，双极性为 15 位。寄存器内有表示输入信号值的二进制位数组。为了正确显示等效的测量值或工程值，使用比例指令对数据进行调节。处理的数据可以配置为工程单位，根据 PID、百分比范围和原始数据进行缩放。

The Allen-Bradley 1756-RM is a ControlLogix redundant module. This module can only be used with the ControlLogix platform to enable controller redundancy. It manages the connection of two (2) identical controllers installed in the same rack with the same components and configuration. It provides redundant system monitoring and module health through embedded LED displays such as PRI, COM and OK. The 1756-RM has been released as Series A and Series B. The series is basically an enhanced version of the previous series, however, the 1756-RM with different series can coexist in a redundant configuration.

It is highly recommended to install the same series for maximum operability of redundant Settings. When used with the same series of redundant modules, the speed can reach 100 Mbps.

The 1756-RM is equipped with one (1) single-mode LC fiber optic connector. It requires the use of 1756-RMCx redundant cables to synchronize the operation of redundant controller pairs. This controller can be configured using the Redundancy Configuration tool to set redundancy and the Studio 5000 Logix Designer to configure the overall parameters of the module.

This module is compatible with 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17 ControlLogix chassis, 1756-PA72, 1756-PA75, 1756-PB72, 1756-PB75 standard power supplies and 1756-PA75R, 1756-PB75R, 1756-PSCA2 Redundant power supply. It is a single slot module that can be installed into any available slot in the case. The redundancy pair must have the same configuration as the partner chassis.

The 1756-RM has a current consumption of 2 mA at 4.1VDC, 5.1 mA at 1.2VDC, and 24 mA at 120VDC.

The 1756-RM redundancy module has a current consumption of 2 mA at 4.1 volts DC, 5.1 MA at 1.2 volts DC, and 24 MA at 120 volts DC. The device is installed in the case and can be installed in any slot. The 1756-RM module has a power consumption of 9 watts and a heat dissipation of 31 BTU per hour. The ControlLogix comes with an open housing and comes with a T4 temperature code. Regarding the physical characteristics of the module, it weighs about 0.29 kg or 0.64 LBS and is small in size. The 1756-RM module operates in a temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and can be stored in a temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The unit is manufactured according to a number of industry standards, including CE, CSA, Ex, C-Tick and c-UL-us standards.
