What type of input signals does the 1756-IG16 module accept?
The 1756-IG16 is a Digital DC Input Module designed for Transistor-Transistor Logic (TTL) level devices. It accepts 5 Volts DC TTL source inputs, with an operating voltage range of 4.5 to 5.5 Volts DC.
How many input points does the 1756-IG16 provide, and how are they configured?
The module provides 16 input points, configured as 9 points per common. It features removable terminal blocks for easy field wiring and maintenance.
What is the input delay time for the 1756-IG16?
The input delay time is 0.25 milliseconds plus the user-selected filter time. The hardware delay varies by transition: for 'off' to 'on' (5 to 0 V DC), the nominal delay is 270 microseconds (max 450 microseconds); for 'on' to 'off' (0 to 5 V DC), the nominal delay is 390 microseconds (max 700 microseconds).
Which removable terminal blocks are compatible with the 1756-IG16?
The 1756-IG16 is compatible with the 1756-TBNH and 1756-TBSH removable terminal block housings.
What software version is required to configure the 1756-IG16?
RSLogix 5000 software version 8.02.00 or later is required for setup and configuration of the 1756-IG16 module.
What are the power consumption specifications for the 1756-IG16?
The module has a maximum power dissipation of 1.4 Watts at 60 degrees Celsius. The backplane current draw is 110 milliamps at 5 Volts DC and 2 milliamps at 24 Volts DC, with a backplane power consumption of 0.61 Watts.
How does the TTL input logic work on the 1756-IG16?
TTL inputs on the 1756-IG16 are inverted, meaning low-true format is used. An input voltage between 0.2 and 0.8 Volts is guaranteed to be in the 'True' or 'On' state. Voltages between 0.8 and 2.0 Volts are not guaranteed, while voltages between 2.0 and 5.5 Volts are guaranteed to be in the 'Off' state.
Does the Allen-Bradley 1756-IG16 come with a warranty?
Yes. The 1756-IG16 is backed by our 24-Month Replace Industrial Warranty, with no rush fees or hidden warranty charges. If a unit fails under normal use within the warranty period, we repair or replace it.
