1756-IB32 Description

The 1756-IB32 is a digital I/O module. Part of the system, this input module has 

32 inputs available in 2 groups, with 16 points in each group. It is mounted to a 

chassis by using the required removable terminal block housing, or RTB, such as 

either the 1756-TBCH or 1756-TBS6H. This module, occupies a single slot of the 

Chassis and supplied with an open enclosure type. The 1756-IB32 module has an 

operating voltage range of 10 to 31.2 Volts DC and a nominal input voltage of 24 

Volts DC. It has a voltage category of 12/24 Volts DC sink, a current draw of 120 

mA at 5.1 Volts and 2 mA at 24 Volts, and a total backplane power rating of 0.66 W. 

The maximum power dissipation is 6.2 W at 60 degrees Celsius, while the 

thermal dissipation is 21.1 BTU/hour, also at 60 degrees Celsius. The 1756-IB32 

digital I/O module also has a maximum inrush current rating of 250 mA, which 

decays to less than 37% in 22 milliseconds without activation. In an off-state, its 

maximum current is 2.27 mA and its maximum voltage is 5 Volts. The input delay 

time for the off-to-on and on-to-off processes differ. For the off-to-on process, 

there is a hardware delay of up to 380 microseconds plus a user-configurable filter 

time of either 0, 1, or 2 milliseconds. The on-to-off delay time includes the hardware 

delay time of up to 420 microseconds plus the user-configurable filter time of either 

0, 1, 2, 9, or 18 milliseconds.

The 1756-IB32 is a High-Density Discrete input module that belongs to the product 

family of Programmable  Controllers (PAC). This module features Thirty-Two (32) 

input channels, grouped in Two (2) with Sixteen (16) channels each group.

It may be installed to a local I/O rack or distributed I/O chassis or in a stand-alone 

or Distributed Control Systems (DCS) such as Plant PAx. One this module is entered 

through the Hardware configuration, the module’s parameters are accessible such as 

the module’s general properties with important parameters of compatible keying and 

slot assignment. This module also has a configurable Request Packet Interval (RPI), 

Module Inhibition, Reaction to communication failure and Scheduled connection 

over ControlNet. Each channel of this module has configurable filter settings to 

allow fine tuning of the module’s reaction time to signals. This adjustment is 

useful in applications where discrete signals are erratic and exposed to noise. This 

feature helps prevent false positive negative readings.

This module is also provided with the capability of self-diagnosis through the module 

info where the module’s diagnostic status can be monitored such as minor and major 

fault. It can also detect the status of the backplane where the module is connected.

This module is shipped with a Removable Terminal Block (RTB). This RTB enables 

modular replacement of a defective module an provides ease of wiring the 

signals. Compatible RTB for this module are 1756-TBCH 1756-TBS6H or a 

36-terminal RTB.
