Product Overview
The Allen-Bradley 1756-IA16I is a ControlLogix Analog I/O Module with 16 inputs. It is compatible with the ControlLogix PLC systems. The 1756-IA16I has 16 individually isolated inputs that belong to 120 Volts AC, 50 to 60 Hertz power category. The user-selectable filter time ranges from 0 to 18 milliseconds. This ControlLogix Bulletin 1756 device multicasts fault and status data to any PLC controller. It accomplishes this over a module-fault word. The Allen-Bradley 1756-IA16I analog I/O module has a 32-bit module-fault word. Note that this is a 16 I/O module and only the first 16 bits are used in the module-fault word. The 1756-IA16I returns to the PLC only the general fault and input data.

Description
The Allen-Bradley 1756-IA16 is a ControlLogix I/O Module. This AC digital input module is an isolated type and has a display that shows the input and communication status and module health. The module's input channels are individually isolated which are also individually rated at 125 Volts continuous input. This module directly connects to a ControlLogix chassis. Removable terminal block housings compatible with this module are the 1756-TBCH and the 1756-TBS6H.
The input voltage and voltage category of this module are both 120 Volts AC. The current draw at 24 Volts is 3 milliamps and for 5.1 Volts, it is 125 milliamps. The module's operating voltage ranges from 79 to 132 Volts AC and 47 to 63 Hertz. Maximum power dissipation is 4.9 Watts at 60 Degrees Celsius and the thermal dissipation is 16.71 BTU per hour. Inrush current, at a maximum, is 250 milliamps and the total backplane power is 0.71 Watts. The screw to backplane input delay times are as follows: hardware delay is 10 milliseconds maximum plus user-selectable filter time (1 or 2 milliseconds), and hardware delay has a maximum time of 8 milliseconds and a user-selectable filter time ranging from 9 to 18 milliseconds. The maximum off-stage voltage is 20 Volts and 2.5 milliamps for the maximum current. For the on-state, the minimum is 5 milliamps at 79 Volts AC, ranging from 47 to 63 Hertz, while the maximum is 15 milliamps at 132 Volts AC, ranging as well from 47 to 63 Hertz.
The Allen-Bradley 1756-IA16I is a Sixteen (16) Channel Discrete AC input module that features individually isolated channels. This module operates at a nominal input voltage of 120VAC with frequency of 50/60 Hz.
Frequently asked questions
Q1: How are the 16 inputs grouped?
A: Inputs are divided into 8 pairs (channels 0–15) with shared common terminals. Each pair must share the same voltage source.
Q2: Can the module handle AC voltages?
A: No. The 1756-IA16I is designed for DC inputs only. For AC signals, use the 1756-IA16D AC input module.
Q3: How to troubleshoot a "Fault" LED on the module?
A: Check for wiring errors (e.g., reversed polarity), blown fuses, or field device failures. Use Studio 5000's "Module Diagnostics" tab for detailed error codes.
