Overview Manuals Technical notes Product Applications Hardware Installation

Features:

  • Digital DC Input Module
  • Sixteen (16) Inputs
  • All 1771 I/O chassis except 1771-A1, -A2, and -A4
  • Between 10 and 12; Between 16 and 18
The Allen-Bradley 1771-IBD is a discrete input module from the 1771 product bulletin. It has Sixteen (16) 10-30VDC sink input channels with Minimum On-state Voltage 10VDC and Maximum Off-state Voltage of 5VDC. It is compatible for installation to all 1771 I/O chassis except 1771-A1, -A2 and A4.

Discrete input modules such as 1771-IBD are typically used to interface field signaling devices such as switches, sensors, auxiliary contacts that represent the state of the process. It is especially compatible for use with ON/OFF; 1 or 0 or binary operating devices.

The 1771-IBD comes with Eighteen (18) LED status indicators that provides information regarding the module status and the signal status present at each input channel of the module. It also comes with a Field Wiring Arm with compatible replacement part number of 1771-WH. Field Wiring Arms are used to provide modular wiring method as they can be removed from the module when terminating signals. Additionally, they contribute to ease of maintenance as they can be removed and installed to compatible modules without the need of disconnecting the attached wires.

The 1771-IBD Allen-Bradley Discrete input module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 1771-IBD comes with a 1771-WH wiring arm for ease of wiring and simplified replacing of the module in case of module malfunction, thus eliminating the need to disconnect the wiring first. It supports ½, 1, and 2-slot I/O addressing. It is compatible with source-switching devices such as dry-contact switches, electro-mechanical transmitters, and panel-switching devices like selector switches and pushbutton. The 1771-IBD module has 16 inputs with a 10 to 30 Volts DC Sink (Source load) voltage category. It has an operating voltage range of 10 to 30 Volts DC. It has a typical signal delay of 1.3 milliseconds (±0.1) at an on-DC state and 1.3 milliseconds (±0.1) at an off-DC state. It has a maximum off-state current of 2mA and a backplane current load of 130 mA. It has a maximum power dissipation of 6W and a thermal dissipation of 20.3 BTU/hour. It is installed in a 1771 I/O chassis containing a PLC processor. Keying bands for putting it in the right slot are found between pins 16 and 18 for the upper connector and between pins 10 and 12 for the lower connector. The 1771-IBD module has 1 green status indicator and 16 red status indicators for customer-side indication at the front panel. It contains optoelectrical isolation to protect the system circuits from electrical transients. It also contains an input filtering feature to reduce electrical noise.

Chassis Preparation: Power off the I/O chassis. Verify the module's keying; use plastic keying bands to ensure only the 1771-IBD can be inserted into the specific slot.
Module Insertion: Align the module with the card guides and slide it into the chassis. Apply firm, even pressure until it seats into the backplane.
Locking: Secure the module using the chassis latch or locking bar to prevent accidental disconnection during operation.
Wiring Arm: Attach the 1771-WH wiring arm to the pivot bar at the bottom of the chassis. This allows for module replacement without disconnecting field wiring. 

FAQs
