Detailed Product Description
AB 1771-IBN PLC5 Discrete Input Module Thirty-Two (32) InputChannels Technical Specifications for 1771-IBN
About 1771-IBNThe AB 1771-IBN is a 24VDC discrete input module from the bulletin
1771 product family. This module is a Programmable Logic Controller
(PLC) module that is used to interface external signaling devices
such as switches, sensors, auxiliary contacts that allow flow of
24VDC voltage or signal voltage with range of 10-30VDC. The 1771-IBN features Thirty-Two (32) input channels with nominal input range 4.7 mA @ 10VDC or 15.6 mA @ 30VDC. It has a minimum OFF-state Current of 1.7 mA @ 5VDC. Each channel of this module has an OFF-state voltage of 5VDC, maximum and ON-state voltage of 10VDC, minimum. The module’s input signal delay is 6 ms +/- 2 ms low to high and high to low propagation. It has a power dissipation of 16.4 Watts, maximum and Thermal Dissipation 53.3 BTU/Hr maximum and minimum of 5.1 BTU/hr minimum dissipation. This module has a backplane current draw of 280 mA at 5VDC, maximum. When terminating signal devices to this input module, appropriate wire size is 0.25-2.5 mm sq. (22...14 AWG) solid or stranded copper wire with insulation rating of 75 °C (167 °F) or greater and maximum insulation thickness of 1.2 mm (3/64 in.). It requires a field wiring arm with catalog number of 1771-WN with wiring arm screw Torque of 1.0 n-m. It has an open type enclosure. The 1771-IBN is configured using the RSLogix5 programming software which is the programming software for the entire PLC5 product family. The 1771-IBN consumes 32-Bit register which directly represent each channel of the module. Additionally, the 1771-IBN features Thirty-Two (32) LED indicators, dedicated for each of the input channels. It directly controls the state of corresponding bits in the PLC data table. It provides a modular design with space-saving means to add input to a PLC control system. It comes with a 1771-WN wiring arm to replace the module eliminating the need to disconnect the wiring. It is a series C module and supports 1/2 and 1-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 pushbuttons. The 1771-IBN module has 32 (4 sets of 8) inputs with a 10 - 60V DC Sink (Source load) voltage category. It has an operating voltage range of 10 - 30V DC. It has a typical signal delay of 6ms (+/-2) at On-DC state and 6ms (+/-2) at Off-DC state. It has a maximum Off-state current of 1.7mA and a backplane current load of 280mA. It has a maximum power dissipation of 15.6W and thermal dissipation of 53.3 BTU/hr. It is installed in a 1771 I/O chassis containing a PLC processor. Keying bands for putting it in the right slot are between pins 18 and 20 for the upper connector and pins 14 and 16 for the lower connector. The 1771-IBN module has 32 status indicators on 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.
