It converts AC signals provided by user devices to the logic level needed by the processor. The Allen-Bradley 1771-IA is a PLC 5 Digital AC/DC Input Module. The individual channel’s On-state voltage range is 87VAC to 138VAC 97VDC to 138VDC. It has backplane current draw of 75 mA, Power Dissipation of maximum 10.7 Watts and maximum Thermal Dissipation of 36.5 BTU/Hr. It can be installed to any available slot with consideration to the power supply capacity. This module occupies a single slot of the 1771 PLC5 chassis. After configuration, the corresponding entry within the binary file is automatically created. To use this input module, it must be configured first using via the channel configuration. This wiring arm may be directly connected to the replacement module.īinary files are data file types intended for discrete devices. In the event when the 1771-IA needs replacement, the wiring arm may be disconnected to preserve the existing wiring. Wiring arms provide a modular means of terminating signal wire to the module which also contributes to the modularity if the system. This input module is provided with a wiring arm with part number 1771-WA. Field instruments such as Limit switches, auxiliary contacts, sensors and other devices. This module features an embedded Eight (8) discrete input channels operating at 120VAC and 125VDC voltage category.ĭiscrete input modules provide interface to field instruments to monitor and evaluate their state. This electronic hardware belongs to the legacy PLC5 product family of Allen-Bradley. The 1771-IA is a Programmable Logic Controller (PLC) input component.
