Allen-Bradley digital dc I/O modules interface to ON/OFF devices such as limit switches, pushbuttons, motor starters, pilot lights, and annunciators. These modules are compatible with all current Allen-Bradley programmable controllers. This saves on spare parts, system engineering, inventory, and training costs. .

Complementary I/O: An I/O technique that allows a PC to interface with an input and output module using the same location address in different I/O chassis. Complementary Module: A module that performs an opposite function; an input module complements an …

Our Bulletin 1794 FLEX™ I/O modules offer flexibility for your application with digital, analog, HART analog, and specialty I/O, with 4…32 points per module. You can mix and match digital and analog I/O with mounting and wiring options.

The 1771-N High Resolution Analog I/O modules are designed for use with 1771-RTPs (Remote Termination Panels) and connected by a 6 or 15 foot cable (Cat. No. 1771-NC6 or 1771-NC15). The conversion of the 1771-N Series I/O to a 1756 ControlLogix I/O can be accomplished without the removal of any field wires from the existing 1771-RTPs.

1771 digital ac input modules convert ac signals from user devices to the appropriate logic level for use within the processor. Typical input devices include: •proximity switches •limit switches •selector switches •float switches •pushbutton switches AC Input Modules

The Rockwell/1771-A2B 8-Slot I/O Chassis is designed for the 1771 series I/O modules. This chassis features back-panel mounting and 8 slots. The 1771-A2B is intended for use in a Pollution Degree 2 industrial environment, overvoltage Category II applications, and at altitudes up to 2000 meters without derating.

2019年7月2日 · We have been struggling for the last couple weeks with a recurring Remote I/O communication problem. The problem is described below. • PLC 5/40 channel 2A as the RIO scanner. • Four 1771-ASB modules for 1771 racks. • About fifteen 1794-ASB modules for Flex I/O racks (three recently converted from Block I/O). • One 1336-GM1 module for a 1336 drive.
