It measures 13.5 x 19 x 8.5 inches and has a weight of 8.7kgs. The 1771-A3B is intended for use in an industrial setting which has a relative humidity level of between 5 and 95% without condensation.

The 1771 I/O modules to be mounted on the 1771-A3B chassis do not have to be disconnected when removing the modules because they have remote termination panels and wiring arms.
