Schneider 140ERT85410IAT SOE Module

The 140ERT85410IAT records sequence of events for Schneider Quantum PLC systems. This module time-stamps digital input changes with microsecond accuracy. Its rectangular frame measures 166 millimeters in width. The module height reaches 140 millimeters exactly. Depth stays at 115 millimeters. You will find this unit weighs approximately 0.68 kilograms. Therefore, installation requires sliding the unit into a standard Quantum rack slot. One 20-pin removable terminal block handles all field wiring connections.

Physical Layout and Connectors

The terminal block accepts wires up to 16 AWG gauge. A green LED indicates power present on the module. Individual LEDs show status for each input channel. Two rotary switches allow manual address selection for the module. Four mounting screws secure the unit firmly in the rack.
