Eaton Cutler-Hammer D100EA20 20 I/O Expander with 12 Inputs and 8 Outputs

The D100EA20, an expansion unit produced by the Cutler - Hammer brand, is a 20 I/O expansion module. It has been designed with a 30 - centimeter cable to operate under a 115 - Volt AC power supply. Additionally, this expansion module has been manufactured with 24 - Volt DC contacts, which are typically dry.

The D100EA20 was primarily engineered to supply extra outputs and inputs to the D100 PLC. The expansion unit is usually connected to the controller via cables. A controller can accommodate a maximum of two expansion units only on the condition that the combined total number of inputs and outputs of the controller and the expanders does not exceed the maximum I/O count specified for the controller.

The connection of an analog input module into the D100 controller usually doesn't affect the D100EA20 because the analog input module is generally connected before the D100EA20. This situation only arises when certain analog capabilities are needed in the controller's system.

The D100EA20 expansion cables should be kept separate from other cables, particularly power and input/output cables. Do not interweave the expansion cables with the power and input/output cables. Always replace the connector covers after inserting the D100EA20's cables. It should be noted that the module's expansion cables should not be disconnected or connected while the power is on. Before applying power, make all connections and examine them thoroughly. Remember to remove the power when disconnecting the expansion cables.
