Product Information

Full details

This Eaton Moeller series EASY I/O expansion module is designed for users of the easyE4 system seeking to extend its input/output capabilities. Its key benefit is providing 4 digital inputs and 4 relay outputs, along with expandability, to enhance control system functionality. A potential caveat is its specific compatibility with the easyE4 system and a voltage supply requirement of 12-24 V DC or 24 V AC.

Extended Product Information

FAQs

What is the maximum switching current for the relay outputs?

The maximum switching current for each relay output is 5A.

What type of power supply does this module require?

The module requires a supply voltage of 12-24 V DC or 24 V AC, with a ripple not exceeding 5%.

Can this module be used with systems other than Eaton easyE4?

No, this module is specifically designed as an expansion device for the Eaton easyE4 system.

What is the IP rating of this module?

The module has an IP20 rating, meaning it is protected against solid objects greater than 12.5 mm but offers no protection against water.

How many digital inputs and outputs does this module have?

This module provides 4 digital inputs and 4 digital outputs (relay type).

What are the dimensions of the module?

The module measures 90 mm in height, 35.5 mm in width, and 58 mm in length.

What mounting options are available?

The module can be mounted on a 35 mm DIN rail (IEC/EN 60715) or via screw mounting using optional brackets (ZB4-101-GF1).

Troubleshooting

Module not recognized by easyE4 system.

Verify the module is correctly seated and all interface connections to the easyE4 are secure. Check that the easyE4 system firmware is up to date and supports this expansion module.

Relay outputs not switching.

Confirm the output is being triggered by the easyE4 logic. Check the wiring to the load and ensure the load does not exceed the 5A switching current limit. Verify the relay contacts are not physically damaged.

Digital inputs not registering signals.

Ensure the input signal voltage is within the 12-24 V DC or 24 V AC range. Check the wiring to the input terminals and verify the signal source is functioning correctly. Confirm the input is not set to a non-active state in the programming.

Module overheating.

Ensure the module is installed with adequate ventilation and is not exceeding the maximum ambient temperature of +55 °C. Check for any short circuits or excessive loads on the outputs.

Pros and Cons

Pros

  • Expands the I/O capacity of the easyE4 system.
  • Reliable relay outputs with significant breaking capacity.
  • Flexible DC and AC voltage input options.
  • Robust against common industrial electrical disturbances.
  • Compact form factor for easy integration into control panels.
  • Expandable, allowing for future system growth.

Cons

  • Exclusively compatible with the Eaton easyE4 system.
  • Limited to 4 digital inputs and 4 digital outputs.
  • Requires a specific voltage supply range (12-24V DC / 24V AC).
  • IP20 rating may not be sufficient for highly dusty or wet environments.
  • No analog input or output capabilities on this module.

Setup, Compatibility & Care

Setup:

  1. Ensure the power supply meets the module's requirements (12-24 V DC or 24 V AC, with ripple not exceeding 5%).
  2. Mount the module onto a 35 mm DIN rail (IEC/EN 60715) or use optional mounting brackets.
  3. Connect the module to the easyE4 system using the appropriate interface.
  4. Wire the digital inputs and relay outputs according to your control logic diagram, ensuring secure connections with the 6.5 mm screw terminals.

Compatibility:

  • Primary System: Exclusively designed for use with the Eaton easyE4 control system.
  • Mounting: Compatible with 35 mm DIN rail mounting.

Care:

  • Cleaning: Wipe the exterior of the module with a dry or slightly damp cloth. Avoid using solvents or abrasive cleaners.
  • Environment: Operate within the specified ambient temperature range of -25 °C to +55 °C and air pressure range of 795 to 1080 hPa.
  • Maintenance: Periodically check wiring connections for security. Ensure adequate ventilation around the module.
