Overview Manuals DC Outputs Load Matching Output Testing Applications

Features:

  • Twenty-four-volt outputs: drives documented 24 V DC field circuits.
  • Marked current rating: retains the 0.5 A module identity.
  • Load-specific control: accounts for polarity, induction and safe state.
The 8164 hardware is a DC output role and should not be confused with the adjacent 8163 input module.

Channel assignment, shared supply, load behavior and suppression remain part of the acceptance boundary.

A controlled commissioning plan proves de-energized state, commanded output and real field feedback one circuit at a time.

Description
8164-4002 is an Alstom/CEGELEC GEM 80 digital output module marked for 24 V DC field circuits and a 0.5 A output rating. Its channel assignments belong with the installed load and feedback map.

Selection of 8164-4002 must account for load polarity, steady and inrush current, inductive energy, shared supplies, suppression and safe state. The front-panel rating does not by itself approve every solenoid, relay coil, lamp or electronic input.

Before replacing 8164-4002, isolate the field supply and document every output and return. Reconnect one circuit at a time, prove de-energized and commanded states, and confirm field feedback and sequence behavior before automatic commands are restored.
Technical notes
8164-4002 is a 24 V DC output module marked 0.5 A, but inductive energy and inrush can exceed the steady load. Review polarity, shared supplies, suppression and safe state for every circuit; stop installation if the channel map or field-return arrangement differs from the controlled wiring record.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What must be reviewed before connecting a load to 8164-4002?
Review 24 V DC polarity, steady current, inrush, inductive energy, shared supply, suppression, terminal assignment and safe state.
Why is the 0.5 A marking insufficient to approve a load for 8164-4002?
A relay coil, lamp or solenoid can impose inrush or inductive stress that is not described by normal current alone.
When should receiving hold 8164-4002?
Hold it if the order reference, 24 V DC and 0.5 A markings, connector layout, board condition or dimensions differ from the installed record.
What should be recorded before removing 8164-4002?
Record every output terminal, load, field supply and return, protective device, suppression component, safe state and feedback point.
How should 8164-4002 be commissioned after wiring?
Keep the process secured, prove the de-energized state, command one output at a time and confirm its field response and feedback.
What releases 8164-4002 to automatic operation?
Every output must control only its documented load, return to its safe state and pass the complete approved machine or process sequence.
