More Information

Overview Manuals Selection Installation Service Checks Applications

Features:

  • D-SERIES socket: the product is a relay socket for the Weidmüller D-SERIES.
  • Two changeover contacts: the socket is specified for two CO contacts.
  • Screw connection: the exact version uses screw connection rather than a PUSH IN connection.
FS 2CO ECO is the D-SERIES relay socket identified in Weidmüller ordering data as order number 7760056126.

Its two-changeover-contact arrangement provides the connection form identified for the matching relay-socket version.

The screw-connection version is a selection boundary: it should be matched to the required wiring method rather than substituted with a PUSH IN variant.

Apter Power supports documentation review, quotation and procurement for the Weidmuller FS 2CO ECO D-SERIES Relay Socket.

Description
FS 2CO ECO is a Weidmuller functional-safety relay module whose complete product identity should be retained with the control-panel documentation. The exact designation is important because safety-related relay hardware must be reviewed in its installed circuit context.

For a panel modification, FS 2CO ECO should be evaluated against the existing safety function and wiring documentation before it is selected. This keeps a maintenance request focused on the intended protective function instead of a generic relay replacement.

Using the full FS 2CO ECO designation in a sourcing enquiry helps separate the module from related Weidmuller control products. The equipment record should state the existing circuit role before any installation decision is made.
Alternative Names
FS2COECO FS2CO ECO FS-2CO-ECO FS 2 CO ECO 776005 6126
Technical notes
FS 2CO ECO is a functional-safety relay module, so its installed safety-circuit role is the governing boundary. A relay with a similar contact arrangement does not by itself demonstrate the same safety function. Stop a replacement decision until the panel safety documentation identifies the required function and wiring context.

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.
When a panel technician needs two change-over circuits, how should FS 2CO ECO be matched to the existing relay assembly?
Select FS 2CO ECO only when the panel schematic calls for a D-SERIES socket with two change-over contacts. A matching relay family name alone does not establish the required socket contact arrangement.
Can FS 2CO ECO be substituted with a four-contact D-SERIES socket during a repair?
No. FS 2CO ECO is a two-change-over-contact socket, while a four-contact version serves a different circuit arrangement. Keep the existing control drawing as the decision point before changing socket type.
For a failed relay interface, what should a maintenance engineer identify before ordering FS 2CO ECO?
Identify the installed relay, the socket’s terminal plan and the control-circuit function. FS 2CO ECO is a relay socket, so the complete relay-and-socket assembly must match the panel documentation.
How should FS 2CO ECO be handled during a screw-terminal wiring retrofit?
Use the approved terminal drawing to reconnect each conductor and inspect the completed screw-terminal connection before energising the circuit. Do not infer terminal functions from another D-SERIES socket with a different contact count or connection method.
When should an engineer stop a FS 2CO ECO replacement decision?
Stop if the existing relay type, two-contact circuit role or terminal wiring cannot be identified. Proceeding without those details can direct a repair toward a socket that does not match the installed control circuit.
What information should procurement retain for an FS 2CO ECO enquiry?
Retain the exact type FS 2CO ECO and order number 7760056126, together with the installed relay reference and required quantity. The manufacturer lists local availability restrictions, so the exact order number also helps avoid a regional catalogue mismatch.
