Removable screw connectors for the M168 EEV module
The Schneider Electric TM168SCTBEVCM is a removable screw terminal block accessory for the Modicon M168 logic controller, specifically the electronic expansion valve module in the M168 HVAC controller line. It is sold singly as a connection accessory rather than as part of the controller body. Functionally this part carries the field wiring from the EEV driver to the electronic expansion valve on the refrigeration circuit, which is the only load a screw terminal block of this class will see in the M168 architecture.
Lifecycle read: eol_hot and what that means for the BOM
The product is listed with lifecycle stage eol_hot and overall status Obsolete, so the manufacturer has stopped accepting new orders for the part number itself. For a contract build, that means any reference design calling out this terminal block needs an engineering change request before a customer AVL re-approves a substitute. Quantity, condition, and traceability are confirmed per RFQ rather than from a stocked catalog line.
Form-factor and panel-side handling
The terminal block is specified as removable — it unplugs from the EEV module body for wiring bench-side and snaps back in at commissioning. For a panel wireman that saves pulling the controller off the DIN rail when re-terminating a refrigerant solenoid lead or replacing a damaged screw. Screw termination suits the typical EEV field wiring gauge where a push-in or spring-cage would not seat reliably; one block per package means each EEV driver needs its own order line on the BOM.
