TCU Contactor
The module, called TCU-.-V5 forms together with the display and relay module type DISGRACO
or PDIM-2D-… (with Software Version ≥3.56) a functional unit.
The contactor module is a compact unit with integrated control and monitoring electronics. The
integrated control and monitoring electronics, called MPE-2D-V5 (Module de Protection
Electronique 2 Départs Version 5), are also termed protection module.
No parameterisation or adjustments are made on the contactor modules as such. These
adjustments are made on the associated relay modules type DIS-2D, or DIS-GRACO in the
intrinsically safe terminal compartment.
