Controller/terminal compatibility
All RES-408 RESISTRON temperature controllers manufactured as of June 2006 are supplied as an upgraded
version.
Among other things, the data transfer between the controller and the terminal has been modified. These changes
were necessitated by the new European RoHS/WEEE Directives. Lead has now been banned from some of the
electronic components used in our products.
As a result, all RES-408 controllers manufactured up to May 2006 can only be operated with a T-400
terminal. Controllers manufactured as of June 2006 can only be operated with a T-408-1. Malfunc-
tions or damage may otherwise occur.
This has no effect on temperature control or on the external PLC control signals.
RES-408 controllers manufactured as of June 2006 are fully electrically compatible with the old ver-
sion (as far as the PLC control signals are concerned).

Installation
If several controllers are installed on one top hat rail
(DIN TS35 rail), a clearance of at least 20mm should
be allowed between them.
The moving clip required for fastening must be facing
down for mounting on a horizontal top hat rail.
End holders to mechanically fix the controller must be fitted at both ends for
mounting on a vertical top hat rail.
Weight
Controller:
Approx. 0.7kg (incl. connector plug-in parts)
Terminal:
Approx. 0.15kg
Housing material
Controller:
Plastic, polycarbonate, UL-94-V0
Terminal:
Black plastic, type Noryl SE1 GFN2

If ferrules are used, they must be crimped in accordance
with DIN 46228 and IEC/EN 60947-1.
This is essential for proper electrical contact in the terminals.
