Modifications (MODs)
Owing to its universal design, the RESISTRON
temperature controller RES-407 is suitable for a very
wide range of heatsealing applications.
Various modifications (MODs) are offered for the
RESISTRON temperature controller RES-407 for
implementing special applications.
The modifications described here are just a few of the
large number available. Separate documents are
supplied for all modifications.
MOD 01
Amplifier for low secondary voltages
(U
R
= 0.25…16VAC). This modification is necessary,
for example, for very short or low-resistance
heatsealing bands.
Set point potentiometer PD-x
Front panel-mounting version for setting the required SET heatsealing temperature
of the RESISTRON temperature controller. The number which appears on the
display corresponds to the SET heatsealing temperature in °C.
Line filter
Essential in order to ensure CE conformity.
Optimized for the RESISTRON temperature controller.
Impulse transformer
Designed according to VDE 0570/EN 61558 with a one-section bobbin.
Optimized for impulse operation with RESISTRON temperature controllers.
Specified according to the heatsealing application
(
ª
ROPEX Application Report).
Communication interface CI-USB-1
Interface for connecting a RESISTRON temperature controller with diagnostic inter-
face (DIAG) to the PC (USB port). Associated PC visualization software for dis-
playing setting and configuration data, and for recording SET and ACTUAL tempe-
ratures in real time.
Booster
External switching amplifier, necessary for high primary currents
(continuous current > 5A, pulsed current > 25A).
Monitoring current transformer
For detecting frame short-circuits on the heatsealing band.
Used as an alternative to the standard PEX-W2/-W3 current transformer.
