VSSC ..............surge protection for I/O
What’s in a name ?
Varitector = Variable Protector
SSC = Signal Screw Connection
What is new?
The 20+ year old DKU Series is being replaced
with a new pluggable style/construction with more
functionality.
VARITECTOR
VSSC
What approvals are there?
UL is available now
Class & Division and ATEX are planned
for 2012.
DK Series
What is the availability?
The new range includes more than 100 different articles.
These are in stock – either in Richmond (high runners) or Detmold.
Where is I&C Surge protection used?
 Industries where plant / signals are outside, e.g….
 Sewage treatment plants
 Water treatment and pumping stations
 Chemical plants
 Refineries
 Customers are:
 Municipalities (+ their SIs)
 Plant end-users (above)
 Package plant OEMs (separators, dryers, coolers, effluent
treatment, chemical dosing, pumping)
VARITECTOR SSC – Surge Protection for C&I
Easy to use:
 Direct PE-contact by fit on the rail
Screw connection:
Torx-slot screw
Cross section for 0.5mm² to 6mm²
High tightening torque (0.8Nm)
Two in one:
Terminal block with integrated
surge protection
Space saving in the cabinet:
only 6.2mm width per loop
More than 100 variants:
 current loop and binary signals

Selection ............... step 1
What information do we need to be able to specify a product? Here is a guide.
S
Signal type…?
Analog, status, fieldbus, telecom
N
Nominal voltage….?
12V, 24V, 48V, 60V, 120V, 230V……
I
Indication of status needed…?
Locally and /or Remotely
F
Frequency….?
Fast-changing signals, Fieldbus or Telecom ?
F
Floating or Ground referenced…? Process measurement signals are often floating.
Think….. S.N.I.F.F…. !
VSSC .........Typical customer questions
“I need surge protectors for 24V lines / signal lines / measurement loops / PLC inputs”
“……… or for bus / RS485 / RS 422 / RS232 / telephone networks”
“I’m looking for over-voltage / lightning / transient protectors for …..control loops”
“I need some of your MTL / SD modules….. ”
“……… or DK 4 U, DK 5 U, DK 6 U …or MCZ OVP”
