BASIC INFO
MTL IOP32D IOP Series Surge Protectors Cost effective
IOP32D and IOP-AC each provide surge
protection for two loops or 4 wires
• IOP32 provides surge protection for one loop
or 2 wires
• IOP HC32 provides surge protection for one
high current loop, up to 5A
• IOP-AC provides surge protections for two
120V or 240V AC loops
• Hybrid protection circuit - 20kA rated
surge current
• ATEX & FM certification for IOP32 and IOP32D
• Space saving - width per loop:
IOP32D & IOP-AC 6mm
IOP32 & IOP HC32 12mm
The IOP was conceived to offer protection for both digital I/O and
analogue I/O. The IOP range is the most economical surge protection
solution for I/O offered by Eaton. High packing-density, high protection
level and low price combine to make the IOP a value solution.
The IOP range is cost-effective and still retains a hybrid circuit
comprising 20kA gas discharge tubes and solid state components.
This impressive product is designed to exhibit exceptionally low line
resistance and therefore adds only a tiny voltage drop to the circuit.
Removable terminals are used on the IOP range for ease of
installation, maintenance and for providing a loop disconnect by simply
unplugging the terminals from the side of the module. Wire entry is
angled to assist wiring within limited space enclosures.
The IOP HC32 is ideal for applications requiring up to 5A of
load current. Protection of circuits to drive solenoids, relays, and
actuators is now possible. The IOP AC is ideal for 120V and 240V
AC circuit loops
Fully automatic in operation, IOP devices react immediately to make
sure that equipment is never exposed to damaging surges between
lines or the lines and ground. Reacting instantaneously, the IOP
redirects surges safely to ground and then resets automatically
The versatile design minimizes space. The IOP32D and IOP-AC
models have protection for two loops in a package that is only
12mm wide. The effective space taken, per loop, is therefore only
6mm. For customers desiring single channel integrity, the IOP32 fits
this need exactly.
One simple manual operation clamps modules securely onto DIN
rail, which automatically provides the essential high-integrity ground
connection.
A 10 Year ‘No Fuss’ warranty is available, as standard, for the IOP, so
if a correctly connected device should fail for any reason, simply return
it for a free replacement.
‘Top-hat’ (T-section) DIN rail is generally suitable for mounting IOP
modules although for adverse environments, a specially-plated version
is available from Eaton’s MTL Surge Technologies.
