automation platform
Intrinsically safe I/O modules
The Quantum automation platform supports a full range of intrinsically safe
I/O modules designed to interface with a wide variety of sensors or actuators.
Intrinsic safety is a technique that helps to ensure that electrical energy supplied to
circuits in a hazardous area is too low to ignite volatile gases, either from a spark or
from heat release. Intrinsically safe circuits use energy-limiting devices, known as
intrinsically safe barriers, to prevent excessive electrical energy from being applied
to electrical equipment located in hazardous areas. These galvanically isolated
barriers prevent the module from releasing sufficient energy to ignite volatile gases
or vapors in the hazardous area.
Galvanic isolation, in the form of opto-isolators and DC/DC converters, is provided
between the field side output circuitry and the Quantum bus circuitry. The DC/DC
converters provide intrinsically safe power to devices located in hazardous areas.
No external power is required where these modules are installed.
Intrinsically safe I/O modules are designed to fit onto standard Quantum racks.
They can be mounted in any slot position on any Quantum 140 XBP 0pp 00 rack
(3…16 positions).
Each intrinsically safe I/O module requires an I/O connector (140 XTS 332 00).
The connector is color-coded blue to identify it as an intrinsically safe connector.
These connectors are keyed to prevent the wrong connector from being applied to
the module.
The wiring between the intrinsically safe I/O modules and the devices located in the
hazardous area must be separated from other wiring.
This separation can be achieved by either:
b

other wiring
b
wiring. With this method, the wiring must be tied in separate bundles to maintain the
required separation.
