INTRINSICALLY SAFE RELAY
BASIC MODELS:
SPST / 8 Pin Plug In
030-120-118
FEATURES:
LED Indicator
Surge Protection
Relay Contact Output
Din Rail Mounting Socket
Included (PF083A)
MADE IN
THE U.S.A.
OPERATION
The Intrinsically Safe Relay provides a safe and reliable method of load control when interfaced with a contact
closure in a hazardous location. When the control switch input is closed between pins 1 and 8, the output relay
becomes energized, and the LED is illuminated. When the control switch input is open, the output relay is deenergized, and the LED is turned off.
TYPICAL APPLICATIONS
Lift station controls where intrinsic safety is required.
Anywhere an interface is required where the contact
closure is in a hazardous location and the controls are
in a non-hazardous location.

INTRINSICALLY SAFE RELAY
Notes for UL Control Drawing 0301:
1.
All intrinsically safe wiring shall be separated from non-intrinsically safe wiring. Refer to article 504 of the
National Electric Code (ANSI/NFPA 70) for installation of intrinsically safe wiring.
2.
Maximum distance between unit and switch contacts is 1000 feet.
3.
Switch contact shall be any non-energy storing or generating switch type device containing no
capacitance or inductance.
4.
Device must be installed in MPE socket P/N DS-8-A or PF083A and with locking clips attached to base.
5.
Cable capacitance plus intrinsically safe equipment capacitance (Ci) must be less than the marked
capacitance (Ca) and cable inductance plus intrinsically safe equipment inductance (Li) must be less
than the marked inductance (La) shown any barrier.
6.
The simple apparatus (Float Switch) connected to the ISR shall not be mounted on other electrical
apparatus that has a voltage and current rating higher than the ISR (See Enity Parameters Voc and Isc
below). A simple apparatus (Such as a Float Switch) is defined as an electrical component or combination
of components of simple construction with well defined electrical parameters that does not generate more
than 1.5V, 100mA and 25mW, or a passive component that does not dissipate more than 1.3W and is
compatible with the intrinsic safety of the circuit in which it is used.
7.
If the electrical parameters of the cable are unknown, then a capacitance value of 60pF/ft – and an
inductance of 0.20uH/ft are to be used.
8.
Entity Parameters: Voc = 9.33V
Isc = 0.218mA
Ca = 3.6uF
La = 100mH
