WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to
serious injury or death. This device does not include the self-checking redundant circuitry necessary
to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.
Overview
VALU-BEAM SMI912 Series sensors are designed for intrinsically safe operation in hazardous atmospheres. They are
certified by FM Approvals and CSA as being intrinsically safe when used with approved intrinsic safety barriers.
SMI912 Series sensors may be wired for either two- or three-wire current-sinking operation. In the three-wire hookup,
which requires two intrinsic-safety barriers, the sink current is 15 mA. The two-wire hookup, which requires one barrier,
sinks ≤ 10 mA (OFF state) and ≥ 20 mA (ON state).

SMI912 Series sensors feature rugged, encapsulated construction, along with adjustable sensitivity and switchable light or
dark operate. They also include Banner's exclusive Alignment Indicating Device system, which lights an indicator LED
whenever the sensor “sees” its modulated light source, and pulses at a rate proportional to the received light signal
strength.
Intrinsic safety barriers and current trip point amplifier model CI3RC2 are also available (see Accessories).
Installation Notes
WARNING: Explosion Hazard
Do not disconnect equipment unless power has been switched Off or the area is known to be non-
hazardous.
FM Installation
1. Barriers must be installed in accordance with manufacturer's instructions.
2. Barrier entity parameters must meet the following requirements:
• Voc or Vt ≤ Vmax Ca ≥ Ci + Ccable
• Isc or It ≤ I max La ≥ Li + Lcable
3. Maximum non-hazardous area voltage must not exceed 250V.
4. For guidance on installation, see ANSI/ISA RP12.6, “Installation of Intrinsically Safe Instrument Systems for Hazardous
(Classified) Locations.”
5. The sensors are suitable for installation without barriers in Class I Div. 2 Groups A, B, C, D; Class II Div. 2 Group G;
and Class III Div. 2, when installed in (or through the wall of) a suitable enclosure with provision for connection of rigid
metal conduit per the National Electrical Code, as acceptable to the local inspection authority having jurisdiction.

Wiring Connections
SMI912 Series sensors are certified intrinsically safe ONLY when used with certified energy-limiting intrinsically safe
barriers. Banner does not manufacture such barriers; however, our applications engineers can refer you to suppliers of
certified barriers that will interface with Banner sensors. SMI912 Series sensors may be wired using Banner Current
Amplifier Control Module CI3RC2. Note from the wiring diagrams that the installation may be made with either a single
barrier (2-wire hookup) or with a double barrier (3-wire hookup). Emitter-only units (SMI91EQD, ESRQD, and EFQD) use
the 2-wire hookup; all other models use either 2- or 3-wire hookup.
In the 2-wire configuration, the sensor will act as a current sink, drawing less than 10 mA in the OFF state and more than
20 mA in the ON state. The user must provide a current sensing device (“current sensor” in the diagram) to convert the
current to a logic level. In the 3-wire configuration, the output may be used directly to control loads of less than 15 mA.
In selecting the barrier, it is important to consider the barrier's resistance. The sensor must have at least 10 volts across
the brown and blue power leads for proper operation, and the barrier will cause a voltage drop due to its resistance. The
formula that determines how much resistance is allowed is:
R = 40 (supply voltage – 10 volts). If the supply voltage is 24 V dc, then the maximum resistance is 560 ohms. If the
supply voltage is 18 V dc, then the maximum resistance is 320 ohms. This includes the resistance of any current sensing
device used (in the 2-wire configuration), so the barrier resistance must be further reduced by the current sensor
resistance.
Note that, in the 3-wire hookup, the positive load barrier is in series with the load. This will result in an apparent
saturation voltage of the output that is higher than the sensor output by the amount of I × R (current times resistance)
drop through the barrier.
A “positive input” barrier is required for both supply and for load. The sensor’s blue (negative supply) lead is normally
connected to the ground terminal of the barrier.
The user is responsible for proper installation and maintenance of this equipment, and must conform with the certification
requirements relating to barriers and to maximum allowable capacitance and inductance of the field wiring. If in doubt
about these requirements, our applications engineers can refer you to the appropriate authority.

Current Trip-Point Modules
Current Trip-Point Module
Model Description
CI3RC2
• Self-contained module converts the SMI912 sensor’s current output signal to a trip point switch.
• SPDT electromechanical relay switches loads that draw up to 5 amps. The SPST solid-state relay can switch a dc load
of up to 30 V dc, max.; 20 mA max.
• Powered by either 105 to 130 V ac or 210 to 250 V ac.
• Supplies dc power to operate a single sensor or both the emitter and receiver of one SMI Series opposed-mode
sensor pair. The sensor's input to the CI3RC2 is protected against short circuits. Built-in circuit diagnostics indicate
an input overload by flashing an LED status light.
• Module has two isolated output switches, a 5-amp rated SPDT electromechanical relay and a solid-state transistor
switch used for logic-level interfaces.
• May be ordered either alone or as a part of a kit.
