Remote Automation Solution’s ControlWave Series Intrinsically Safe
Proximity Sensor Interface board (or the “ISProx board”) provides an
intrinsically safe interface to one or two industry-standard variable
impedance proximity sensors (see Specifications & Entity Parameters)
(NAMUR Gap Sensors). The module also conditions and converts these
signals to Open Drain outputs (DOs), which in turn drive ControlWave
EFM/GFC/Corrector digital inputs (DIs) or counter inputs (HSCs).
ISProx boards are snap-track mounted and are designed for installation
and operation within an area requiring either Class I, Div. 2 (Groups A,
B, C and D) or Class I, Div. 1 (Groups C & D) certified equipment.
ISProx boards provide the following features:
ISProx boards are intrinsically safe (IS) and may be used as barrier
between an IS device and a nonhazardous installation.
Five (5) terminal blocks provide field device wiring flexibility and
convenience:
o Terminal block P1 accommodates 6 - 24 Vdc bulk input power
input.
o Terminal blocks P2 and P3 provide open drain outputs (DOs)
(converted from the proximity sensor inputs) which are wired to
ControlWave EFM/GFC/GFC Corrector digital inputs (DIs) or
counter inputs (HSC).
o Two Input Sensor terminal blocks (P4 & P5) provide an IS
interface to two inductive proximity sensors (two-wire) (with
entity parameters matching those of the ISProx).
Snap-track mounting accommodated.
Small size minimizes panel space requirements.

1.2 ISProx Component Identification
This section discusses components of the ISProx board with which you
should be familiar. These components include terminal blocks P1
through P5 and fuse XF1.
Terminal Blocks
ISProx boards have five terminal blocks which accommodate up to
#16 AWG size wire. Tables 1-1 through 1-5 provide terminal block
designation and connections.

The XF1 fuse (0.125A fast blow 2 x 7 mm) provides protection for
the ISProx and associated field I/O. If an abnormal condition occurs
in the ISProx circuitry, the XF1 blows and all current stops flowing.
The ISProx also protects against field wiring short circuits.
This chapter explains how to install ISProx boards into the
ControlWave.
2.1 ISProx Mounting
ISProx Boards are either snap-track mounted (on edge) to the
fabrication panel within a ControlWave EFM/GFC Plus housing or
panel-mounted and glued to the inside of a ControlWave Corrector
Instrument front cover. Figure 2-1 provides ISProx PCB dimensions
and Figure 2-2 shows a snap-track mounted unit.

2.2 ISProx Sensor Board Wiring
Terminal Blocks are equipped with compression-type terminals that
accept a #16 AWG size wire. To make a connection, insert the wire’s
bared end (1/4” max.) into the clamp beneath the screw and then tighten
the screw. ISProx terminal blocks function as follows:
P1: Interface for ISProx PCB’s bulk input power
o P1-1 (VDD): +6 to +24 Vdc Bulk Power Input for Div. 2
Barrier Operation) (+6 to +9 Vdc for IS area)
o P1-2 (GND): 6-24V Power Common/Return)
P2:Interface for Open Drain DO #1 (Converted from Proximity
Sensors)
o P2-1 (DO1): Channel 1 Open Drain Digital Output
o P2-2 (GND): Circuit Ground
Note: Use in conjunction with ground from P1-2, P4-2, or P5-2.
P3: Interface for Open Drain DO #2 (Converted from Proximity
Sensors)
o P3-1 (DO2): Channel 2 Open Drain Digital Output
o P3-2 (GND):Circuit Ground
Note: Use in conjunction with ground from P1-2, P4-2, or P5-2.
P4: Interface for Input from Proximity Sensor #1

2.2.1 Field I/O Wiring
Figure 2-3 illustrates the two primary ISProx wirings.
ControlWave ISProx Board
Figure 2-3. ISProx Wiring Diagram
ISProx wiring requirements depend on the following considerations:
ISProx Site Environment
o ISProx boards are suitable for installation where equipment must
be certified for operation in either Nonincendive - Class I,
Division 2 (Groups A, B, C & D) or Intrinsically Safe - Class I,
Division 1 (Groups C & D) environments.
Proximity Sensor Site Environment and ISProx Board Input
o ISProx boards can be interfaced to inductive proximity sensors
that match the ISProx Entity Parameters. These Proximity
Sensors may be installed and operating in a non-hazardous

(unregulated) area or either Nonincendive - Class I, Division 2
(Groups A, B, C & D) or Intrinsically Safe - Class I, Division 1
(Groups C & D) environments.
ISProx Board Output Interface
o ISProx boards functionally interface the output of a proximity
sensor to one or two ControlWave EFM/GFC/Corrector digital
inputs (DIs) or counter inputs (HSC). ISProx functionally
provides one of the following I/O interfaces:
o Intrinsically Safe Barrier installation and interface (Class I,
Div. 1) between a proximity sensor (in an Intrinsically Safe
area) and DI/HSC associated with a ControlWave
EFM/GFC/Corrector that is situated in either a
Nonhazardous or Nonincendive (Class I, Div.2) environment
(see Figure 2.3A).
o Intrinsically Safe barrier interface between a proximity
sensor (in an Intrinsically Safe area) and DI/HSC associated
with a ControlWave EFM/GFC/Corrector that is situated in
an Intrinsically Safe (Class I, Div. 1) environment (see
Figure 2.3B).
o Nonhazardous or Nonincendive (Class I, Div.2) installation
and Nonincendive barrier interface between a proximity
sensor (in a Nonhazardous or Nonincendive area) and
DI/HSC associated with a ControlWave
EFM/GFC/Corrector that is situated in either a
Nonhazardous or Nonincendive (Class I, Div.2) environment
(see Figure 2.3A).
