Chapter 1 – Overview

1.1 Introduction

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.

Fuse XF1
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.

Chapter 2 – Installation

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.

(Shown mounted to the ControlWave EFM or GFC Plus Fabrication Panel)

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
o P4-1 (IN1): Input from Channel 1 Proximity Sensor o P4-2 (GND): Channel 1 Proximity Sensor Common

2.2.1 Field I/O Wiring

Figure 2-3 illustrates the two primary ISProx wirings.
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).
