3 Section ISProx SENSOR BOARD INTRODUCTION. GENERAL DESCRIPTION Bristol s ControlWave Series Intrinsically Safe Proximity Sensor Interface Board (herein referred to as the ISProx Board ), provide an intrinsically safe interface to one or two industry standard (see Specs. & Entity Parameters) Variable Impedance Proximity Sensors (NAMUR Gap Sensors) and 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 have been designed for installation and operation within an area requiring either Class I, Div. (Groups A, B, C and D) or Class I, Div. (Groups C & D) certified equipment. ISProx modules have been designed to provide the following features: ISProx Boards are Intrinsically Safe and may be used as barrier between an I.S. device and a nonhazardous installation Five (5) Terminal Blocks provide field device wiring flexibility and convenience. - Terminal Block P accommodates 6-4 Vdc bulk input power input - Terminal Blocks P 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). - Two Input Sensor Term. Blocks (P4 & P5) provide an Intrinsically Safe 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. ISProx COMPONENT IDENTIFICATION ISProx components that the user should become familiar with are discussed herein. These components include Connectors P through P5 and Fuse XF. Terminal Blocks ISProx Board s are provided with five Terminal Blocks which accommodate up to #6 AWG size wire. Terminal Block designation and connections are provided in Tables through 6.

If an abnormal condition should occur in circuitry within the ISProx, XF will blow and all current will cease to flow. ISProx also protects against field wiring short circuits.

6 Section ISProx SENSOR BOARD INSTALLATION. ISProx MOUNTING ISProx Boards are either Snap Track mounted (on edge) to the Fabrication Panel within a ControlWave EFM/GFC Plus enclosure or panel mounted and glued to the inside of a ControlWave Corrector Instrument Front Cover.

ISProx wiring requirements are dependent on the following considerations: ISProx Site Environment ISProx Boards are suitable for installation where equipment must be certified for operation in either Nonincendive - Class I, Division (Groups A, B, C & D) or Intrinsically Safe - Class I, Division (Groups C & D) environments. Proximity Sensor Site Environment and ISProx Board Input 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 nonhazardous (unregulated) area or either Nonincendive - Class I, Division (Groups A, B, C & D) or Intrinsically Safe - Class I, Division (Groups C & D) environments. ISProx Board Output Interface 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: PIP-CW ISProx Page - 5
