ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) Chapter 1 – Introduction The ControlWave GFC Intrinsically Safe IStran Communication Interface (IStran) allows an intrinsically safe ControlWave Gas Flow Computer / Corrector (CW-GFC-IS) to communicate with a device located in a Division 2 or non-hazardous area.
ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) 1.1 Physical Description The IStran assembly measures 6.25 inches (length) by 4.50 inches (width) by approximately 1 inch (depth). (See Figure 1-2, 1-3, and 1-4.) The IStran assembly consists of the following major components: One IStran printed circuit board (PCB) for the IStran assembly Yellow alodined aluminum base plate (0.060 inch thick) Black anodized cover (0.090 inch thick) Figure 1-2.

IStran PCB Mounted on Base Plate (Cover removed) 1.1.1 IStran PCB The IStran PCB provides two interfaces designated hazardous and nonhazardous. You configure each interface independently to operate in either switched or unswitched mode. Switched Mode Switched mode sets the TX drivers into a high-impedance state to reduce power consumption.

ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) Chapter 2 – Function and Electrical Characteristics You can use the ControlWave GFC Intrinsically Safe IStran Communication Interface (IStran) in both hazardous and nonhazardous environments. 2.1 Hazardous and Non-Hazardous Characteristics Table 2-1 provides the characteristics common to both the hazardous and non-hazardous IStran interfaces: Table 2-1.

Setting Jumper HJP1 2.1.2 Non-Hazardous Interface Typically you connect the non-hazardous interface to a radio or modem located with the IStran assembly in a non-hazardous or Division 2 rated area. Table 2-4 identifies each connector position and the corresponding signal name, and provides a brief description of each I/O point on the non-hazardous interface. Table 2-4.
ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) Table 2-5 provides the characteristics of the non-hazardous interface. Table 2-5. Non-Hazardous Interface Characteristics Description 2-4 Specification NPIN Voltage (When HPOUT is not used) Minimum: Maximum: 5.
ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) Figure 2-2. Setting Jumper NJP1 2.2 Switched & Unswitched Modes You can configure each IStran interface independently to operate in switched or unswitched mode. In switched mode, the TX drivers can enter a high-impedance state to reduce power consumption. The outputs transition smoothly to and from the high-impedance state. Most modern device inputs pull the high impedance IStran output to ground and interpret it as a low, or mark state.
ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) 2.2.1 Configuring the Hazardous Interface for Switched Mode To configure the hazardous interface for switched mode, place the supplied shorting jumper in the HJP1 position marked SW (short HJP1 pins 1 and 2 as shown in Figure 2-1). If you don’t install a jumper at HJP1 the hazardous interface defaults to switched mode.
ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) When hazardous interface signal input HRX3 is at a high (positive) level, NPOUT turns on and can supply power to an external device. When HRX3 is at a low (or negative) level, NPOUT turns off. You determine the voltage drop between NPIN and NPOUT by multiplying the NPOUT load current by the NPIN to NPOUT on-resistance.

ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) Chapter 3 – System Wiring This chapter includes details on grounding and wiring for the IStran. 3.1 Introduction to System Wiring The IStran connects a radio, modem, or other communications device to a ControlWave GFC-IS Flow Computer/Corrector.
ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) 3.3 Cable Length Underwriter’s Laboratories (UL) lists the IStran for use with cable lengths up to 25 feet on either or both interfaces. Typically, you install the IStran in close proximity to the communications device (connected to the non-hazardous interface) and at some distance from the CWGFC-IS (connected to the hazardous interface).
ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) Figure 3-2 is similar to Figure 3-1 except it uses an MDS radio instead of a modem. Figure 3-2. Radio System with Single Power Source Figures 3-3 and 3-4 illustrate an externally powered CW-GFC-IS (without a modem or radio). In this example, the external power source to the non-hazardous interface must not generate more than 16Vdc and must be able to supply at least 8Vdc.

ControlWave GFC IS Communication Interface Manual (CI-CW-GFC-ISTRAN) Chapter 4 – Installation 4.1 Installation Overview The IStran and the communications device reside in a non-hazardous or Division 2 rated area, while the CW-GFC-IS resides in a Division 1, Division 2, or non-hazardous area. You must provide a suitable enclosure for the IStran.
