Block diagram

A block diagram illustrates the internal components and signal flow of the 5335 transmitter. It shows the input signal (mV, RTD, lin. R, TC) going through a MUX, PGA, and A/D converter to the CPU. The CPU processes the signal and outputs it via a D/A converter to the 4-20 mA output. Communication is handled by a COMM module. The device is powered by a supply voltage and includes an EEPROM for data storage.

Programming

The 5335 can be configured in three ways:

1. Loop Link: Using PR electronics A/S' communication interface Loop Link and PReset PC configuration software. Loop Link is not approved for communication with devices installed in hazardous (Ex) areas.
2. HART modem: Using a HART modem and PReset PC configuration software.
3. HART communicator: Using a HART communicator with PR electronics A/S' DDL driver.

Connection of transmitters in multidrop mode:

• The HART communicator or a PC modem can be connected across AB or BC.
• Up to 15 transmitters can be connected in parallel for digital HART communication on 2-wires.
• Each transmitter must be configured with a unique number (1-15). Duplicate numbers will cause exclusion.
• Transmitters must be programmed for multidrop mode with a fixed output signal of 4 mA. Maximum current in the loop is 60 mA.
• Communication is via a HART communicator or HART modem.
• PReset PC configuration software can configure individual transmitters for multidrop mode and provide unique polling addresses.

Mechanical specifications

Dimensions: Ø 44 mm, height 20.2 mm.

Mounting of sensor wires

Wires must be mounted between the metal plates.

Entity concept

The Transmitter must be installed according to National Electrical Code (ANSI-NFPA 70) and installed with the enclosure, mounting, and spacing segregation requirements of the ultimate application.

Equipment that is FM-approved for intrinsic safety may be connected to barriers based on the ENTITY CONCEPT. This concept permits interconnection of approved transmitters, meters, and other devices in combinations which have not been specifically examined by FM, provided that the agency's criteria are met. The combination is then intrinsically safe, if the entity concept is acceptable to the authority having jurisdiction over the installation.

The entity concept criteria are as follows:

• Intrinsically safe devices, other than barriers, must not be a source of power.
• The maximum voltage Ui(VMAX) and current li(IMAX), and maximum power Pi(Pmax), which the device can receive and remain intrinsically safe, must be equal to or greater than the voltage (Uo or Voc or Vt) and current (lo or Isc or It) and the power Po which can be delivered by the barrier.
• The sum of the maximum unprotected capacitance (Ci) for each intrinsically device and the interconnecting wiring must be less than the capacitance (Ca) which can be safely connected to the barrier.
• The sum of the maximum unprotected inductance (Li) for each intrinsically device and the interconnecting wiring must be less than the inductance (La) which can be safely connected to the barrier.
• The entity parameters Uo, Voc or Vt and lo,Isc or It, and Ca and La for barriers are provided by the barrier manufacturer.
