January 2005 Data Sheet 9.80 The HIM HART Loop Interface and Monitor unlocks the full potential of new and in-place smart HART multivariable transmitters and valves. Converts HART to 4-20mA Signals The HIM allows up to three additional analog process variable measurements from a smart device with no additional process penetrations or wiring. Take Full Advantage of ΓLegacy Instruments The HIM lets you leave trusted (and paid for) smart HART transmitters and valves in place, yet still take advantage of all the information they have to offer. Works With Every Smart HART Device With a very simple PC program, the HIM programs in minutes to interface with every HART-compatible monitoring and control device: > The HIM HART Loop Monitor features a compact metalhousing that mounts on a standard DIN-rail or on a surface ԕ Multivariable Mass Flow Transmitters > Dual-Sensor Temperature Transmitters ՕBreak OutӔ up to three analog signals. High/Low process and loop diagnostic alarms. Sets up as a Primary or Secondary Master, or inՓListen Mode. The HIMprovides additional analog signals proportional to a multivariable transmitterԒs primary, second, third or fourth variables, or to user-selectable valve parameters such as stem position. Pressure Transmitters Two relays individually configure to respond to high or low process conditions, or trip when transmitter diagnostics or loop fault conditions are sensed.Օ User configurable to act as aHART Master, or in passive ListenӔ Mode (see Page 5 for details). Coriolis, Magnetic, Ultrasonic and Vortex FlowMeters ՕIsolated output channels. Normal or Burst HART Modes. Delivers superiorprotection against the harmful effects of ground loops and other plant noise. The HIM can beset to monitor smart HART instruments operating in either Normal (Poll/Response) Mode or in Burst Mode (see Page 5 for details).Օ Large, 5-digit display. Shows a selected processvariable in engineering units (input or output) or toggles between any two variables. The display also provides on-site indication of HART instrument fault conditions. pH Transmitters Օ Radar and Hydrostatic Level Transmitters Valve Positioners and Damper Operators > Certifications Canadian Standards Association (CSA-IntՒl) General/Ordinary Locations Non-Incendive Apparatus (except -1PRG models) Class I , Division 2, Groups A, B, C, D Temperature Code: T5@70C Max.

The HIM HART Loop Interface also monitors smart HART valve positioners and damper operators. Its 4-20mA analog outputs can be used to keep track of important parameters such as valve stem position, actuator pressure or temperature. Alarm (relay) outputs can also be set to alert of a smart valve condition such as valve position (open/closed), low actuator pressure, and positioner temperature (high/low). With the MB or MB1AO output types,the HIM converts the HART digital signal to a MODBUS RTU output (Figure 3). This allows HART devices to interface directly with control systems using the...

Figure 4. In just a few minutes, you can set up the HIM using oursingle window Intelligent PC Configuration Software > ListenӔ Mode If the loop has a Primary and SecondaryMaster, the HIM can be set in דListen Mode. In this mode, the HIM can be added to a loop with a Primary and Secondary HART Master because it connects passively without assuming the role of a Master (Figure 5). In ԓListen Mode, the HIM continuously samples HART data from a smart instrument without affecting normal loop operation. Secondary Master ԗWhen a HART-based control system,such as an Asset Management System, is...
