Figure 2-11. 3051S MultiVariable RTD wiring connection
Three-wire RTD
A four-wire Pt 100 RTD is required to maintain published performance specifications. A
three-wire Pt 100 RTD may be used with degraded performance. If connecting to a three-wire
RTD, use a four-wire cable to connect the 3051S MultiVariable terminal block to the RTD
connection head. Within the RTD connection head, connect two of the same colored wires from
the 3051S MultiVariable to the single colored wire of the RTD sensor.
Surges/transients
The transmitter will withstand electrical transients of the energy level usually encountered in
static discharges or induced switching transients. However, high-energy transients, such as
those induced in wiring from nearby lightning strikes, can damage the transmitter.
Optional transient protection terminal block
The transient protection terminal block can be ordered as an installed option (Option Code T1 in
the transmitter model number) or as a spare part to retrofit existing 3051S MultiVariable
transmitters in the field. For a complete listing of spare part numbers for transient protection
terminal blocks, refer to Spare Parts” on page 2-37. A lightning bolt symbol on a terminal block
identifies it as having transient protection.
