We’re also going to analyze a typical instrument field-wiring drawing to show you how PLCs are properly configured for different transducer and transmitter types. A transducer is a device that converts one form of energy to an electrical or electronic signal. A Pressure switch is a two-part device consisting of a sensing transducer and an electrical switch. A pressure switch is a digital device because it has only two possible conditions – open or closed. It is therefore connected to a PLC digital input module. A Pressure Transmitter is a two-part device consisting of a sensing transducer and a circuit that transmits a standard instrumentation electrical signal representing a physical variable being measured. In most applications, the electrical signal is 4 to 20 mA. A Pressure Transmitter is an analog device and is therefore connected to a PLC analog input module. Many people refer to this device as a Transducer. For the sake of simplicity, we’ll continue to refer to it as a Transmitter. A Pressure Transmitter requires a power supply to operate. Most Pressure Transmitters are two-wire types. Transmitters are also available as four-wire types. As the name suggests, a two-wire pressure transmitter has only two wires. These two wires provide power for the transmitter and are also the signal lines! A four-wire transmitter has two wires connected to a power supply and two signal wires connected to the PLC. The power supply can be AC or DC depending on the vendor and model. 1) Digital input – 1756-IF8 We will wire a Gems PS41 series pressure switch to Input 3 of a ControlLogix 1756-IB32 digital input module. The 1756-IB32 module is capable of supporting up to 32 digital input devices. Each additional device would be wired the same as the Gems pressure switch. 2) Analog input – Single-ended and differential The analog module can be wired in two possible modes: Single-ended or Differential. The selection is important as it determines how the module is physically wired. In Single-Ended mode, we can connect 8 two-wire transmitters sharing one power supply. Each transmitter connection is referred to as a Channel. 2) Analog input – 1756-IF8 The 1756-IF8 module is configured for current input during programming in the I/O configuration. We will connect the Wika E-11 two-wire transmitter to Channel 5 of a ControlLogix 1756-IF8 analog module. Details on how to wire more transmitters can be found on the Rockwell Automation website: bit.ly/1756IO 2) Analog input – 1756-IF8 - an industry example Field wiring diagrams vary between companies. In our example, two channels of the 1756-IF8 are wired in Single-Ended Mode. We’ll look at how Pressure Transmitter ZT-P3606 is connected to Channel 0, and ZT-P3610 is connected to Channel 1. Both transmitters share the same +24V DC Power Supply. ============================= Get a RealPars pro membership: learn.realpars.com/bundles/pro ============================= Missed our most recent videos?
