Another loop may contain two passive chart recorders, a passive pressure transmitter, and a 24 V battery. (The battery is the active device). Note that a 4-wire instrument has a power supply input separate from the current loop. Panel mount displays and chart recorders are commonly termed 'indicator devices' or 'process monitors'.
Introduction to the TwoTel 248-295-0880 Fax 248-624-9234 sales@acromag.com www.acromag.com 30765 Wixom Rd, Wixom, MI 48393 USA INTRODUCTION TO THE TWO-WIRE TRANSMITTER AND THE 4-20MA CURRENT LOOP 6 3. Transmitter: This is the device used to transmit data from a sensor over the two-wire current loop. There can be only one Transmitter output in any
22-wire (“loop-powered”) transmitter current loops. It is possible to convey electrical power and communicate analog information over the same two wires using 4 to 20 milliamps DC, if we design the transmitter to be loop-powered. A loop powered transmitter connects to a process controller with only two wires, which is why loop-powered transmitters are synonymously known as 2-wire transmitters:
TMP01 4 to 20mA Current Loop – Circuit Wiring DiagramsHere is the schematic diagram of the circuit: Temperature setting pins and the open collector outputs can be connected to do any local control of switching. The current is calibrated to 4 mA at a temperature of -40°C, to 20 mA for +85°C and proportional to the voltage on the VPTAT. The output current is determined by folowing equation:
Basics of Instrument Loop Diagrams ~ Learning ...Instrument loop diagrams are also called instrument loop drawings or loop sheets. These set of drawings are more detailed than process and instrument diagrams (P&IDs). Loop diagrams are the most detailed form of diagrams for a control system and thus it must contain all details omitted by PFDs and P&IDs alike.
Basics of The 4The loop current flows back to the controller through the wire, and then flow through resistor, R, to ground and returns to the power supply. The current flowing through R produces a voltage that is easily measured by the analog input of a controller. For a 250 ohm resistor, the voltage will be 1VDC at 4mA and 5VDC at 20mA. As the diagram above ...
4I have recently purchased the 4-channel 4-20mA current Loop Receiver and have a wiring question. I have a 4-20mA sensor that expects 14-24VDC to be supplied on the sensor + connection and returns the 4-20mA signal on the sensor - connection. There is no “GND” connection. How would I hook this up to one of the channels of the 4-20mA current Loop Receiver? I see 6 screw terminals on the PCB ...

Back to Basics: The Fundamentals of LoopLower Cost. Loop-powered devices are often much lower cost than other process control devices with built-in high power electronics. This is simply because the expensive components that could be included in these devices such as power supplies, mechanical relays, or advanced digital or analog signal output components are omitted in order to limit the amount of power necessary to operate the device.
