TC_ / TC_CV current transformers with built-in measuring converter (20 mA / 4–20 mA output)
Country: Spain · Model: TC_ / TC_CV
TC_ and TC_CV combine a feed-through current transformer and a measuring converter and deliver an analog DC signal of 20 mA or 4–20 mA instead of an AC 1 or 5 A. The signal goes straight to the input of a PLC, SCADA controller or recorder, so the current of motors, pumps and fans is monitored without a separate converter.

Description
TC40, TC60 and TC80 have windows for 40×10, 60×10 and 80×30 mm busbars or Ø32, Ø50 and Ø65 mm cable, a 20 mA output, class 0.5 and a maximum load resistance of 600 Ω. The TC_CV in a plastic housing have a primary current switch, so one device covers several ratings. TC20CV is designed for a 20×5 mm busbar or Ø16 mm cable, TC30CV for 30×10 mm or Ø22 mm, and TC40CV for 40×10 mm or Ø30 mm. The output is 4–20 mA, class 1, the working range is 10–120 % of the rating, and the auxiliary supply is 10–40 V DC. Frequency 50–60 Hz, operating temperature −5…+40 °C, insulation class E (B, 130 °C on request). A CE declaration has been issued for TC_CV.
How to choose
First choose the window to suit the busbar or cable. If the line current is known and does not change, TC_ with a 20 mA output will do, and when the rating may change, take TC_CV with the switch and a 4–20 mA output. TC_ has class 0.5 and TC_CV has class 1, so for more accurate monitoring choose TC_. For an ordinary 1 or 5 A secondary output, look at TUC_ or TU_PS.

FAQ
How does TC_ differ from TC_CV?
TC_ gives 20 mA and class 0.5 with a fixed rating. TC_CV has a primary current switch, a 4–20 mA output, class 1 and a 10–40 V DC supply.
What burden can be connected to the TC_ output?
The maximum load resistance is 600 Ω at a 20 mA DC output.
What working range does TC_CV have?
10–120 % of the rating, and the rating itself is set with the switch.
What are the operating conditions and insulation class?
Frequency 50–60 Hz, temperature −5…+40 °C, insulation class E, class B (130 °C) on request.
