PRODUCT DESCRIPTION
PF-KBP-21Q-3 potentiometer transmitter
POUNDFUL PF-KBP-21Q-3 is a potentiometer transmitter that converts a 0-100% position signal into a linear 4-20 mA DC output. It operates from a 24 V DC supply and accepts switchable potentiometer resistance ranges from 200 ohm to 50 kohm.
The transmitter provides 0.1% full-scale accuracy at 23 +/-5 deg C, output ripple below 0.1% full scale and a response time of 250 ms or less. Its plug-in construction with barrier terminals supports operation from 0 to 55 deg C at 20-95% relative humidity without condensation.
The transmitter provides 0.1% full-scale accuracy at 23 +/-5 deg C, output ripple below 0.1% full scale and a response time of 250 ms or less. Its plug-in construction with barrier terminals supports operation from 0 to 55 deg C at 20-95% relative humidity without condensation.

SYSTEM INTEGRATION
Integrate PF-KBP-21Q-3 into a 4-20 mA position loop
Connect PF-KBP-21Q-3 to a 24 V DC supply and a potentiometer representing 0 to 100% position. Select the input-resistance range that matches the installed sensing element between 200 ohm and 50 kohm, while retaining the transmitter's 2.5 V DC internal excitation arrangement.
Route the linear 4 to 20 mA DC output to the receiving analog input with correct polarity and terminal assignment. The documented performance includes 0.1% full-scale accuracy at 23 +/-5 deg C, output ripple below 0.1% full scale and a response time of 250 ms or less.
Install the plug-in transmitter and barrier-terminal base in the approved enclosure and maintain the documented 0 to 55 deg C operating range with 20 to 95% non-condensing humidity. Commission the loop by checking the 0%, midpoint and 100% positions against the corresponding output current.
Features:
- Selectable 200 ohm to 50 kohm input
- Linear 4-20 mA DC position output
- Endpoint and response-time verification
PF-KBP-21Q-3 integration requires the input-resistance range, 24 V DC supply, terminal assignment and 4-20 mA loop scaling to match.
INTERCHANGEABILITY
Match PF-KBP-21Q-3 input range and loop scaling
Before removal, record the complete PF-KBP-21Q-3 marking, selected potentiometer-resistance range, 24 V DC supply polarity and every barrier-terminal connection. Capture the measured input position and corresponding output current so the existing loop scaling can be reproduced.
Compare the replacement transmitter's 0 to 100% potentiometer input, switchable 200 ohm to 50 kohm range, 2.5 V DC excitation and 4 to 20 mA output with the installed article. Do not select a substitute from enclosure appearance or output type alone.
Fit the replacement to the correct socket, restore the recorded range selection and terminal wiring, then verify output at the lower endpoint, midpoint and upper endpoint. Confirm stable current, correct direction of travel and a response time no greater than 250 ms before returning the loop to service.
Features:
- Recorded resistance range and terminal wiring
- Matched excitation, supply and output signal
- Three-point loop scaling verification
PF-KBP-21Q-3 replacement requires the selected input range, 24 V DC supply, barrier-terminal wiring and 4-20 mA scaling to match.
