Schneider LTMR08PFM Motor Management Controller

FAQ

Q1: What is the Schneider Electric LTMR08PFM used for?
A: It is a TeSys T motor management controller used for monitoring, protection and control of industrial motors.

Q2: What motor current range does the LTMR08PFM support?
A: It supports a motor measurement-current range of 0.4–8 A.

Q3: What power supply does the LTMR08PFM require?
A: It requires 100–240 VAC, 50/60 Hz, with a permitted supply range of approximately 93.5–264 VAC.

Q4: Does the LTMR08PFM support PROFIBUS communication?
A: Yes. It uses PROFIBUS DP over a 2-wire RS485 interface, supporting addresses from 1 to 125 and transmission rates from 9.6 kbit/s to 12 Mbit/s.

Q5: How many digital inputs and outputs does it have?
A: The controller provides 6 logic inputs and 3 logic outputs. It also has 1 NO + 1 NC fault-signaling contact and 3 additional NO contacts.

Q6: What motor protection functions are available?
A: It supports thermal overload, overload, phase failure, phase imbalance, locked rotor, earth leakage, load fluctuation and power-factor variation monitoring/protection.

Q7: What is the difference between LTMR08PFM and LTMR08PBD?
A: Both are 0.4–8 A TeSys T PROFIBUS DP controllers, but the LTMR08PFM uses 100–240 VAC, whereas the LTMR08PBD uses 24 VDC.

Q8: What are the dimensions and weight of the LTMR08PFM?
A: The controller measures approximately 91 × 61 × 122.5 mm (W × H × D) and weighs approximately 0.53 kg.
