Module điểu khiển và mở rộng vùng LCM-320 and LEM-320

Voltage: 24 VDC nominal, 27.6 VDC maximum.

Maximum loop length: The maximum wiring distance of an
SLC using 12 AWG (3.1 mm²) twisted-pair wire is 12,500 feet
(3810 m) per channel. For a twisted-unshielded pair, 12 AWG
(3.1 mm²) to 18 AWG (0.78 mm²):
–Distance with 12 AWG: 12,500 ft (3,810 m).
–Distance with 14 AWG: 8,000 ft (2,438 m).
–Distance with 16 AWG: 4,875 ft (1,486 m).
–Distance with 18 AWG: 3,225 ft (983 m).
–50 ohms maximum per length of Style 6 & 7 loops.
–50 ohms maximum per branch for Style 4 loop.
Maximum current: for LCM-320:130 mA; for LEM-320:100
mA; for single SLC loop:400 mA maximum.
