LD140 Series Loop Detectors

The LD140 series uses cutting edge technology to provide a diagnostic loop vehicle detector with selectable parameters programmable from the buttons on the front panel. Diagnostic capabilities provide the flexibility to also act as a loop analyser.

Designed as a multipurpose inductive loop vehicle detector for use in parking, access control and traffic applications
Typical applications are as safety loops for barriers or gates, arming loops for activating card dispensers, entry or exit loops and vehicle counting.

In addition to changing the function of relays and setting the loop sensitivity, there is also an onboard vehicle counter
The LD140 counts vehicles as they move over the loop and keeps its value in the event of a power failure, the counter has a maximum count of 999999
The diagnostic capabilities enable you to quickly check loop inductance, loop faults and set the sensitivity very accurately ensuring no false triggers.

	LD140	LD142
Power Requirement	240vac	12/24vac/dc
Presence Relay 1	Change over contact 0.5A / 220vac (Failsafe – normally energised) (Fail secure – normally de-energised)
Presence Relay 2	Change over contact 0.5A / 220vac (Pulse on detect – normally de-energised) (Pulse on undetect – normally de-energised) (Presence mode – normally de-energised) (Loop fault mode – normally energised)
Response Time	Default approximately 120ms after the vehicle enters loop. Adjustable 50ms to 9.00 seconds
Indicators	LED indicators show: detect state
Detector Tuning Range	15—1500uH
Loop Frequency	Approx. 23 -130 KHz
Power Fail Memory	20 Seconds
Environmental Tracking	Automatic Compensation
Protection	Loop isolation transformer with zener diodes and gas discharge tube.
Connector	11 Pin connector on the rear of the unit.
Operating Temperature	-20°C to 70°C
