LD220T Series - Dual channel boxed loop detector with RS485 communications

The LD220 is a series of dual channel inductive loop detectors. The use of microprocessor and surface mount technology enables a large number of functions to be incorporated into a small package. The LD220 is compatible with most dual channel detectors on the market and is easy to set-up and install. All configuration is done through the communications port.

The LD220 is supplied with a RS485 communications port. The LD220R is supplied with a RS232 communications port.
Typical applications in the parking and access control environments are safety loops, arming loops and entry or exit loops and direction logic with counting.

The LD220 consists of an inductive loop detector with an integral RS485 communications port. The unit has been developed to enable remote monitoring and control of the loop detector over a RS485 network. The communications allows access to internal setup parameters such as sensitivity, timers, as well as counters. The LD220 can be multi-dropped on the RS485 network with other detectors and logic units, or linked to a PC running software for configuration and monitoring of the parking system. Non volatile memory is used to store counters and all configuration parameters.
