GD 100 Single-Channel Vehicle Detector

The GD100 is a cost-effective, single-channel, din-rail mounted, microprocessor-based detector used to detect vehicle presence by means of an inductance change caused by the vehicle passing over a wire loop buried under the road surface. With front panel switches to allow for different loop frequency settings, sensitivity
settings and mode settings, the GD100 is a compact, low-voltage detector specifically designed for the Gate & Door market.

APPLICATIONS

· Parking barrier control
· Vehicle access control
· Motorized gates and doors
· Industrial control systems

FEATURES

· Compact Size:

This compact industry-standard housing combines all the requirements regarding features and functionality and allows this detector to be incorporated into any new or existing vehicle detection system.

· Selectable Fail-Safe/ Fail Secure:

Allows a selectable output for either Fail Safe or Fail Secure operation.

· Loop Isolation Protection:

The loop isolation transformer provides protection against lightning and transient damage and allows for operation with single point to ground sensor loops.

· Loop Frequency Indication:

The possibility of cross-talk (interference) between adjacent loops/ detectors can be determined by a visual display, and eliminated by changing the frequency settings.

· Automatic Sensitivity Boost (ASB):

Ensures reliable detection of all vehicle types.
