BL100B: Barrier Logic with loop detector

Power supply

200 - 260VAC 50Hz 1.5VA

NMI/MI Input

This input may be activated by a potential free relay contact or open collector NPN transistor output. This input is isolated from the logic.

Beam Input

This input may be activated by a potential free relay contact or open collector NPN transistor output. This input is isolated from the logic and is used to keep the barrier open when a vehicle has broken the beam.

Raise/Lower Output Relay

These outputs are relay contacts rated at 5A/220VAC.

TVI Output Relay

This output is a normally closed relay output rated at 0.5A/35VDC.

Indicators

LED indicators show: Power, Barrier Raised and Loop Detector.

Detector tuning range

15 - 1500uH

Loop Frequency

Approx. 23 – 130KHz

Environmental tracking

Automatic Compensation

Protection

Loop isolation transformer with zener diodes and gas discharge tube.
