PD232 / PD234 Enhanced Dual Channel Inductive Loop Vehicle Detectors

An updated, reliable dual channel detector with built-in advanced diagnostic capabilities and heavy duty 5A relays
Standard options include direction logic and programmable presence or pulse outputs.
Models are available for operation with 240V AC and low voltage 9 – 40 V AC/DC supplies.

These are genuine Nortech products that comply with Australian Electrical Safety standards and are NOT the cheap Chinese fakes being offered by online vendors.

High – 0.01% Δ L/L
Med – High 0.05% ΔL/L
Med – Low 0.1% ΔL/L
Low – 0.5% ΔL/L

Frequency: Four step adjustable on face plate, High, Med-High, Med-Low, Low (frequency determined by loop geometry)
Output Configuration: 1 output relay per channel (fail safe in Presence mode or fail secure as optional model)
Pulse output: Approx. 150ms duration (Factory option 250ms)
Presence Time: Selectable – limited or permanent  presence. (Limited-presence 1 hour for 3% ΔL/L)
Output modes:
1. Presence or pulse outputs are independently selectable for CH 1 and CH2
2. Direction logic output – A to B (CH1) & B to A (CH2) pulse or presence outputs available.

Indications: The face-plate indications are a single power LED plus individual channel LED’s
1. Tuning-on (flashed) or slow flash in A/B logic mode
2. Undetect – LED off.
3. Detect – LED on steady
4. Fault – on with short off pulse (manual reset required to restore)

Protection: Loop isolation transformer, zener diode clamping on loop inputs and gas discharge tube protection
