Product Highlights
The PCR-3PS performs true pulse conversion in both directions — not simply mimicking pulse activity, but verifying the correct sequence of KYZ contact closures before allowing an output to occur. In 3-wire to 2-wire mode, each valid KYZ change of state produces a fixed 100mS output closure. In 2-wire to 3-wire mode, each valid Form A closure produces alternating Form C output state changes.
Built-in transient protection eliminates the need for external suppressors, and the polycarbonate enclosure provides maximum user protection with all powered components enclosed. Euro-type terminal connectors prevent accidental electrical shock, and dual red and green LED indicators allow instant visual status confirmation without additional test equipment.
Features
- Bidirectional conversion — field-selectable for 3-wire to 2-wire or 2-wire to 3-wire KYZ pulse conversion in a single unit.
- Sequence validation — microcontroller verifies correct pulse input sequence before generating outputs, preventing false pulses.
- Fixed 100mS output — in 3-to-2-wire mode, produces a consistent 100mS isolated output contact closure per valid input.
- Solid-state Form C output — dry contacts rated at 250VAC/VDC at 350mA, with input/output isolation voltage of 2500Vrms.
- Built-in transient protection — eliminates the need for external or off-board transient suppressors.
- Euro-type terminal connectors — no exposed conductive parts when wired, providing maximum protection from accidental shock.
- Dual LED indicators — red and green LEDs display input and output status at all times for rapid visual system verification.
