FF PSI-02 24V is a signal converter that transforms continuous analog or DC control signals into defined pulse outputs. Intended for use with a 24 V AC/DC supply, the unit provides two changeover relay contacts with an 8 A switching capacity. The compact device is designed for integration into industrial control panels, automation sequences and sensor/controller interfaces where pulse signaling is required for counting, sequencing or event triggering.
Advantages
The converter offers reliable conversion from continuous to pulse signals using electromechanical changeover contacts, enabling compatibility with legacy relay inputs and simple PLC or counter modules. Its dual changeover outputs allow independent pulse routing or redundant signalling. Rated switching current up to 8 A supports direct control of many loads without additional intermediate relays. The 24 V AC/DC supply requirement allows flexible integration into typical control systems.
Suitable for
- Converting analog or DC control signals to pulse form for counters and pulse-input PLCs
- Interfacing sensors or transmitters with pulse-only inputs
- Sequencing and event triggering in industrial automation
- Direct switching of moderate loads up to the relay rating
When it may not be suitable
This device uses electromechanical relay contacts and is not suitable where solid-state switching or very high switching speeds are required. Applications needing isolation from mechanical contact bounce or extremely high pulse frequency should consider dedicated solid-state converters or optocoupler-based interfaces. Also, it is not intended as a replacement for signal conditioning that requires galvanic isolation beyond standard relay separation.
Key specifications
- Supply voltage: 24 V AC/DC
- Outputs: 2 changeover relay contacts (double throw)
- Maximum switching current: 8 A per contact
- Function: continuous (analog/DC) to pulse conversion
- Intended mounting: control panel / DIN-rail compatible (verify mounting type before installation)
How to use
Connect the 24 V AC or DC supply to the designated input terminals and wire the continuous input signal to the converter’s signal input according to the wiring diagram provided by the manufacturer. Configure the wiring of the two changeover outputs to the receiving device(s) such as counters, PLC inputs or actuators. Verify correct polarity and supply type before energizing. Test the converter operation at low load and confirm pulse timing and contact operation under expected conditions. Follow standard electrical safety practices and isolate power before wiring.
What to consider before purchase
- Required supply type: confirm 24 V AC or 24 V DC compatibility with your system
- Pulse frequency and contact life: ensure relay performance meets your switching speed and endurance needs
- Load current: verify the 8 A rating is sufficient for intended loads or if intermediate relays are needed
- Mounting and installation space: check panel or DIN-rail requirements
Usage recommendations
For reliable long-term operation, use the FF PSI-02 24V within its rated current and switching frequency limits, provide proper suppression for inductive loads, and perform initial functional tests with the intended control equipment to confirm pulse shape and timing.
