SY F-P-O Frequency to Analog Signal Transmitter IC

Product Advantage

1.Precision FV/FI Conversion on a Chip

Accepts 0–1KHz, 0–5KHz, or 0–10KHz frequency inputs (3.5–50V P-P). Converts linearly to 0–2.5V/0–5V/0–10V voltage or 0–10mA/0–20mA/4–20mA current. Non-linearity below 0.1%, 100 ppm/°C gain drift, and 25 μV/°C output drift for precise, stable conversion across the full industrial temperature range.

2.3,000VDC Two-Way Isolation

Built-in isolated DC/DC supply provides 3KVDC galvanic isolation between auxiliary power (5/12/24VDC) and the signal path. Eliminates ground loops between the frequency source and the receiving PLC/DCS. Ideal for noisy motor-drive environments where input-side transients would otherwise corrupt the analog output.

3.Plug-and-Play SIP-12 Footprint

Standard single-inline 12-pin package with minimal external components—just add gain and zero trim potentiometers for current-output configurations. Voltage-output versions ship factory-calibrated and require no trimming. UL94V-0 flame-retardant molding suits direct PCB mounting.

4.DIN-Rail Versions Available

Pre-assembled DIN 1X1 (one channel) and DIN 1X2 (two channels) modules embed the SY F-P-O IC on a 79.5×32.5mm PCB with front-accessible zero/span trimmers for field calibration. Ideal for control cabinets requiring quick installation without PCB design effort.

5.Industrial Temperature -20 to +70°C

Rated for harsh environments with 1000–1500VAC isolation test (1 min). Output ripple under 7mV without external filtering. 2KΩ minimum load on voltage outputs. Covers tachometer signal conditioning, VFD frequency monitoring, generator speed sensing, and transformer frequency detection.

Technical Parameters

Product Uses

1.Rotating equipment speed monitoring: The module converts pulse frequency signals from speed sensors (0-10kHz) into standard analog outputs (4-20mA or 0-5V) for PLC/DCS monitoring. 3KVDC isolation protects control systems from field-side transients. Suitable for motors, turbines, and generators.

2.Variable frequency drive (VFD) frequency signal acquisition: The module isolates and converts VFD output frequency signals to analog voltage or current for data acquisition. SPI-12 IC package enables compact integration into drive control boards. Adjustable gain and zero via external potentiometers.

3.Flow meter pulse signal conversion: The module converts pulse outputs from turbine or vortex flow meters (0-5kHz) to 4-20mA analog signals. Supports input voltages from 3.5V to 50V P-P, accommodating various flow meter output levels. Non-linearity <0.1% FSR ensures accurate flow rate representation.

4.Transformer working frequency detection: The module monitors power transformer operating frequency by converting AC frequency signals to analog outputs. 3KVDC isolation provides safety barrier between high-voltage transformer circuits and low-voltage monitoring systems. Operates across -20°C to +85°C for substation environments.

5.Industrial automation production line counting: The module converts pulse signals from proximity switches or encoders on assembly lines to analog signals for production rate monitoring. DIN35 rail-mount option enables easy cabinet integration. Zero and span adjustable on-site via side-mounted potentiometers.

6.Remote wireless data transmission signal conditioning: The module conditions frequency-modulated signals from wireless data transmission systems into stable analog outputs. Low power consumption (30mA at 24V) suits battery-powered remote stations. 1500Vrms isolation prevents ground loops between remote antennas and receivers.
