2231P PR ELECTRONICS Frequency to Analog Signal Converter

The 2231P PR ELECTRONICS is a high-precision, programmable frequency to analog signal converter engineered for process control, turbine flow monitoring, and rotational speed measurement. Designed to accept pulse, frequency, and tachometer signals from a wide range of field sensors—including NAMUR, PNP, NPN, tacho, and TTL contacts—the 2231P PR ELECTRONICS module scales input pulses into proportional 0/4…20 mA or 0/2…10 V analog current/voltage outputs.

Built for heavy industrial panel mounting, the 2231P PR ELECTRONICS features 3-port galvanic isolation (2.3 kVAC) between input, output, and power supply circuits to protect connected control hardware against ground loops and transient spikes. With fast response times, programmable frequency ranges, and reliable DIN rail installation, this module is an essential signal conditioning component for PLC, SCADA, and marine automation systems.

Key Features of the 2231P PR ELECTRONICS

• Universal Frequency Input: Accepts input signals from NAMUR sensors, PNP/NPN transistors, contact closures, magnetic pickups, and tacho generators

• Flexible Analog Output: Converts pulse frequencies directly to proportional 0/4–20 mA current loops or 0/2–10 VDC voltage outputs

• Galvanic Isolation (3-Port): 2.3 kVAC high-voltage isolation between input, output, and power supply prevents signal distortion and protects cabinet electronics

• Wide Frequency Scaling Range: Measures low-frequency pulse counts up to high-speed turbine pulse signals with high accuracy

• Compact DIN Rail Mounting: Standard 11-pole socket or DIN rail enclosure layout simplifies control cabinet wiring and retrofits

• Industrial Grade Reliability: Operational temperature resilience designed for marine engine rooms and factory automation environments
