Series-DRN4

PWM/Analog/Floating Point to Resistance Output Interface Device

Converts control signals to resistance output: DRN3.1 modules accept analog, pulse, floating point, and triac inputs and convert them into a proportional resistive output.
Ideal for legacy control upgrades: Directly replaces variable resistance controllers by simulating a slide wire or rotary potentiometer.
Flexible input compatibility: Supports 0-5 VDC, 0-10 VDC, 0-15 VDC, 0-20 mA, 4-20 mA, pulse, and floating point control signals.
Multiple resistance network options: Available resistor networks include 0-135 Ω, 0-270 Ω, 0-500 Ω, 0-1K Ω, 0-10K Ω, 0-15K Ω, and 0-20K Ω ranges.
Reliable fail-back operation: On-board fail-back relays allow the circuit to revert to the original controller signal if supply power is lost.
Built for actuator and sensor simulation: Well suited for electronic potentiometer applications, electric actuator control, and resistive sensor simulation.
No-wrap output protection: The resistance output stops at the selected minimum or maximum value instead of wrapping around, helping maintain predictable control.
Panel-friendly design: Compact snaptrack mounting, captive screw terminals, and optional DIN rail adapter support clean control-panel installation.
Durable interface performance: Form C relays, 256-step output resolution, RoHS2/WEEE compliance, and ACI’s two-year limited warranty provide dependable long-term use.
