Overview
The Bardac 3600XRi is a fully isolated DC motor controller belonging to the Bardac 3600 series family. Bardac Drives offers a range of isolated dc thyristor 4-quadrant drives, and in the 3600XRi model range each drive has the same features and terminals. This controller is an open-chassis component for use in a suitable enclosure. The 3600XRi is engineered for high-performance speed and torque regulation in demanding motor control applications.
Key Features
- Fully Isolated Control Circuitry – Separate armature and field connections with isolated signal conditioning
- 4-Quadrant Regenerative Operation – Enables reversing and regenerative braking control
- Multiple Current Ratings – 16A, 32A, or 36A variants for flexible application scaling
- Dual Supply Voltages – Dual supply voltage 110 / 230 VAC, 50/60Hz
- Speed Reference Options – Speed reference +/-10V or 4-20mA, speed trim input
- Adjustable Ramps and Limits – Independent up & down ramps in FWD & REV, separate adjustable current limits motor/brake
- Indicator LEDs – LEDs for + current, – current, stall & stall timer
- Momentary Contact Reversing – Momentary contact for reversing applications

Compatibility & Replacements
Compatible With
- Shunt-wound DC motors (separately excited or permanent magnet motors with rated voltage matching controller output)
- Brushed DC motors with armature inductance up to 50 mH
- Industrial control cabinets and enclosures
- Standard 110V or 230V single-phase AC utility power (50 or 60 Hz)
Replaces / Drop-In Replacement For
The 3600XRi series is available in multiple current ratings. If upgrading a lower-current model, verify that the 3600XRi/32 (32A) or 3600XRi/36 (36A) variant is mechanically and electrically compatible with your existing installation. Direct compatibility depends on the specific variant previously in service. In the 3600XRi model range each drive has the same features and terminals; select the appropriate model depending on the motor current and the available supply voltage. Consult the previous drive specification sheet to confirm terminal layout and voltage rating equivalency.
Works With
- Analog speed reference: 0–10V or ±10V signal input
- Analog current control: 4–20mA speed command
- Momentary contact relay switches for forward/reverse/stop control
- External armature choke (recommended for low time-constant motors)
- Shielded signal cabling with proper earth termination for EMC compliance
- Optional drive.web smarty module for Ethernet networking and Modbus TCP/RTU integration
