Manufacturer: Reliance Electric, USA

Mounting Type: Standard 19-inch rack-mount plug-in PCB

Product Status: Obsolete / Discontinued (available as refurbished or surplus)

Weight: Approx. 1.4 kg

Feature: Standard front plate, no user-adjustable knobs

Core Function: Precise current signal gating, summing and amplification in drive control loops. It collects multiple current feedback signals, performs gating logic and summing, then outputs a conditioned current signal to the drive regulator for current limiting, overload protection and loop stabilization.

Positioning: Key current-loop processing board for Reliance DC/spindle drives, ensuring stable and safe current regulation under varying loads.

Signal Type: Multi-channel analog current signals

Input: ±5VDC / 0–10VDC current feedback

Output: 0–10VDC standardized current signal

Isolation Voltage: 500VDC (I/O isolation)

Operating Temperature: 0°C ~ +55°C

Storage Temperature: -40°C ~ +85°C

Protection: Overcurrent, short-circuit, EMI filtering

Drive main control rack (Cardpack series)

Shielded current signal cables
