CARLO GAVAZZI DCP01DM69 Product Description

Overview

CARLO GAVAZZI DCP01DM69 is a DPC01 series DIN-rail mounted true RMS three-phase mains monitoring relay. The Carlo Gavazzi datasheet and DigiKey record identify it for phase loss, phase sequence, voltage asymmetry, tolerance, overvoltage and undervoltage monitoring on a 600 to 690 V AC three-phase supply. It is an existing-panel mains monitoring or protection relay spare for industrial motor, generator, switchboard or UPS installations.

Features

The DPC01DM69 power supply is provided by the monitored phases L1, L2 and L3. Its voltage range is 600 to 690 V L-L AC ±15 percent, corresponding to 510 to 793 V in the public DigiKey trip range. The relay monitors phase sequence, phase loss, asymmetry, tolerance, undervoltage and overvoltage. It works on 3P or 3P+N systems; in 3P it measures V_L12, V_L23 and V_L31, while in 3P+N it measures V_L1N, V_L2N and V_L3N.

The DPC01 series provides two changeover relay outputs, SPDT or 1 Form C, rated 8 A at 250 V AC per DigiKey contact rating. Public DPC01 references also list AC15 rating 2.5 A at 250 V AC. Delay on alarm is adjustable from 0.1 to 30 seconds. Two independent delay functions are provided: one for over or undervoltage alarms and one for asymmetry or tolerance alarms.

Front dials adjust overvoltage, undervoltage, asymmetry and tolerance setpoints. Undervoltage setting range is -2 to -22 percent, overvoltage 2 to 22 percent, asymmetry 2 to 22 percent, and tolerance ±2 to ±22 percent. Phase loss detection triggers when one phase is 85 percent or less of rated value, including regenerated voltage detection; restore requires all phases above 85 percent of rated plus hysteresis. Phase loss reaction time is ≤200 ms, with fixed 2 percent hysteresis.

Principle

The monitoring relay continuously measures the three supply phase voltages and compares them with the configured undervoltage, overvoltage, asymmetry, tolerance and phase-sequence conditions. If all phases are present, the sequence is correct and voltages remain within limits, the relay outputs remain in their normal operating state. Phase loss or incorrect sequence immediately de-energizes output relays 1 and 2 according to the datasheet.

Overvoltage or asymmetry triggers output 1 to turn OFF after the set alarm delay 1. Undervoltage or out-of-tolerance condition triggers output 2 to turn OFF after the set alarm delay 2. The relay contacts can be wired to an alarm indicator, PLC input, motor starter contactor enable, generator protection circuit or shutdown interlock.

Replacement should verify the three-phase system voltage, frequency, 3P or 3P+N wiring, neutral connection requirement, output contact configuration, contactor or PLC input voltage, alarm delay settings, phase sequence direction, asymmetry or tolerance thresholds, terminal numbering, DIN rail mounting and DIP-switch configuration. Because the relay protects a supply or motor branch, replacement and commissioning should follow local electrical safety, isolation and lockout procedures.

Applications

CARLO GAVAZZI DPC01DM69 is used on existing high-voltage three-phase supplies, motor control centers, generator panels, pump or fan starters, compressors, HVAC controls, process skids, switchboards, crane or hoist panels, UPS or inverter bypass panels and industrial power distribution. In legacy installations, it serves as a direct replacement mains monitoring relay spare when the supply voltage, frequency, system type, output contact rating, delays and thresholds match the original DPC01 unit.
