The Deif RMC-122D is a compact and multifunctional protection relay for monitoring and protecting electrical systems from abnormal voltage, current, or operational conditions. Made for incorporation into Uni-Line PTD21 series installations, the Deif RMC-122D provides consistent protection through programmable thresholds and relay logic. With a rated supply voltage of 230V AC, the RMC-122D has a supported measurement current of 0.8A and module rating of 1.3A, which makes it perfect for medium-voltage distribution panels and generator applications. Relay B and Relay C are both configured in a de-energized default state, providing fail-safe operation. The unit is designed to withstand voltages up to 600V CAT III, with strong insulation and adherence to industrial protection requirements. With a weight of 610 grams, this relay is constructed for heavy-duty applications, ranging from gensets and substations to factory control panels.

Key Features:
1. Multi-function Protection Relay : Supports configurable protection logic for voltage, current, and system status monitoring.
2. Measurement Current : 0.8A Allows precise monitoring in control loops and relay logic applications.
3. Module Current Rating : 1.3A Ensures compatibility with industrial loads while maintaining safe operation limits.
4. Operating Voltage : 230V AC Standardized input for seamless integration into global electrical systems.
5. Fail-safe Relay Configuration : Relay B and C are normally de-energized to ensure protection under fault conditions or power loss.
6. High Voltage Tolerance : 600V CAT III Suitable for use in distribution panels with transient over-voltage protection.
7. Scale Factor : 1 (Direct Readout) Simplifies monitoring and eliminates the need for external scaling or conversion.
8. PTD21 Uni-Line Compatible : Works with Deif’s Uni-Line series for cohesive monitoring and control system architecture.
9. Robust and Compact (610 gm) : Strong enclosure for panel mounting with minimal space requirements.
10. Part Number : 600000099.20 Ensures easy identification, reordering, and compatibility tracking.
Applications:
1. Generator Protection Panels : Monitors voltage/current levels to prevent overload or underload during generator operation.
2. Transformer Monitoring : Protects transformer secondary circuits by alerting on abnormal current draw.
3. Industrial Power Distribution : Integrated into switchboards to ensure safe and stable voltage/current levels.
4. Motor Control Centers : Acts as a protective relay in motor startup, running, or fault conditions.
5. Substation Relay Panels : Provides auxiliary protection in medium-voltage substations and ring main units.
6. Marine Electrical Systems : Used in shipboard electrical panels for relay-based protection schemes.
7. Genset Control Units : Protects diesel or gas-powered generator sets from abnormal electrical conditions.
8. Manufacturing Equipment Safety : Detects faults in power feeds supplying sensitive industrial machinery.
9. SCADA-Connected Relaying : Interfaces with monitoring systems for remote fault detection and relay actuation.
10. Temporary Power Systems : Installed in mobile panels used at construction or event sites for protection and compliance.
