Product Overview
When a control panel needs flexible relay outputs that handle both AC and DC loads, the Schneider Electric 140DRC83000C delivers. This discrete output module belongs to the Modicon Quantum automation platform and provides eight individually isolated Form C relay channels. Each channel offers one normally open and one normally closed contact, so you can wire interlock, alarm, or switching circuits without adding external relays.
The 140DRC83000C suits oil, gas, and industrial automation cabinets where mixed voltages and dependable switching matter. Its conformal coating resists moisture, dust, and corrosive atmospheres common in process areas.
Technical Specifications
Voltage and Load Flexibility
The module accepts 20…250 V AC, 30…150 V DC, and 5…30 V DC on its discrete outputs. That spread lets one module drive pilot lights, solenoids, and interposing relays across different circuits. Maximum load current reaches 5 A at 250 V AC resistive, while surge current handles 20 A for 10 ms capacitive loads.
Durability and Isolation
Mechanical durability is rated at 10,000,000 cycles. Electrical durability reaches 200,000 cycles at 5 A 250 V AC resistive. Isolation between channels and between channels and the bus is 1780 Vrms AC for 1 minute and 2500 V DC, protecting sensitive backplane logic from field transients. Output overvoltage protection is internal by varistor at 275 V.
Environmental Ratings
The module operates from 0 to 60 °C and stores from -40 to 85 °C. Relative humidity tolerance is 95 % without condensation, and operating altitude reaches 5000 m. It carries CE marking and complies with UL 508 and CSA C22.2 No 142. Product certifications include FM Class 1 Division 2, RINA, DNV, GL, ABS, RMRS, GOST, and C-tick.
Buyer’s Guide: Matching the 140DRC83000C to Your Panel
Before ordering, confirm your backplane has 560 mA of bus current available for this module. Check that your field wiring matches the Form C contact arrangement and that your load falls within the voltage and current windows above. The addressing requirement is 0.5 output word, so plan your I/O map accordingly.
If you are replacing a failed relay output card in a Modicon Quantum rack, verify the slot position and terminal block compatibility. The 140DRC83000C uses a standard module format and weighs 0.3 kg. Front LEDs show bus activity, external faults, and per-channel status for quick diagnostics.

Installation and Maintenance
Mount the module in a Quantum backplane slot with adequate ventilation. Keep ambient temperature within 0 to 60 °C. Inspect relay contacts periodically if switching inductive loads, and follow the manufacturer’s safety manual for all service work. The conformal coating helps extend service life in humid or contaminated areas, but do not apply solvents or attempt internal repairs.
Please verify current lifecycle status and availability with Oil AutoTech before ordering.
