Supported Applications
The Omega OME-DB-24PR and OME-DB-24PRD series are 24-channel power relay output boards designed for I/O control applications. These daughter boards interface with compatible data acquisition systems to drive external loads, including configurations requiring Form C (change-over) or Form A (normally open) switching.
Documented compatibility includes use as an expansion board for OME-PIO-D24, OME-PIO-D48, OME-PIO-D96, and OME-PIO-D144 systems. The series is also compatible with other OPTO-22 style boards.
Operating Conditions & Performance
The relay output board operates within an ambient temperature range of 0 to 60°C (32 to 140°F) and a storage temperature range of -20 to 70°C (-4 to 158°F). Humidity ratings are specified as 5 to 90% RH non-condensing.
Performance specifications for the relay outputs include:
- Nominal Load: 50 A/250 Vac, 5 A/30 Vdc
- Maximum Switching Power: 0.1 HP
- Maximum Switching Voltage: 270 Vac, 150 Vdc
- Maximum Switching Current: 5 A
- Mechanical Life Expectancy: 2 x 10^7 operations
- Electrical Life Expectancy: 3 x 10^5 operations
- Time Value (Response): 10 ms
- Control Logic: Input TTL high (+5V) activates the relay
The board includes varistors for surge protection. Power consumption is rated at a maximum of 24 Vdc @ 0.8 A and 5 Vdc @ 0.2 A.
Configuration Options
The series offers configurable options regarding voltage, connector type, mounting style, and included cabling:
- Voltage Versions: Available in 12 Vdc or 24 Vdc external power supply configurations.
- Connector Types:
- OME-DB-24PR models utilize a 50-pin header and include a 1.5 m (5') 50-pin flat cable; they also support connection via a 20-pin connector for specific relay groups.
- OME-DB-24PRD models feature a 37-pin D-sub connector and include a 1 m 37-pin D-sub connector cable.
- Mounting Options: Models are available with optional DIN-rail mounting kits (e.g., OME-DB-24PR/24/DIN, OME-DB-24PRD/12/DIN).
- Cable Accessories: Additional cables include 20-pin flat cables in 1 m and 2 m lengths; 50-pin flat cable (1.5 m); and 37-pin male-male D-sub connector cables in 1 m and 2 m lengths.
- Field Wiring: Screw terminals are provided for field wiring connections.
Key Product Differences
The primary distinction between the two model families is the interface connector. The OME-DB-24PR series uses a 50-pin header with an included flat cable, while the OME-DB-24PRD series utilizes a 37-pin D-sub connector.
Within each family, variations are defined by:
- Voltage Rating: Suffixes or model codes indicate either 12 Vdc or 24 Vdc operation (e.g., OME-DB-24PR/12 vs. OME-DB-24PR/24).
- Included Mounting Hardware: Models with the "/DIN" suffix include a DIN-rail mounting kit, whereas standard models are panel mount only.
The physical dimensions for all boards in this series are 210 H x 130 mm W (8.3 x 5.1"). The OME-DB-24PRD is noted as being shown smaller than actual size in some documentation illustrations.
