DRSL-DC3 DIN Rail Signal Conditioner Series w/Process Input

Supported Applications

The Omega DRSL-DC3 is an isolated DIN rail signal conditioner designed for the galvanic isolation and conversion of process voltage or current signals. The series supports interfacing with SCADA systems or PLC equipment, providing surge suppression and eliminating ground loops in industrial control environments.

Operating Conditions & Performance

The DRSL-DC3 operates within an ambient temperature range of -25 to 70°C (-13 to 158°F) with a storage temperature capability from -40 to 85°C (-40 to 185°F). Humidity ratings are specified as 0 to 95% RH non-condensing. The unit delivers an accuracy of <±0.2% of span and features a response time of <7 ms (0 to 90%, 100 to 10%). It is rated for IP20 enclosure protection.

Measurement Ranges

The series supports the following input measurement ranges:

• Current: 0 to 20.5 mA, 0 to 23 mA
• Voltage: 0 to 10.25 V, 0 to 11.5 V, 0 to 5.75 V, 0 to 5 V, 1 to 5 V, 0 to 10 V, 2 to 10 V

Output Signals

Selectable output signals include:

• Current: 0 to 20.5 mA, 0 to 20 mA, 4 to 20 mA
• Voltage: 0 to 10 V, 2 to 10 V, 0 to 5 V, 1 to 5 V

Electrical Load Requirements

The load resistance specifications are:

• Current output: 23 mA/600 Ω max
• Voltage output: >10 kΩ min

Configuration Options

The DRSL-DC3 features a slimline housing with overall dimensions of 113 H x 6.1 W x 115 mm D (4.4 x 0.24 x 4.5"). The unit weighs approximately 70 g (0.15 lb). Signal ranges are selectable via DIP switches, and the device mounts to a DIN rail without an air gap using screw terminals.

Power Supply

The series requires a power supply of 16.8 to 31.2 Vdc provided via Power Rail or Connectors (terminals 7-8).

Accessories and Options

Available accessories for the DRSL-DC3 include:

• DRSL-PWR-RAIL: Power rail with cover, two end covers (one right hand, one left hand), 1 m (3.3') length.
• DRSL-PCU: Power connector unit providing 24 Vdc/2.5 A output to the power rail.
• DRSL-MOD-STOP: Module stop screwed onto the power rail to support and hold mounted devices.

Certifications and Warranty

The series carries CE, UL US, and RoHS certifications. A 1 YEAR WARRANTY is provided with the unit.

Key Product Differences

The DRSL-DC3 model represents an isolated DIN rail signal conditioner within this series. The primary variation across the product line involves the selectable input/output ranges configured via DIP switches to match specific process voltage or current signals, rather than distinct physical housing variants.
