Supported Applications
The Omega DRST-FR is a programmable converter designed for industrial applications. The device features a DIN rail mountable housing and is intended for use with hazardous electric voltages.
Operating Conditions & Performance
This series operates on a power supply of 24-230VDC / 24-230VAC. The device includes analog output voltage, analog output current, digital output 1 / relay 1, and digital output 2 / relay 2 capabilities.
Configuration Options
The DRST-FR series supports configurable terminal assignments for inputs, outputs, and power. The device includes status indicators labeled f_in (two instances) and error. Key configuration options include:
• Housing & Mounting: DIN rail mountable housing according to DIN 46277.
• Connections: Terminal block connections with a communication connector connected to input terminals.
• Outputs: Analog output voltage, analog output current, and two digital/relay outputs (digital output 1 / relay 1; digital output 2 / relay 2).
• Approvals & Safety: CE mark, Double insulation symbol, Ex devices approved acc. to ATEX directive.
The terminal assignments include specific functions for analog ground (Terminal 11), voltage and current outputs (Terminals 12/13), digital grounds and relay contacts (Terminals 21-24), power supply inputs (Terminals 31-33), and sensor input/supply lines (Terminals 42, 52).
Key Product Differences
The series model number guide follows the pattern DRST-FR - <Variant>, with examples including DRST-FR/A and DRST-FR/B. The device must only be connected to the programming unit Loop Link by way of the enclosed cable.
