PR 2279B2D PR Electronics 24VDC 20mA Isolation Amplifier

Description

PR Electronics PR 2279B2D features a 0.5 to 250 VRMS input range, 0 to 20 mA output, and 3-port galvanic separation. The unit utilizes microprocessor technology for precise gain and zero offset selection while maintaining pure analogue signal processing. Structural and operational characteristics include an internal 1 Ω shunt for direct current measurements up to 1 ARMS, a 1.5 s time suppression, and a standard 24 VDC supply requirement. The hardware is engineered with internal DIP-switches for programmable input and output ranges, ensuring robust performance across a -20 to 60 °C operating temperature range.
