Performance highlights

The X005 Galvanic Isolation Amplifier is engineered for use with Althen’s intrinsically safe position sensors. It features a high-speed bandwidth of 4.7kHz (-3dB), making it ideal for dynamic measurements and servo control loops. This module supports both voltage and current output configurations and provides precise signal transmission from hazardous to safe zones.

Usage conditions

Designed for hazardous area applications, the X005 is certified to ATEX, IECEx, and UKEX standards. It supports an input power supply of 12–30 VDC and delivers a stable +5V supply to the connected sensor. The operating temperature range is -20°C to +60°C, with extended storage down to -40°C and up to +100°C.
