XT120

Key Features:

Designed to offer an isolated Ethernet network interface for up to eight differential current input
Channels. The Isolated differential inputs deliver better measurements, superior noise rejection, and
Eliminates the need for current loop isolators.

• Easy setup with Windows software via USB.
• Low input impendance (27 ohms) reduces loading on current loops.
• User-configurable sample averaging (1-200) on a per-channel basis.
• 10ms network updates for all 8 input channels.
• i2o peer-to-peer updates based on change-of-state and/or timed updates.
• High-resolution 16-bit Σ∆ A/D converter ensures precise, high accuracy measurements.
• High-Density 22.5mm wide package with pluggable, front-facing terminals.
• Dual Ethernet 10/100 ports (auto-negotiation) reduce switch port requirements.
• 1500V AC isolation (between I/O, power, and network ports) and surge/transient protection.
• Supports bussed/rail and redundant power.
• -40°C to +70°C wide temperature operation.
• Withstands 25g shock and 4g vibration.
• CE compliant. UL/cUL Class 1 Div 2 Zone 2 approvals.
