611T / 612 T

Key Features:

These unit is designed tp receive DC current or voltage input signals, provide isolation, and output proportional DC current or voltage signals. With support for universal DC I/O rangesIt is considered ideal for panel shops and end-users that require a high-density signal conditioner that can cover a broad range of measurement applications.

• Universal DC input and output ranges offer flexibility to fit many applications.
• Auto-configuration and self-ranging technologies speed installation without pots, switches, jumpers, or software.
• Optical isolation eliminates ground loops, reduces noise, and blocks transient signals.
• Push-button calibration simplifies field adjustments for faster and easier maintenance.
• Configuration lockout safety feature prevents tampering and accidental changes.
• Reverse-acting output capability enables inverse proportional control signals.
• Each input channel can drive two outputs (a voltage and a current output signal).
• Dual channel model saves space and reduces equipment costs.
• High-resolution sigma-delta A/D converters deliver superior accuracy for reliable measurements.
• Operating temperature range: -25 to 70°C (-13 to 158°F)
