654T

Key Features:

This unit is designed with dual DC input voltage to 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.

• DIP switch-configuration simplifies installation without analog pots, jumpers, or software.
• Isolation eliminates ground loops, reduces noise, and blocks transient signals.
• One-step calibration with increase/decrease toggle switches simplifies field adjustments for faster and easier maintenance.
• Automatic self-calibration compensates for temperature effects and component aging to deliver maintenance-free operation.
• Configuration lockout safety feature helps prevent tampering and accidental calibration changes.
• Reverse-acting output capability enables inverse proportional control signals.
• Dual channel model saves space and reduces equipment costs.
• High-resolution 16-bit sigma-delta A/D converters deliver superior accuracy for more reliable measurements.
• Built-in transient voltage suppressors protect circuitry from electrical interference.
• Operating temperature range: -25 to 75°C (-13 to 167°C)
