New dual-channel DC voltage/ current I/O transmitters feature auto-configuration and self-ranging abilities. 

DC-powered units deliver high-performance signal conversion/isolation and feature intelligent configuration that eliminates pots, switches, jumpers, and software for faster and easier installation.

Acromag’s new transmitters receive DC current or voltage input signals, provide isolation, and output proportional DC current or voltage signals. With support for universal DC I/O ranges and self-configuring capabilities, 610T series transmitters provide a simple solution for a wide variety of isolation and signal conversion tasks. The single-channel 611T ($260) and dual-channel 612T ($350) are ideal for panel shops and end-users who require a high-density signal conditioner that can accommodate a broad range of instrumentation applications.

Installation is fast and easy with Acromag’s built-in auto-configuration feature. Using a standard calibrator, the 610T’s internal microcontroller automatically senses the input source type (voltage or current) and selects the optimum performance range for your zero and full-scale input values. To adjust your output values, simply push the up or down buttons on the front panel until you read the desired output signal on your meter. The up/down buttons help you calibrate for normal (proportional) or reverse-acting (inverse) response in seconds. After you select the desired calibration, just press the set button and your configuration settings are safely saved to nonvolatile memory.

These transmitters acccept 0 to 100mA DC and ±100V DC input signals and supply 0 to 20mA DC or 0 to 10V DC outputs with full range capability. An optional external sensor adds 0 to 20 amps AC input support. For convenience, the 610T operates from a 10 to 36V DC power supply.

Both models provide high-voltage isolation between the input, output and power (3-way). On dual channel units, each channel operates independently, with inputs isolated from each other, to prevent interaction between channels.

For easy troubleshooting, each channel has diagnostic LEDs to identify input over/under range conditions. An additional status LED indicates the unit is operating properly or that the front panel pushbutton lockout feature has been invoked.

A long list of special features include the following:

• 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.
