New ACR4380 octal-socket transmitter saves up to 20% over competitive DC-to-DC isolator/converters. 

Industry-standard, 8-pin plug-in transmitter delivers superior performance at a lower cost to provide a drop-in replacement for a broad range of isolation and signal conditioning applications.

Acromag’s new ACR4380 receives DC current or voltage input signals, provides isolation, and outputs proportional DC current or voltage signals. Advanced S-D A/D converters and microcontroller technology deliver superior performance and simplify maintenance. Plus, industry-standard octal-pin sockets allow for "drop-in" compatibility with competing units. Prices start at just $275 with 24-hour delivery from stock.

With support for universal DC I/O ranges and AC/DC power, ACR4380 transmitters provide a solution for a wide variety of isolation and signal conversion tasks. One model accepts 0 to 100mA DC, -100 to +100V DC, and 0 to 20 amps AC (with optional sensor) input signals, and then provides proportional 0 to 20mA or 0 to 10V DC outputs. And, the unit can be driven with either a 22 to 60V DC or 80 to 130V AC power supply. The ACR4380 is ideal for panel shops and end-users who require a signal conditioner that can accommodate a broad range of instrumentation applications.

Installation is fast and easy with Acromag’s built-in self-ranging feature. A single switch setting quickly selects between DC voltage or current input. Next, using your standard calibrator, the ACR4380’s internal microcontroller automatically selects the optimum performance range for your zero and full-scale input values. To adjust the output signal 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 quickly calibrate a normal (proportional) or reverse-acting (inverse) response. Press the set button and your configuration settings are stored in nonvolatile memory.

For easy troubleshooting, the top panel has diagnostic LEDs to identify input over/under range conditions. An additional status LED indicates that the front panel push-button lockout security feature has been invoked.
