Product short description:
- DC current input
- Single/dual-channel DC-powered isolators
These units receive 4-20mA process current inputs and provide isolated 4-20mA output signals. Each channel operates independently and is isolated from the others to prevent interaction between channels.
651T, 652T: Multi-Channel, Two-Wire Isolators Description
These units receive 4-20mA process current inputs and provide isolated 4-20mA output signals. Each channel operates independently and is isolated from the others to prevent interaction between channels.
For easy troubleshooting, each unit has LEDs and diagnostic test points. Power LEDs help identify output open loop conditions. The precision 10 ohm sense resistor enables monitoring of the output signal without disturbing field wiring.

Why Do I Need Electrical Isolation? - 8500988 (Log in to view the file)Why do we need signal isolation? Acromag is in the business of signal conditioning. We manufacture circuits that amplify, isolate, filter, and convert one signal form to another. Most of these circuits also provide electrical isolation. However, added isolation has a cost. Thus, sometimes customers either question their need for isolation or fail to recognize...How to Re-transmit and Isolate 4-20mA Signals from Remotely-Mounted 3-Wire Gas Detection Sensors - 8400957Defining the Problem: Signals from 3-wire remote sensors that monitor combustible and toxic gases are typically transmitted directly to the remote gas monitor or controller. However, in some cases, it’s desirable to send the signal to more than one destination. This can either be accomplished by re-transmitting the existing signal to additional locations; or by...How to Select a 4-20mA Isolator - 8400850 (Log in to view the file)Click here to download How to Select a 4-20mA Isolator Introduction Acromag manufactures a variety of isolators to provide a cost effective solution for many applications. The main reasons for using an isolator are to: eliminate bucking power supplies; protect expensive control room equipment from transient spikes; and break ground loops that may exist between...How to Use Acromag 600T Series Isolated Transmitters - 8401028Application 1 Re-transmitting a signal from a two-wire loop to a second location. Solution Use either a model 651T-0600 (single channel) or 652T-0600 (dual channel) transmitter. Application 2 Splitting a signal from a two-wire loop: two outputs for different locations. Solution Use either a 653T-0600 (single input, dual output) or 652T-0600 (dual input, dual output)... -
