New Family of Versatile Isolators Protect Process Equipment And Provide Power to Input Devices for the Value Conscious User
 Acromag's 630T Series AC/DC-powered 4-20mA loop isolators and signal splitters feature an internal excitation supply to drive up to two 2-wire transmitters or other field devices.
Acromag's new 630T series of multi-channel isolators provide an economical and space-efficient solution to eliminate ground loops, filter signal noise, and block high voltage surges. These inch-wide single/dual-channel isolators receive 4-20mA inputs and provide fully isolated 4-20mA output signals. Signal splitter models provide two identical outputs from a single input. A built-in excitation supply delivers power for 2-wire transmitters or other input loop devices to eliminate the cost of external power supplies. The isolator power requirement is very flexible, operating off either 90-250V AC or 15-36V DC with a 4-wire connection. Prices start at just $215.
ARC Research Director Wil Chin commented, "With these new products, Acromag is offering users an easy solution to a long-standing problem of equipment isolation while maintaining signal accuracy and safety in manufacturing. This new family of isolation products expands Acromag's portfolio of cost-effective I/O products to provide one-stop-shop convenience to automation professionals.”
The dual-channel models are ideal for tight budgets, compact spaces, and systems that may require spare channels for future upgrades. Built-in excitation supplies simplify wiring and save additional space. To reduce installation time, units arrive pre-calibrated, ready to snap onto a DIN-rail. And to meet safety standards, all units are designed for CE, UL/cUL Class I Division 2 Group ABCD approvals.

Question: How are 4-wire isolators, such as the new 630T series, used in typical applications?
Answer: There are many uses for the 630T isolators. The following application notes demonstate just a few uses.
Application note #1: How to isolate input and output signals to and from a controller. Also, how to use the built-in excitation supply to drive 2-wire field devices.
Application note #2: How to use a 4-wire isolator "splitter" to excite a field device and re-transmit the 4-20mA signal to two different locations.
Application note #3: How to re-transmit a 4-20mA signal to three locations.
