Single and Multi-Channel Signal Conditioners

650T Series: Isolated two-wire transmitters split a single 4-20mA input signal into two identical process current outputs.
Acromag’s 650T series transmitters provide low-cost isolation for process current loops. These loop-powered transmitters receive 4-20mA inputs and provide isolated 4-20mA output signals.
Three models are available offering a choice of single channel (Model 651T), dual channel (652T), and a signal splitter (653T) units. The 653T provides two outputs from a single input signal.

670T Series: Quad-channel two-wire transmitters add isolation to 4-20mA process loops.
Multi-channel 670T isolated transmitters inexpensively break ground loops, reduce noise, and block high-voltage transients when interfacing field devices to a PLC, DCS, or other control system.
These loop-powered transmitters receive 4-20mA inputs and provide isolated 4-20mA output signals. Each channel operates independently and is isolated from the others to prevent interaction between channels.
Three models are available offering a choice of single channel (Model 671T), dual channel (672T), and quad channel (674T) units, each only one inch wide and ready for DIN rail mounting.
