The Otis Instruments OI-7440 ProSafe 4x4 Controller is a wired monitor that supports up to four individual 4-20 mA wired sensor assemblies. Four relays can be individually set up to the full scale of the channel and may be set to either latching or non-latching. Compatible with any wired device with a 4-20 mA output, allowing more than just gas detection to be displayed and monitored, which will lead to a safer working environment.
