The BT200 BRAIN Terminal is used to set, change, display and print out parameters such as tag numbers, output mode, and range for equipment that use BRAIN communications. This handheld terminal also monitors I/O values and self-check results, sets constant-current output, and allows zero adjustments. To perform these functions, it must be connected to the equipment's 4 to 20mA DC signal transmission lines or to a dedicated connector on the ESC (Signal Conditioner Communication Card) when the system is started up or maintained.
