The M3506 Current Controller is designed to output a regulated DC current into various seal wire impedances, with consistent rise and fall times. The AC power feed supply can range from 10VAC to 130VAC. The controller can achieve better than 1% regulation with a 20% change in load or line. The current can be controlled by an external 5k reference pot which is tailored with a limit pot, or by a 4-20mA remote control loop. The enable input uses its own isolated voltage, and can be enabled with a dry contact, or a 12V signal. No control signals should ever be earth grounded. A 0-10mA output is available for reading the current. This output is held for 2 seconds after the current is gone so that the meter will read steady while unit is in production.
