OVERVIEW
The GMW 5972 Magnet Control system acts as controller,
interlock and DAQ for GMW Electromagnet Systems. A
complete system typically consists of a DC magnet power
supply, the 5972 Magnet Control, a Senis Magnetic Field
Transducer, a GMW electromagnet, and computer with control
software.
The DC magnet power supply provides current directly to the
electromagnet. The Supply’s output is enabled on a closed
contact, providing protection should the interlock cable be
disconnected. A failure in either the magnet temperature or
water flow will cause the interlock relay to open, shutting
down the DC Supply’s output.
The 5972 Magnet Control is comprised of several sections:
The display and interlock control electronics, a National
Instruments USB-6351 Control with USB interface and an
auxiliary power supply all integrated into a single 19” rack
mounting chassis.
The NI USB-6351 DAQ interface provides computer control
and monitoring of the system. It provides a 16-bit analog
output (±10V) as a programming signal to the DC Supply.
The output voltage and current are monitored by two 16-bit
input channels. The magnet interlock status is also monitored
via its digital input channels. When using an optional Senis
Magnetic Field Transducer, the field is read back on a third
16-bit analog channel. An Auxiliary Analog Input connector
allows for up to five additional analog inputs with user
settable full-scale inputs from ±2V to ±10V.
