| The SPC-704 is an
adjustable controller with 4 setpoints. The 4 setpoints
are independently adjusted, each having a Form C relay
output. This controller can be used with any sensor or
device that produces 0-20mA, 4-20mA, 0-10V, or 2-10V analogue
output. The SPC-704 will work with all Migatron analogue
output sensors. Besides the 4 relay outputs, there is
one 0-10V analogue output. This can be used to drive a
meter or other analogue drive controls. This analogue
output can also feed a second SPC-704 to produce additional
outputs. The SPC-704 also provides 24 VDC excitation power
at 150 mA to drive input sensors. The SPC-704 has a signal
averaging potentiometer that helps alleviate false trips
during sudden signal changes. |

Mechanically, the
SPC-704 is made out of sturdy (UL 94) approved materials.
The controller is DIN rail mountable. The terminal blocks
are removable for easy wiring. There are easy to view
bright LEDs that show the relay status. The SPC-704 comes
in two versions, 115 VAC or 230 VAC*. If AC power
is not available both versions can also be powered by
24 VDC. The relay outputs can handle up to 3 amps. |
