Pin 7 which is normally uti lized to provide power into the Alicat device can
be used to provide power to your external sensor. Please make sure that
the power you are providing to the device is compati ble with the power
your sensor can accept before choosing to wire power in this manner.
CAUTION! Do not connect power to pins 1 through 6 as permanent
damage can occur!
POWER AND SIGNAL CONNECTIONS
Power can be supplied to your controller through either the power jack or the 8 pin
Mini-DIN connector.
An AC to DC adapter which converts line AC power to DC voltage and current as
specifi ed below is required to use the power jack.
A 2.1mm, positi ve center, 12-30 Vdc AC/DC adapter rated for at least 250 mA is
required to use the adapter jack in a PC-Series controller.
A 2.1mm, positi ve center, 24-30 Vdc AC/DC adapter rated for at least 500 mA is
required to use the adapter jack in a PCR-Series controller.
NOTE: 4-20mA analog output requires at least 15 Vdc.
