Input Power Minimum =+14 VDC to m30 VDC @ less than 5
Watts
If a transducer is connected to the 153/1253, its power can be
supplied by the same external supply used by the 153/1253,
or by a separate external supply.
Outputs Opto-coupled Limit Switch (L.S.)
One for Open, one for Close. 30 V maximum, 10 mA
maximum
Power Loss Unit saves calibration constants and valve position
Pressure Input Signal 0 to +10 Volts DC (normally)
Can be calibrated to any full scale voltage from 1 to 10 Volts
RS-232 Bi-directional communication
Input - set point and learn commands (in 0.1% increments)
Output - (on request) actual position, pressure (in 0.1%
increments)
