Position Controller Elgo P85, P87, P88 Series
The single-axis controller of the Elgo P8511 series will be applicable to easy standard positioning tasks. An important feature is primary the easy structured function menu. It allows, quickly and comfortable, to set the target value and if necessary, a specific quantity of desired pieces in the batch counter window.
Target value, actual value, and quantity will be displayed on the front panel. All values and parameters can be programmed via a numeric keypad on the front. Additional keys start or stops the positioning procedure. Position Controller P8721 is identical to Elgo P8511 with an additional program memory of 200 different lines. Position Controller P8822 is a 2 axes controller and fulfills except for few restrictions the whole functional range of Elgo P8721.
Three different kinds of output signals are available for the positioning:
- Digital transistor outputs for frequency inverters
- Potential free shutter relays for pole changing brake motors
- PID-Analog output* for servo systems( *in preparation for P8822)
A 24 VDC- or 115 / 230 VAC-power pack is integrated into the unit. An optional serial interface allows data transmission and communication with a superior system.
