CONTROLLER AL808
1. General Description
ALTEC
The Al808 series controller is indented for industrial temperature and process control applications. Model 808 are digital temperature controllers. The 809 are valve positioning controllers. Parameters and configuration values are set by use of the front panel keys. The PAR button selects the parameter and the up and down arrows are used to alter their value. The controller can be switched directly from automatic operation to manual by means of A/M button. Without change of the hardware the main process variable input of the instrument can be configured to suit various thermocouples and resistance thermometers,(Pt100). Recalibration is not necessary for this procedure. Signals up to 50mV can be accommodated by using input adapters in the linear input option. Linearisation is scaleable within the display range of -999 to 9999, with tenths display resolution.
