SUBAMBIENT CONTROLLERS

 


Description

The Model 900S/RS232 is a Microprocessor based controller/timer. It monitors temperature utilizing a Type J thermocouple sensor and controls bath temperature with a standard  three mode (PID) control scheme, with anti-reset windup. Numerous status and alarm functions are incorporated to monitor various system parameters. Additionally, a down-count/up-count programmable timer, with cumulative over timer and pre-warn is integrated into the system. Two solid state relay drive outputs are included for the Chiller and Heater. A relay output is provided for the Acid Pump and Timer. An RS232 link is also provided. For information on the RS232 interface, see the Communications Supplement in the manual.
