Digital Temperature Controllers - ASR400 and ASR900

The Richards model ASR400 and ASR900 micro processor temperature process controllers are very economical solutions for temperature control in your process. These instruments are also inexpensive enough that they can also be used in situations where just an indicator is required. They are accurate and have selectable inputs for all standard thermocouple Types (B, C, E, J, K, N, R, S, T & Platinel II) and Pt100 JIS three wire RTD’s. Their sizes are excellent for panel mounting of multiple instruments. The ASR400 and ASR900 are bezel mount instruments, which require no mounting screws for installation in panels. Features: √ ASR400: Up to two alarms √ ASR900: Up to three alarm √ Multi range input (TCs and RTDs) √ Two individual outputs √ Self-diagnosis function √ RS232 and RS485 communication √ Fuzzy Logic PID control √ Adjustable output range √ 4 levels of security and lock-out √ 0.2% accuracy (displayed) √ ASR900: Bar graph % output display Output options: Relay contact - SPDT 3A-240VAC SSR Voltage pulse - 20VDC-20mA Current 4-20mA Example range: Type K (Thermocouple): 0 to 1200°C ( 0 to 2192°F )
