The Richards model ASR900HY micro processor temperature process controller is a very economical solution 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 Pt100Ώ &
KPt100Ώ three wire RTDs. Their sizes are excellent for panel mounting of multiple instruments. The ASR900HY is a bezel mount instrument,
which require no mounting screws for installation in panels.
Features: √ Fuzzy Function, PID auto tuning √ Control Outputs: Relay, SSR, & SCR √ RS485/422 communication function
Example range: Type K (Thermocouple): -200 to 1370°C (0 to 2498°F)
Digital Temperature Controller - ASR900HY
