Temperature controller NR 631 I / L • Compact proportional controller • Adjustable p- control area • TC- cable breakage detection • Stable plastic casing • Floating alarm-contact (option) • Also available with Schuko-connector (631 L ) The NL631I temperature controller is a Set-p°int handy and inexpensive possibility to control The set-point temperature can be adjusted small moulds, heating elements or -plates, with a k^ob and a linear scale between 0 radiators or basins in an optimal way. and 500°C ■ This controller has a proportional characteristic with zero-voltage switching in solid-state technology. The output is suitable for heating loads up to 1,8 kW / 8A with 230V @ 50Hz. For individual adaptation, the proportional area can be set between 0 and 20K. The TC connection is controlled, in case of a breakage, the safeguard relay switches off the heating and can be re-activated only if the failure is removed. Process high / low alarm (option) The process-high / low temperature limits can be set between +/-1 ... +/-15K . Exceeding of this limit is shown by a red LED, at the same time, a mechanical relay switches-over.
