temperature monitoring, temperature window monitoring – Measuring principle for 2-wire and 3-wire sensors
configurable – Temperature monitor for 1-3 sensor circuits
– All configurations and adjustments by front-face operating – Adjustable over-, undertemperature monitoring or range
elements
– Precise adjustment with direct reading scales monitoring function
– One or two threshold values – 2 thresholds
– Hysteresis 2...20 % adjustable – Hysteresis for both thresholds (1-99 Kelvin)
– Operating temperature range -40...+60 °C – Adjustable time delay from 0-999 s affects to both thresh-
– 1 x 2 c/o or 2 x 1 c/o configurable
– Open- or closed-circuit principle configurable olds
– Short-circuit monitoring and interrupted wire detection – Storage function selectable via external signal (Y1-Y2)
– 22.5 mm (0.89 in) width – Non volatile storage of parameter settings
– LEDs for status indication – 1 n/o (for wire-break and short-circuit detection) and 2 c/o
– Multifunctional digital display
– 3 LEDs for status indication
– Open- or closed-circuit principle selectable
– 45 mm wide housing with 24 terminals
C512
– Temperature monitor for 1 sensor circuit
C513
– Temperature monitor for 1-3 sensor circuits
– In the 3-sensor version the status of the single sensors
is displayed if the temperature exceeds or falls below the
threshold. This way it can be easily determined which one
of the connected sensors has exceeded or dropped below
either one or both threshold values.
