2-RELAY PROCESS 0-10V SIGNAL INDICATOR / MONITOR / WINDOW COMPARATOR OVER / UNDER PROTECTION with 4-20mA re-transmit
The input signal is converted and displayed as real-world values with up to 3 decimal places.
Maximum & Minimum values are logged for 24 hours (updated every 60 min).
By setting the Span to a negative value, the device can be used as an inverter, generating a decreasing output signal as the input increases.
Other features include user programmable signal damping & all settings may be locked & code protected to avoid changes from being made by unauthorised personnel
The input signal is converted and displayed as real-world values with up to 3 decimal places (eg 0-100.0°C ,not 4 -20mA). The 4 -20mA re-transmitted signal is optically isolated from the input signal.
The relays remain energised while the input signal is between the upper and lower set points.
Once de-energised, the signal must change in the opposite direction by the hysteresis amount before the relay will re-energise.
Shorting the latch pins, forces the relay to remain de-energised after a fault condition (until the short is removed).
The relay action may be swapped to energise when the setpoint is reached.
The signal recieved is converted and displayed as ‘real world’ values. (eg 0-100 °C ,not 4 -20mA).
By setting the span to a negative value, the display will indicate lower values as the input rises.
