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
Aditional Options:
(device with -T) A 4 -20mA retransmitted signal is optically isolated from the input signal.
(device with -P) An on-board 10V DC power supply (limited to 23mA) is included to power the transducer.

 

 1 RELAY

The signal is 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.
The relay remains 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 reenergise.
Note: the relay will NOT re-energise while the latch pins are shorted. The latch pins can also be used as a reset.

 

ADDITIONAL FEATURES INCLUDE:

  • monitor for "OVER"/"UNDER" value conditions
  • independantly reverse relay(s) action (energise or de energise when fault occurs)
  • adjustable hysteresis (differential)
  • negative span values allows display to reduce in value as input increases (eg 100%=4mA, 0% = 20mA)
  • adjustable resolution, by adjusting decimal point
  • seperate upper and lower set points allows the device to be set for OVER, UNDER or WINDOW COMPARATOR monitoring
  • adjustable "START UP" delay, allows input to stabalize at power up before monitoring starts
  • adjustable "TRIP" delay (reaction delay) allows fault conditions for short period of time
  • activate the "LATCH" facility independantly for each relay (use one relay to control, and another to latch alarm conditions)
  • adjustable calibration facility allows the user to improve overall system accuracy (compensate for transducer inaccuracy)
  • keypad lock with 4-digit code
  • re transmit the signal (or any part thereof) as 4-20mA, set re transmit offset and span to any value within the display scale.
