Standard device reads voltages from 0V - 150V DC (other ranges on request)


0 RELAY

This device is used to display DC voltage.
Maximum & Minimum values are logged for 24 hours (updated every 60 min).
Use the “ScAL” parameter for calibration purposes, or to change the number of decimal places displayed (see notes).
Other features include adjust able signal damping & all settings may be locked & code protected to avoid changes from being made by unauthorised personnel.



ADDITIONAL FEATURES INCLUDE:

  • adjustable RESOLUTION by adjusting the position of the decimal point and scale
  • adjustable HYSTERESIS (DIFFERENTIAL)
  • START-UP DELAY: allows the current to stabalize at startup before monitoring starts
  • REACTION DELAY: prevent tripping for a pre-set time period
  • LATCH facility: to force manual reset after fault
  • LATCH can be enabled / disabled for each relay independantly (used when one relay is alarm relay)
  • independantly invert relay action, ie close while in fault condition
  • keypad lock with code
