D3-CMD1-T

1 RELAY

The 50mV DC input signal is displayed as the current through the shunt with up to 3 decimal places.
The relay may be used for over and / or under protection.
Maximum & Minimum values are logged for 24 hours (updated every 60 min).
Other features include relay latch, adjustable signal damping, adjustable start-up and reaction delays, the ability to swap the relay’s functionality.
All settings may be locked & code protected to avoid changes from being made by unauthorised personnel.

ADDITIONAL FEATURES INCLUDE:

• adjustable scale & resolution
• 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
