P44-VMD1-T(0-10)

1 RELAY

This device is used to display and monitor 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, adjustable start-up and reaction delays, the ability to swap the relay’s functionality and a latch facility.
All settings may be locked & code protected to avoid changes from being made by unauthorised personnel.

incl 4-20mA (or 0-10V) retransmit

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
