Description:
This device is used to display and monitor DC voltage. Maximum & Minimum values are logged for 24 hours (updated every 60 min).
The relay(s) may be used for over and / or under protection. The latch facility may be de-activated for one or both the relays
allowing one relay to be used for control (not latched), and the other as a latched alarm. 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. All settings may be locked & code protected
to avoid changes from being made by unauthorised personnel.
0 RELAY
This device is used to display DC voltage.
1 RELAY
The voltage applied is displayed according to the scale specified. 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 re-energise. The relay’s action may be swapped to energise when the setpoint is reached. Note: the relay
will NOT re-energise while the latch pins are shorted. The latch pins can also be used as a reset.
2 RELAY
The voltage applied is displayed according to the scale specified. 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. Either relay’s action may be swapped to energise when the setpoint is reached. Note: the
relay will NOT re-energise while the latch pins are shorted. The latch pins can also be used as a reset.
Adjustable parameters:
Please note: Depending on the model of the device purchased, some of the parameters listed below may not be available
· Upper limit for relay 1 “Hi 1” (default: disabled)
When the input rises above this value, the relay changes state until the signal drops by the hysteresis amount
(see “HYS.1” setting)
· Lower limit for relay 1 “Lo 1” (default: disabled)
When the input drops below this value, the relay changes state until the signal rises by the hysteresis amount
(see “HYS.1” setting)

ReTransmit devices (-T)
The 4 -20mA re-transmitted signal is optically isolated from the input signal. By default the re-transmittion parameters are set so that the
output follows the full scale input.
