Intuitive Mercury Stepper Valve with Daughter Board Option

The Intuitive Mercury EPR Stepper Valve controller can be purchased with optional daughter boards to read suction pressure which is
then used to calculate evaporator temperature and superheat, this is used for monitoring purposes only and does not have any control or
alarm functionality.
Please note the daughter boards are a factory fit option only and must be ordered with the controller
Daughter Board Options
1 x 0-10Vdc Input & 1 x 0-10Vdc Output board
1 x 4-20mA Input & 1 x 4-20mA Output board
1 x 0-10Vdc Input & 1 x Probe Input Expansion board
1 x 4-20mA Input & 1 x Probe Input Expansion board
Note: Only 0 – 10V or 4 – 20mA Inputs used in this application (Outputs are not used)
*Each daughter board comes with a colour coded connector as a visual indication.

Daughter Board Connection Details
