The Sporlan IB series Interface Boards are designed to translate a

0-10V or 4-20mA signal from an externally supplier controller into

a proportional valve position. This signal can correlate to pressure,

temperature, superheat or any other system variable that is being

controlled by an electric valve. This is the most straightforward

implementation of Sporlan SER or CDS valves using third party

controllers, without the setup and qualication required to ensure

reliable valve response. The 3” (76.2 mm)

square board can be mounted using non-

metallic standoffs, or with the supplied

snap-track.

For more information on Sporlan Interface

Boards, please refer to Bulletin 100-50-2.

Sporlan offers a variety of standalone electric valve controls, each

targeted at precise control of a refrigeration or air conditioning sys-

tem parameter. Utilizing unique control algorithms, the Kelvin II

Series of controls features exibility for a variety of applications, and

can be paired with the proper Sporlan subcritical CO

Electric Valve

to meet the system requirements. The controls also feature RS-485

communications to enable remote monitoring, or to tie into a higher

level system controller.

For more information on Sporlan Kelvin II Series of controls, please

refer to Bulletin 100-50-5, or the I/O Manuals in the 100-50-5 series.

The Sporlan SMA-12 (Stepper Motor Actuator) is

a service tool designed to help diagnose systems

with Electric Valves by verifying proper opera-

tion of the stepper motor. The unit is powered

by two 9V alkaline batteries, and will power any

SER or CDS 12VDC bipolar stepper motor valve.

The step rate is selectable at 1, 50, 100 or 200

steps per second, and will stroke the valve in both

the opening and closing directions. Red LEDs

indicate continuity of the motor windings and

battery power, and binding posts are provided for quick connection

Sporlan PSK electronic control-

lers manage low and medium tem-

perature self contained refrigeration

units by controlling compressors,

defrost, lights and fans. There are several models to choose from,

ranging from simple logic and wiring (for base compressor and

defrost control) to models with multiple I/O and evaporator fan man-

agement (for complex compressor, defrost and fan control).

For more information on Sporlan PSK Refrigeration Controllers,

please refer to Form 100-359, or the I/O Manuals in the 100-50-6

series.

of valve cables. In the event of a controller failure, the SMA-12 can

be used to manually position a valve to maintain performance until

service can be completed. The SMA-12 is the basic troubleshooting

tool for Electric Valve operated systems.
