  • Page 5: Safety Information

    2.2 Electrical safety requirements The SP400 is a class III product which must only be powered from Safe Extra Low Voltage (SELV) sources whether by virtue of a 4 - 20 mA control signal or from a separate power supply. Similarly all signal circuits connected to an options board must operate within the confines of SELV systems.

  • Page 6: Technical Information

    3. Technical information 3.1 Description The SP400 smar t valve positioner is loop powered from a 4 - 20 mA input signal to provide accurate adaptive positional control of pneumatic actuated linear and quarter turn valves. Precise control is maintained through valve position feedback that automatically varies the pneumatic output pressure to overcome the effects of stem friction and flow forces to maintain desired valve position.

    4. Options 4.1 Pressure gauge block An optional pressure gauge block (Figure 3) can be fitted onto the SP400 positioner which includes two pressure gauges indicating air supply pressure and output air signal pressure to the actuator. The pressure gauge block can be retrospectively fitted using 2 off M5 socket head screws. Ensure that the gauge block air connection 'O' rings are correctly located before tightening.
