  IP65 (see BS EN 60534-1 1998). 2.2 Electrical safety requirements The SP500 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.

  3. Technical information 3.1 Description The SP500 smart 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.

  4.2 Retransmission and travel switches option board An option board can be fitted in the positioner to add valve position retransmission functionality and software travel switches functionality. The board generates a 4-20 mA current signal which represents the actual valve position. Moreover 2 output terminals are available to be configured as software travel switches.

  4.3 External power supply option board The SP500 can host an option board for 24 V power supply. It’s a 4 wiring diagram: 2 wires for current loop and 2 wires for power supply through a 24 V external voltage. This reduces dramatically the voltage drop on the current loop. The drop is 7 V when the unit is powered by the loop (2 wires), it falls to 1 V when the 4 wires configuration is used.
