It ensures a highly accurate proportional relationship between valve travel and the value of the input electrical signal (mA), and is suitable for use with straight or angle stroke pneumatic actuators.<\/p>\n<p>Designed with a die-cast aluminum housing, this positioner offers excellent weather resistance and is suitable for outdoor installation. It supports an angular travel range of -57\u00b0 to 57\u00b0 and a straight travel range of -28\u00b0 to 28\u00b0. Users can choose whether to have a mounting kit or a gauge kit, depending on requirements, and specify the type when ordering. The unit accepts a 4-20 mA signal as a control input, has a gas supply pressure range of 1.4 to 6 bar, and supports a reaction control mode.<\/p>\n<h4>Communication and Extended Functionality<\/h4>\n<p>The SP7-1 positioner is equipped with a local communication interface (LCI) and supports \"HART\u00ae communication\" (optional HART\u00ae5 or HART\u00ae7 protocol).
