1 Data Sheet SS/_5 Boundless motorized valve controller no need for slidewire feedback; improves reliability Two sealed 5A control relays suitable for direct connection to the valve, reducing installation costs Universal process input with integral 2-wire transmitter power supply direct connection for any process signal Retransmission of process variable analog output for recorder or datalogger IP66/NEMA4X front face ideal for use in the harshest environments Quick code, front face or P configuration easy operation and commissioning using our Windows -based software RS485/Modbus serial communication SADA, PL or open system integration dedicated /4 DIN controller for motorized valves

2 SS/_5 The Valve Position controller is a dedicated, single loop controller designed for direct control of motorized valves. Universal input and integral transmitter power supply ensure that the has the capabilities to measure a wide range of process signals such as temperature, pressure, flow and level. Two 5A relays are fitted as standard for either direct control of the positioner or via intermediate relays plus retransmission of the process variable for connection to a recorder or datalogger. Further I/O capabilities can be added, such as an alarm relay, remote set point and digital input, to suit the application. The configuration of the is achieved by moving the security switch and entering a simple code from the front panel keys or via our P configuration package. No passwords, no input links, no complications. With IP66/NEMA4X front panel protection and superior RF immunity as standard the has been designed to control reliably in the harshest of today s industrial environments.

3 SS/_5 Applications 5. lose Open PID ontrol Boundless control of an electrically-positioned valve with a travel time between and 5s using in-built 5A relays. The gives pulsed outputs to the valve which are based on the difference in Process Variable and Set Point. The signals the direction and time of travel to the valve. The controller does not require information on the absolute regulator position but uses the PV inputs as its feedback. The deadband setting prevents the valve from hunting. OMMANDER PR25 A 324. Boiler Temperature 5. Retransmission As standard the has a 4 to 2mA retransmission output of the process variable for connection to a chart recorder, datalogger or PL. P onfiguration To make configuration of the quicker and simpler, a Windows-based configuration software package is available. The is supplied with an in-built P configurator port as standard. onfigurations can be saved and downloaded to other instruments and a printout generated. 5. Alarm Type Alarm 2 Type Alarm Hysteresis Set Point Type SP E F G H Quick ode Setting A simple 4-digit code enables all standard parameters to be set from the front face. Ramp/Soak Set Point Profiles The ramp/soak facility available on every provides for a single program, four-segment profile. This facility also includes guaranteed ramp/soak, repeat program, skip and reset features. t RS485/Modbus Fitted with an optional RS485 serial communication board, the can communicate with PLs and SADA systems using the Modbus protocol
