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 -wire transmitter power supply direct connection for any process signal Retransmission of process variable analog output for recorder or datalogger IP65/NEMA front face ideal for use in dusty/wet environments Quick code or PC configuration simple to use Windows -based PC configuration package RS85/Modbus serial communication SCADA, PLC or open system integration dedicated /8 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 PC configuration package. No passwords, no input links, no complications. With IP65/NEMA front panel protection and superior RF immunity as standard the has been designed to control reliably in the harshest of today s industrial environments.

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 di dband setting prevent the valve from hunting. A A OP Retransmission As standard, the has a to ma retransmission of the process variable for connection to a chart recorder, datalogger or PLC. A A OP Alarm Type Alarm Type Alarm Hysteresis Set Point Type E F G H PC Configuration To make configuration of the quicker and simpler a WINDOWS-based configuration software is available. The is supplied with an in-built PC configurator port as standard. Configurators can be saved and downloaded to other instruments and a printout generated. Quick Code Setting A simple -digit code enables all standard parameters to be set from the front face. SP t 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. RS85/Modbus Fitted with an optional RS85 serial communication board, the can communicate with PLCs and SCADA systems using the Modbus protocol.
