This part is is exactly the same part as the SSD Drives / Eurotherm part number: 690PG/1800/400/0011/UK/0/0/0/SHTTL/0/115/0 . Parker changed the naming scheme after they acquired SSD Drives / Eurotherm. It may also be referred to by other brands (including RS, Newlec etc.) as 690PG-1800-400-0011-UK-0-0-0-SHTTL-0-115-0 .
There are several communication options available (see options below) which modify the base part number to:

The AC690plusseries is a single range of AC drives designed to meet the requirements of all variable speed applications from simple single motor speed control through to the most sophisticated integrated multi-drive systems. The heart of the AC690plus is a highly advanced 32-bit microprocessor based motor control model. This provides an exceptional dynamic performance platform to which can be added a host of communications and control options, enabling you to tailor the drives to meet your exact requirements.
The AC690plus can be user configured for 3 different modes of operation :
Open-loop (volts/frequency) control - This mode is ideal for basic motor speed control, or multiple motors driven in parallel. The quick set-up menu and plain language display ensures the quickest and easiest, trouble free start up.
High starting torque and tight speed regulation is provided by a sophisticated MRAS (Model Reference Adaptive System) motor control strategy. MRAS provides accurate speed simulation (without the need for any speed measuring transducer) by continually modeling the motor.
Closed-loop vector control - Full closed-loop flux vector performance can be achieved with the AC690plus by simply adding an encoder feedback technology box.
This provides 100% continuous full load standstill torque plus a highly dynamic speed loop (up to 45 Hz bandwidth); more than sufficient for the most demanding of applications.
