WAV E S E R I E S WAV E T TA
NEW
Most commonly used temperature sensors and DC inputs are
accepted, and the TTA also allows the user to define specific
characteristics, so special sensor types and linearization can
easily be accommodated.
To help simplify installation and loop commissioning, test
terminals are provided to permit input and output signal
checks without removing cabling.
For linearized and/or isolated analog outputs, the user has a
choice of standard or scalable DC current and voltage ranges.
These can be set as either direct or reverse acting. The user
can also select upscale or downscale output in the event of a
sensor break or an open circuit in the input.
The WAVE TTA is a “universal” transmitter trip amplifier. It is
part of Weidmuller’s well-established WAVESERIES family of
analog signal conditioners, which are widely used in process
and factory automation applications.
The TTA provides two independently settable changeoverrelay outputs, for use as high and low level alarms or control
points.
Configuring the versatile TTA to change input and output
parameters is simple, and performed from a computer via an
interface (CBX100 USB). The necessary TTA SET software
comes free of charge with the WAVE TTA.
The WAVE TTA is an intelligent signal
• isolator
• converter
• transmitter
• linearizer
• trip amplifier
The WAVE TTA accepts voltage supply between 18 and 264 V
AC or DC.
The TTA will function accurately over a wide ambient temperature range, and over a wide supply voltage range, and with
most types of sensor inputs. For two wire current transmitters,
24 V DC power is provided. Alternatively the TTA can be a
passive input for the current source.
The TTA comes in a black WAVESERIES UL 94 V0 housing,
for mounting on TS35 DIN rail. Pluggable connectors, allow
screw or tension clamp wiring. A screwdriver-releasable front
flap gives access to the configuration interface socket.
The WAVE TTA is CE and cULus approved.
