Product Description
The 985-047 Actuator Commissioning Tool provides
a portable instrument for exercising, calibrating, and
testing resistive, proportional (voltage/current),
floating, and on/off actuators. LED display shows
feedback voltages or output. LEDs indicate
operating mode selection and auxiliary switch
contact closure. The Commissioning Tool combines
accurate and reliable technology in a user-friendly,
yet economical package.
The Commissioning Tool saves on installation time
and is compatible with all Siemens actuators and
most competitors’ models. A plug-in transformer or
24 Vac power supply input enables the
Commissioning Tool to output resistance,
AC voltage, DC voltage, and current for controlling
an actuator. It requires no controller hook-up, which
makes equipment calibration, setup, and adjustment
a quick and easy process.
