Digitally configurable proportional push actuator with electronic fail-safe function – 160/200 N

Digitally configurable fail-safe actuators with or without change-over, and a wide range of setup options provide extensive flexibility for on-site parameter adaptation. Fully programmable binary input, relay and adjustable max. stroke of the valve bring new opportunities for advanced hydronic control and balancing.

Key features

Fully configurable fail-safe

Setting of stroke position (extended, retracted or intermediate position) and delay feature for entering/leaving fail-safe mode for a reliable and optimal fail-safe function.

Convenient, reliable setup

Fully customisable by smartphone via Bluetooth using a TA-Dongle.

Fully configurable

More than 200 setup options allow input and output signals, binary input, relay, characteristics and many other parameters to be configured.

Easy diagnostics

Tracks the last 10 errors to allow system faults to be found quickly and health check of fail-safe function.

Quick copying of settings

Setup configuration can be copied quickly from the TA-Dongle to identical TA-Slider actuators.
