TA-Slider 1600 Fail-safe T-2T

Digitally configurable proportional push-pull actuator with electronic fail-safe function and temperature measurement capability – 360 lbf (1600 N)

Digitally configurable fail-safe actuators with temperature

measurement capability for all control systems for all control systems

with or without change-over. To be mounted on a PIBCV for tackling

ΔT syndrome or for handling change-over based on T supply or ΔT

sign detection. Wide range of setup possibilities gives high flexibility

to adapt parameters on-site. Fully programmable binary input, relay

and adjustable max. stroke of the valve bring new opportunities for

advanced hydronic control and balancing.

Features and Benefits

Optional ΔT and temperature return limitation

Optimize the efficiency of your production units by ensuring optimal temperature regimes.

Change-over functionality

Switch between heating/cooling flows according to input signal or automatically using T supply or ΔT sign detection.

Fully configurable fail-safe

Setting of stroke position (extended,retracted or intermediate position) and delay feature for entering/leaving failsafe 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.
