IMI TA-Slider 160 I/O
The IMI TA-Slider 160 I/O is a digitally configurable proportional push actuator manufactured by IMI Hydronic Engineering. Designed for precise control in heating and cooling systems, it features an expanding array of advanced capabilities through its binary input and relay configurations (hence the “I/O” designation), allowing for external triggers like open-window detection or change-over system integration.

Description
Key Specifications
- Adjusting Force: 160 N or 200 N (features automatic self-adjusting force and detection for IMI TA and IMI Heimeier valves).
- Power Supply: 24 VAC/VDC.
- Control Input Signal: Proportional 0(2)-10 VDC.
- Output Signal: 0(2)-10 VDC feedback signal.
- Max Stroke/Lift: Up to 6.9 mm.
- Control Speed: 10 s/mm.
- Ingress Protection: IP54 rated against dust and water splashing from all directions.
- Media Temperature Compatibility: Can withstand media temperatures up to 120°C.
Wiring & Terminal Terminal Block Layout
The “I/O” variant expands functionality via a dedicated set of terminal connections:
- L24 / M: Power supply 24 VAC/VDC and neutral line.
- YV: Proportional input control signal (0/2–10 VDC).
- XV: Output feedback signal (0/2–10 VDC).
- B: Connection for a potential-free contact (e.g., binary input for an open window sensor or change-over detection).
- COM / NC / NO: Common, Normally Closed, and Normally Open contacts for the built-in relay (Supports max 1A @ 30 VAC/VDC resistive loads).
Digital Configuration & Smart Features
- Smartphone Configuration: Rather than setting physical DIP switches, parameters are adjusted digitally using a smartphone via the HyTune app (available on iOS and Android) by connecting a plug-in TA-Dongle to the actuator’s micro-USB port.
- Binary Input Parameters: When the binary circuit (Terminal B) is opened or triggered, the actuator can be programmed to drive to a safe position, switch to an alternate stroke limitation setting, or open completely for system flushing.
- Built-in Diagnostics: Features diagnostic capabilities, an error memory, valve blockage protection, and an LED indicator that flashes distinct colors (like violet pulses for errors) to troubleshoot on-site issues.
