TA-MC Actuators
Actuators High performance proportional actuators
IMI TA / Control valves / TA-MC Actuators
TA-MC Actuators High performance proportional actuators with automatic stroke adaptation which provide accurate modulating or 3-point control when used together with combined control and balancing valves – both with or without integrated Δp controller – as well as stand-alone 2-way and 3-way control valves from IMI Hydronic Engineering.
Key features >> Easy commissioning
Automatic measurement and adaptation to the valve lift as well as loaddependent end position switch-off which helps to reduce commissioning time and protect the valve and actuator from overloading.
>> Easy troubleshooting
Protected hand drive for a safe manual operation which enables easy troubleshooting.
2
>> Ease of service
The actuator housing cover is easy to remove (without screws). Parameters can be easily changed on site without using a Laptop.

Supply voltage Control signal for extenting the actuator spindle Control signal for retracting the actuator spindle Response signal during “manual” mode depending on the supply voltage: supply 24VAC: R = 24VAC max. 100mA supply 24VDC: R = 24VDC max. 100mA supply 115VAC: R = 24VDC max. 35mA Connection of a potential free contact (e.g. for frost protection) - bridged if not used Input signal continuous mode Output signal continuous mode Zero potential of signals X, Y and R - When the zero potentials of signals X, Y and R are identical to the zero potential of the supply voltage it is possible to bridge terminals N1 and N2. - If you run the actuator in continuous mode at 115 V you will have to connect N2. - If you run the actuator in three-point mode at 115 V you will have to connect N2 if you wish to use X or R at the same time.

N2 Zero potential of the “X”, “Y” and “R” signals. - If the actuators in 115 VAC design are to be triggered on the “continuous” mode of operation, i.e. by analogue signal “Y”, the connection of N2 (zero potential of the controller) is absolutely necessary. - For actuators in 115 VAC design, the connection N2 in the “3-position” mode of operation is only necessary if “X” and/or “R” are to be use by the actuator. - If the zero potentials of the signals X, Y and R are identical with the zero potential of the supply voltage, a bridge can be laid between N1 and N2 in order to save an additional lead to N2.
Manual operation Handwheel with automatic switch-off of the actuator. Position indication Indicators on the mounting rig. Settings Automatic detection of broken control wire (for 2-10V / 4-20 mA only). Automatic detection of blocked valve.

Supply voltage Control signal for extenting the actuator spindle Control signal for retracting the actuator spindle Response signal during “manual” mode depending on the supply voltage: supply 24VAC: R = 24VAC max. 100mA supply 24VDC: R = 24VDC max. 100mA supply 115VAC: R = 24VDC max. 35mA Connection of a potential free contact (e.g. for frost protection) - bridged if not used Input signal continuous mode Output signal continuous mode Zero potential of signals X, Y and R - When the zero potentials of signals X, Y and R are identical to the zero potential of the supply voltage it is possible to bridge terminals N1 and N2. - If you run the actuator in continuous mode at 115 V you will have to connect N2. - If you run the actuator in three-point mode at 115 V you will have to connect N2 if you wish to use X or R at the same time.

N2 Zero potential of the “X”, “Y” and “R” signals. - If the actuators in 115 VAC design are to be triggered on the “continuous” mode of operation, i.e. by analogue signal “Y”, the connection of N2 (zero potential of the controller) is absolutely necessary. - For actuators in 115 VAC design the connection N2 in the “3-position” mode of operation is only necessary if “X” and/or “R” are to be use by the actuator. - If the zero potentials of the signals X, Y and R are identical with the zero potential of the supply voltage, a bridge can be laid between N1 and N2 in order to save an additional lead to N2.
Manual operation Handwheel with automatic switch-off of the actuator. Position indication Indicators on the mounting rig. Settings Automatic detection of broken control wire (for 2-10V / 4-20 mA only). Automatic detection of blocked valve.
