The switching amplifier VT-SSBA1-PWM is directly mounted at the K4 connector of the valve.
It is supplied with 24 V direct voltage. If at wire 2 (enable "IN"), a high-signal is applied, the voltage profile is applied at the valve according to the functional diagram. If the enable input is switched, the status display LED is flashing "yellow".
Fast switching (V001)
As fast switching amplifier, the VT-SSBA1-PWM considerably reduces the switching time of standard directional valves in connection with 12 V solenoids.
On switching on, the solenoid is overexcited with 24 V by 100 %. Afterwards, the voltage is reduced and the required holding current is set via pulse width modulation.
The switching time table in section Technical data illustrates the assignment of the valves to the switching amplifier.
Energy saving (V002)
If 24 V standard directional valves are used, the switching amplifier considerably reduces the continuous current to save energy.
After a defined power supply time and the connected hydraulic switching of the valve, the system switches to pulse width modulation and the power is considerably reduced. This leads to a holding power under the power of a 24 V valve at 24 V supply voltage.
The table on energy saving in section Technical data illustrates the assignment of the valves to the switching amplifier.

Additional valves on request.
If the connector switching amplifier is used, the power limit may be improved. The degree of improvement depends on the respective switching symbol of the valve.
Additional information on request.
Notice:
The specified switching times correspond to the time of signaling until a pressure change of 5 %. The switching times are specified for the same power limits as documented in data sheets 23178, 23340 and 23352 and for a horizontal installation position. The use of plug-in amplifiers V001 is not possible in connection with valves with amplified spring.

The connector switching amplifier may only operated in accordance with the limits and applications defined in the data sheet. Sufficient distance to radios and mobile phones is required (>> 1 m). In case of overload or short-circuit, the output is de-energized. Before switching it on again, enable signal "IN" has to be switched at "ON" (< 3.5 V). There is no galvanic isolation between the input and output. If used as power reducer, the power in PWM operation is not sufficient for repeated switching of the valve after exceeding the power limit in switched state. In case of an error, the temperature of the valve solenoid may increase. Take external monitoring measures to ensure that the maximum admissible surface temperature of the solenoid is complied with. The VT-SSBA1-PWM is no safety-relevant part of a control system according to EN ISO 13849-1:2006. To comply with safety requirements, the following points must be observed: In case the safety function is required, the voltage supply and the enable input of the VT-SSBA1-PWM is to be switched off by a suitable switching element with appropriate reliability. If persons have to enter the danger zone with activated VT-SSBA1-PWM, additional measures for guaranteeing their safety have to be taken for the reasons specified above.
