In addition to Air Tank Drain Valves, Jiedeng Machinery also offers Drain Valve Controllers, serving as a manufacturer and supplier of one-stop solutions. This product series specifically comprises two main models, featuring flexible and convenient installation suitable for a wide range of vehicle types—including heavy-duty trucks, mining trucks, coaches, city buses, and semi-trailers.
The Drain Valve Controller is the intelligent control core of the pneumatic braking systems for commercial vehicles, buses, and trailers. When used in conjunction with the electrically controlled drain valve, it functions as the brain of the drainage system.
It is mainly used to control the electrically controlled drain valve, facilitating the automatic drainage of condensate water in the air reservoir, thereby preventing rusting of the pipelines and valve bodies as well as brake failure.

JD CODE: PSC-010 SIZE: 120*100*35 Installation hole: 4 - φ9 Working voltage: DC 18V - 36V Maximum control channels: 8 Fault detection: short circuit or open circuit Protection level: IP5X Operating temperature: -20℃ to 100℃ Product material: aluminum alloy Plugin model: AMP 174047-2 |
It is used as the control unit for the electrically controlled drain valve. For low-temperature environments and high-altitude areas with the risk of freezing, if the temperature monitoring function needs to be enabled, a temperature sensor must be connected. The maximum control circuit is 8. Under normal conditions, it can control up to 8 electrically controlled drain valves, but by paralleling, more drain valves can be controlled. |

JD CODE: RXPSECU-07-A1 SIZE: 120*100*28 Installation hole: 4 - φ4 Working voltage: DC 19V - 32V Max. control channels: 7 Fault detection: short circuit or open circuit Protection level: IP5X Operating temperature: -20℃ to 100℃ Product material: plastic Plug models: AMP 174045-2 and AMP 174046-2 |

The basic functions of the two intelligent drainage controllers are highly similar. Essentially, PSC-010 is an upgraded version of RXPSECU-07-A1. Both support temperature monitoring, fault detection, CAN communication, and multi-valve parallel expansion. They perform identically in conventional drainage control scenarios.
The main difference lies in the upgrade of details:
PSC-010 has upgraded the shell from plastic to aluminum alloy, which has enhanced its impact resistance and is more suitable for harsh working conditions; the interface has been merged from dual slots to a single slot, making the installation and wiring process more streamlined.
New features include working lights, flashing code lights, and fault lights, significantly improving the efficiency of fault detection, and the maximum control channel has also been upgraded to 8 channels.
The aluminum alloy casing is more durable and resistant to damage.
The single-slot design offers simple wiring.
The three indicator lights facilitate quick troubleshooting.
The 8-channel control provides greater scalability, making it suitable for various complex working conditions.
It is fully functional in one step.
It has all the core functions, meeting the basic drainage control requirements.
The plastic casing has a lower cost.
With 7 control channels, it is suitable for common scenarios and can be used stably even with a limited budget.
Both of the two intelligent drainage controllers support flexible installation:
The PSC-010 model is equipped with 4 φ9 installation holes, and the RXPSECU-07-A1 model is equipped with 4 φ4 installation holes.
They can be directly fixed with screws or quickly fixed with cable ties, and are suitable for various installation scenarios.
The installation location is recommended to be selected in areas such as the vehicle electrical compartment, the interior of the driver's cabin, which are dry, ventilated, and convenient for maintenance, avoiding areas where the chassis is prone to splashing mud and high-temperature heat sources, and avoiding outdoor bare installation to ensure the stable operation of the equipment.
It is mainly used in all commercial vehicle models with pneumatic braking systems, such as heavy trucks, mining trucks, buses, city buses, and semi-trailers.
It automatically controls the heating of the drainage valve and discharges the condensate water from the air reservoir, preventing pipeline rusting, preventing ice blockages in winter, and ensuring the safety of the brakes.
The three indicator lights are the working light, the flashing code light, and the fault light. In a normal working state, the working light remains constantly on; if there is a fault, the fault light remains constantly on while the flashing code light flashes. Based on the flashing pattern of the flashing code light, you can initially determine the cause of the fault.

The intelligent drainage controller features flexible control modes, allowing for the selection of appropriate solutions based on actual requirements:
If connected to the CAN bus, it can flexibly configure various drainage, heating, and protection logic based on parameters such as vehicle pressure and speed, adapting to complex working conditions.
The default control logic is the commonly used mode for customers. It does not require connection to the CAN bus and can operate normally upon power-on.
The operation is convenient and no additional debugging is needed. It can meet most of the routine usage scenarios. Specifically:
1. When the vehicle key switch is turned to the ON position, the vehicle will perform the automatic drainage function:
① t°＞3℃: Drainage occurs immediately;
② t°≤3℃: the power-on and drainage cycle will not be executed;
2. When the key switch is turned off:
① t°＞3℃:Drainage occurs immediately;
② t°≤3℃:Drainage will not be executed when the power is turned off.
3. The drainage interval time for the wet storage valves is 30 minutes, the drainage interval time for valves #2 to #8 is 2 hours, and the drainage time for each cycle is 2 seconds.
1. After powering on the ON position:
t°≤3℃:Heating control output；
t°≥5℃:Heating control has stopped the output.；
2. After powering on the ON position，t°＞3℃：Heating control is not outputting.
1. After pressing the forced drainage button, the forced drainage will be executed.；
2. When the button is released, the forced drainage will be stopped.。
