H-type Single-pole Trolley Wire
1. Used for monitoring
passive switch signal input occasions, such as emergency stop monitoring, safety door monitoring and other application scenarios
This type of product has three specifications:
TXAS1-3012 Manual/automatic optional, rising edge start, instantaneous 3NO+1NC
TXAS1-3012A Manual falling edge start, instantaneous 3NO+1NC
TXAS1-2202 Manual/automatic optional, rising edge start, instantaneous 2NO+delay (3~15 seconds) 2NO
2. Used for monitoring
active switch signal input occasions, such as light curtain monitoring application scenarios
This type of product has three specifications:
All are manual/automatic optional, rising edge start, instantaneous 3NO+1NC
TXAS1-3012N is suitable for scenarios where the dual output signals of the light curtain are low level
TXAS1-3012P is suitable for scenarios where the dual output signals of the light curtain are high level
TXAS1-3012NP is suitable for scenarios where one output signal of the light curtain is low level and the other output is high level
For example, machine tool industry requirements:
When the emergency stop is pressed, the power supply is disconnected instantaneously, and the controller power supply is disconnected with a delay
The process action can only be started when the safety door is closed, and the process action must be stopped when the safety door is opened
This safety requirement can be achieved by selecting TXAS1-2202+TXAS1-3012
For example, injection molding industry requirements:
When the emergency stop is pressed, the power supply is disconnected instantaneously
The mold clamping action and other process actions can only be started when the safety door is closed
The mold clamping action must be stopped when the safety door is opened.
Electrical safety must be interlocked with hydraulic safety
This safety requirement can be achieved by selecting two TXAS1-3012 units
For example, automatic assembly line requirements:
When the emergency stop is pressed, the power supply is disconnected instantaneously
The process action can only be started when the light curtain is normally transparent,
If the light curtain is blocked, the process action must stop instantaneously
This safety requirement can be achieved by selecting TXAS1-3012+TXAS1-3012N
3. Used for monitoring
short circuit signal input occasions, such as safety edge and safety mat monitoring
This type of product has one specification:
TXAS1-3012B Manual/automatic optional, rising edge start, instantaneous 3NO+1NC, supports four-wire input and two-wire input modes
4. Used for monitoring
time difference signal input occasions, such as two-hand start monitoring
This type of product has one specification:
TXAS1-3012S Rising edge start, instantaneous 3NO+1NC
The above products are all dual-channel products. With appropriate wiring,
they can all achieve the highest safety level required by safety standards such as EN954 and ISO13849. The combined use of the above products can meet the different safety design needs of mechanical equipment in different industries:
