Product Description
The Festo ZSB-1/8-B is a pneumatic control block for two-hand start systems, designed as a Type III A two-hand control device according to ISO 13851 . This safety component prevents unintentional machine startup by requiring both hands to actuate two separate input signals simultaneously, achieving Performance Level c / Category 1 per EN ISO 13849-1 .
Key Features & Advantages:
Type III A Safety Function per ISO 13851: The control block is a certified safety component under the EU Machinery Directive 2006/42/EC . It ensures that a machine cycle can only be initiated when both hand controls are actuated within a short time window, meeting the requirements of Performance Level c / Category 1 .
Pneumatic Direct Control with Positive Overlap: Operates pneumatically with a positive overlap (搭接) of the valve spool . The output signal is generated only when both input signals are present simultaneously.
Certified ATEX Hazardous Location Use: Suitable for use in ATEX Zone 1, 2, 21, and 22 explosive atmospheres , making it ideal for environments where flammable gases or dust may be present.
Wide Operating Pressure with High Flow: Works reliably in a pressure range of 4 bar to 8 bar with a standard nominal flow rate of 50 l/min (normalized to DIN 1343) , providing sufficient capacity for most pneumatic control applications.
Robust Anodized Aluminium Construction: Housed in an anodized wrought aluminum alloy casing with a die-cast aluminum cover and NBR seals , offering durability with a corrosion resistance class (CRC) of 1 (low corrosion stress) .
