Description
The HIMA Z7116 is a discontinued connection cable with 16 LEDs for digital inputs (DI) and a shunt resistor, designed for use with HIMA safety control systems [1, 2, 3, 5]. Here’s a breakdown of its functionalities and what we can gather based on available information:
-
Function: It likely transmitted digital signals between safety I/O modules and a safety control unit within a HIMA safety system [1, 2, 3]. The cable’s 16 wires would correspond to 16 individual digital input channels.
-
LED Indicators (uncertain without user manual):
- The 16 LEDs on the cable might have served as visual indicators for the status of the corresponding digital input channels [1, 2, 3]. An illuminated LED likely indicated an active or high digital signal on that channel.
-
Shunt Resistor:
-
- The presence of a shunt resistor suggests the cable might have been used for interfacing with current-sinking digital input modules [2, 3]. The shunt resistor would help regulate the current flow within the circuit.
-
Safety Considerations (uncertain without user manual):
- Given its application in safety systems, the cable was likely manufactured with fire-resistant materials to minimize fire hazards within a control cabinet [2, 3].
- Proper shielding might have been implemented to minimize electromagnetic interference (EMI) that could disrupt critical safety signals [2, 3].
-
Discontinued Product: It’s important to note that the HIMA Z7116 is a discontinued product [2, 5]. This means it might not be readily available from official sources.
Applications (limited due to discontinued status):
While the Z7116 is no longer in production, it was likely used in safety control systems across various industries where safety is paramount:
- Oil & Gas Processing Plants
- Chemical Processing Facilities
- Nuclear Power Plants
- Power Generation Facilities [1, 2, 3]
Finding More Information:
Obtaining detailed information on discontinued safety-rated parts can be challenging. Here are some resources, although finding success might be limited:
- Contact HIMA Support: You can try contacting HIMA customer support to see if they have any remaining stock or documentation for the Z7116 [1].
- Online Resources: Search for “HIMA Z7116 user manual” or “HIMA Z7116 datasheet” online. You might find some references on older automation parts supplier websites or engineering forums, but the information might be less reliable or outdated.
Important Safety Note:
If you’re working with a HIMA safety control system and require a connection cable for digital inputs, it’s highly recommended to consult the system documentation or contact HIMA support. Using a discontinued cable like the Z7116 is not recommended, as it might not be compatible with newer systems and could compromise safety. They can advise on suitable replacement options that meet current safety standards and ensure safe and reliable operation within your system.
