HIMA Z7116 digital input pre-wiring module

Wiring & Indicator ConfigurationEquipped with a 16-pin cable: one end features a 9-pin DIN connector, and the other end has 2-pin terminal blocks, meeting standard wiring needs in industrial scenarios. The module is fitted with 16 LED indicators (mostly red), which can intuitively display the working status of digital inputs (DI). It also has built-in shunt resistors to effectively prevent LED damage caused by abnormal current, extending the service life of the indicators.
Power Supply & Compatible VoltageComplies with industrial universal power supply standards, with a typical supply voltage of 24V DC. It is compatible with the power configurations of most industrial control systems, reducing the difficulty of power adaptation during system integration.
Environmental AdaptabilityOperating temperature range: -20°C to 60°C, capable of coping with regular temperature fluctuations in industrial sites such as chemical plants and oil fields. It is suitable for installation inside control cabinets, meeting the harsh usage requirements of industrial scenarios.

Safety Diagnostics & Fault ToleranceAs a safety-related accessory, it has basic self-diagnostic functions. It can work with HIMA main controllers to quickly detect wiring faults or signal abnormalities, facilitating on-site personnel to troubleshoot problems in a timely manner. It also supports integration with the system’s redundant configuration, improving the reliability of the overall safety control system and reducing the impact of single-point failures on the system.
Convenient Debugging OperationsSome supporting versions come with an operation panel. Through the panel, various parameters and control methods can be adjusted, and key information such as operating status, wiring I/O status, and fault causes can be displayed. This greatly simplifies on-site debugging work and lowers operation and maintenance difficulty.
