HIMA 80105 984080105

This is a digital input module for the HIMax series. It belongs to the professional safety relay and programmable safety control system product line produced by HIMA.

Detailed Product Description

1. Product Name & Model Number

• Brand: HIMA

• Product Series: HIMax

• Model: 80105

• Part Number / Order Number: 984080105

• Description: Digital Input Module for Safety Relay Systems

2. Key Functions

• Safety Signal Acquisition: Receives switch signals from passive contacts (e.g., Normally Open or Normally Closed contacts).

• Dual-Channel Design: Adheres to the redundancy principle of safety systems. It typically features two independent input channels for connecting two-channel sensors or actuators (e.g., one NO and one NC contact) to achieve higher safety integrity.

• Diagnostics & Monitoring: The module features internal diagnostics to monitor the status of the input wiring for faults such as wire break, short circuit, or cross-circuit.

• Status Indication: The module front features LED indicators to display the status of each channel (e.g., signal present, fault, power OK), facilitating quick commissioning and troubleshooting.

• Communication with Central Unit: Transmits the acquired signal status securely via the backplane bus to the central processing unit of the HIMax system for logic processing.

3. Key Features**

• High Safety Integrity: Designed specifically for safety applications, complying with relevant safety standards (e.g., IEC 61508, IEC 62061, ISO 13849).

• High Reliability: Features robust design and high-quality components, suitable for demanding industrial environments.

• Flexibility: Input parameters (e.g., contact type, response time) can be configured via coding switches or configuration software.

• Easy Integration: As part of the HIMax system, it can be easily combined with other HIMax modules (e.g., output modules, logic modules) to build complete safety solutions.

• Screw Connection: Utilizes reliable screw terminals for secure wiring connections.

4. How It Works**

1. Signal Connection: Field safety devices (e.g., contacts from an E-Stop button) are wired to the module’s input terminals.

2. Signal Conditioning & Reading: The module’s internal electronics provide a monitoring voltage to the field contacts and read their open/closed status (“0” or “1”).

3. Signal Processing & Diagnostics: The module processes the read signals and performs continuous diagnostics to detect any faults that could compromise the safety function.

4. Data Transmission: The processed and validated signal status is sent via the internal backplane bus to the system’s central processing unit.

5. Logic Decision: The central processing unit evaluates the input signals based on the pre-defined safety logic (e.g., if the E-Stop is pressed, the machine must stop) and commands the output modules to execute the corresponding safety action (e.g., cutting power to the main circuit).

5. Typical Applications**

This module is widely used in areas requiring high-integrity safety control, such as:

• Emergency Stop (E-Stop) Systems

• Safety Door / Guard Monitoring

• Two-Hand Control Devices

• Light Curtains and Safety Mats

• Safety Limit Switches for pressure, temperature, or level

• Basic Process Control Systems in Process Industries

6. Role within the HIMax System**

The HIMA 80105 DI module acts as the “sensory nerve endings” of the HIMax safety system. It is responsible for collecting the most critical safety status signals from the field, serving as the starting point of the entire safety chain. Without reliable digital inputs, the safety system cannot correctly perceive hazards and therefore cannot initiate the proper response.
