HIMA F3237 digital input module

HIMA F3237 digital input module

Input characteristic
Input channels: There are eight input channels.
Input signal type: Supports dry contact or wet contact input, compatible with a variety of field equipment output signal forms, such as can be connected to DIN 19234 (NAMUR) standard proximity switches and resistance sensors.
Input voltage and current: Support 24V DC voltage, input current is 10mA.
Signal isolation: Electrical isolation technology is used between the input channel and the internal circuit, and the isolation voltage can usually reach a high level to effectively prevent external interference signals from entering the control system.
Line impedance and line length: line impedance ≤50 ohms (according to DIN 19234), line length ≤1000m (line diameter of 0.5mm²).

Functional characteristics
Diagnostic function: With automatic self-detection function, the module will be fully self-checked during operation, including switching capability test, zero crossing test, input circuit crosstalk test, input filter function test, module calibration function test, sensor circuit short circuit and wire break test, etc., to ensure its normal operation.
Input filtering: The module has input filtering function, which can suppress noise and interference and improve the stability and reliability of the input signal.
Short circuit and break protection: with sensor line short circuit and cable break protection function, enhance the safety and stability of the module.
Communication protocol: supports CANopen communication protocol, and can also be integrated with other systems through a variety of communication protocols such as Ethernet, Profibus, Modbus, etc., to facilitate data interaction and remote monitoring.

authentication
The module is certified to DIN EN 62061 in accordance with the standards for safety-related systems and is suitable for industrial automation and control systems with high safety and reliability requirements.
