HIMA F60DIO24/1601 Mixed Digital I/O Module

The HIMA F60DIO24/1601 is a versatile safety I/O module that combines 16 digital inputs and 8 digital outputs in a single unit. Part of the F60 series, it is designed to maximize I/O density while maintaining SIL 3 capability per IEC 61508. This module is ideal for applications where space is limited but both input sensing and output actuation are required in close proximity.

Channel Configuration

• Digital Inputs: 16 channels, 24 V DC, type 3 according to IEC 61131-2

• Digital Outputs: 8 channels, 24 V DC, 0.5 A per channel (high-side switching)

All inputs are equipped with diagnostic capabilities including wire-break detection, short-circuit monitoring, and configurable input delays. The outputs include overcurrent protection, thermal shutdown, and open-circuit detection.

Safety and Diagnostic Features

The F60DIO24/1601 employs a 1oo2 architecture for safety-related processing, ensuring that any single fault does not lead to a loss of safety function. Inputs can be configured to accept test pulses from the controller, enabling detection of cross-circuits or shorts. Outputs are monitored for proper switching and can be forced to a safe state upon system demand. The module also provides a cyclic self-test routine that verifies internal hardware integrity.

Integration with Safety Controllers

Compatible with HIMA HIMax, Planar4, and HIMatrix systems, the module communicates over the internal backplane bus. Configuration is done via ELOP II, where each channel can be individually named, monitored, and assigned to safety logic. The module supports hot-swapping, allowing replacement without powering down the system, which is crucial for continuous operations.

Typical Applications

This mixed I/O module is frequently used in:

• Burner management systems (flame detection + valve control)

• Emergency shutdown panels (pushbutton inputs + solenoid outputs)

• Compressor control units (sensor feedback + actuator commands)

• Remote I/O cabinets with limited backplane slots

Environmental and Mechanical Specifications

The module is rated for operation from -20 °C to +60 °C and withstands vibration according to IEC 60068-2-6. It fits into standard F60 mounting racks and includes a removable front connector for easy wiring. All terminals are labeled with channel numbers and functional markings.

Certifications

Certified by TÜV for SIL 3 (IEC 61508) and suitable for use in SIL 3 safety instrumented functions (SIF) per IEC 61511. It also meets CE, UKCA, and UL 61010-1 requirements. The module is part of HIMA’s long-term lifecycle management program, ensuring availability for existing and new projects.

By combining input and output capabilities in a single module, the HIMA F60DIO24/1601 reduces complexity, lowers wiring costs, and maintains the highest safety integrity, making it a preferred choice for compact safety automation tasks.
