F3113A is a 16-channel digital input module (SIL3) of the German HIMA (Black Horse) F3 series. It is an old 19-inch rack-mounted model that has been discontinued and is only available in spare parts.

I. Basic Information

Model: F3113A (F3 113A)

Series: HIMA F3 (19" Rack-mounted Safety System, Non-Closed-loop F30/F35)

Type: 16-channel DI Safety Input Module (Not a CPU, requires F3112 or similar CPU)

Safety Level: SIL3 (IEC 61508), TÜV Certification; Cat.4/PL e

Programming software: ELOP II (old version)

II. I/O AND ELECTRICAL SPECIFICATIONS

Digital Input DI: 16 channels

Voltage: 24VDC (rated 20.4–28.8V)

Type: Source type / Drain type compatible

Current: Each channel ≥ 2mA@15V, ≤ 1.5mA@5V

Isolation: Channel-to-channel non-isolation, system-side safety isolation

Diagnosis: Short circuit / open circuit detection, LED status indication

Power supply: 24VDC (18–30VDC), power consumption approximately 5W

Environment: 0℃ to +60℃, IP20

Size / Weight: 19" rack, 3U; approximately 1kg

III. Core Features

Safety Architecture: Dual-channel redundant input, fail-safe design

Diagnostic Capability: Full coverage DI fault diagnosis, can be reported to CPU

Backplane Bus: F3 series dedicated safety bus, communicates with F3112/F3114 and others CPUs

Installation: 19" rack F3 enclosure, hot-swappable support

IV. Differences from F3112 (you just checked)

F3113A: Pure 16DI input module, no CPU, requires F3112/F3114 and others CPUs to be paired

F3112: F3 system CPU, 16DI + 8DO integrated I/O, can operate independently

V. Alternative Suggestions

Direct Replacement: F3001 (compact SIL3 CPU, integrated 20DI + 8DO, current mainstream)

Module Replacement: F3DIO8/801 (8DI + 8DO, SIL3, DIN rail)

System Upgrade: HIMatrix F35 or HIMax (SILworX, modern communication, full series I/O)
