Sensors, Modules & Relays

The HIMA F6214 reads analog signals for safety-critical applications. This module supports 0/4–20 mA inputs from field sensors. It fits directly into HIMA H41q and H51q safety systems. You will rely on this unit for emergency shutdown and fire protection.

Technical Specifications Overview

This analog input module provides eight isolated input channels. Each channel features a separate 24 V DC loop supply. The HIMA F6214 also performs continuous self-diagnostics on every cycle. A built-in comparator checks two redundant measurement paths. Therefore, single faults cannot compromise the safety function.

Internal Design and Energy Storage

The HIMA F6214 contains one main PCBA with 86 discrete components. Key parts include eight precision shunt resistors for current sensing. The module also holds two electrolytic capacitors storing 330 µF of energy. This storage handles brief power interruptions up to 10 milliseconds. Moreover, an onboard FPGA manages all signal processing redundantly.

Physical Interfaces and Connections

You will find two front-facing 20-pin connectors on this module. These connectors accept standard HIMA termination boards like F6217. Each wire connects to a screw-type terminal block externally. A green LED indicates proper module operation without faults. A red LED will flash for any internal channel error. Four locking latches secure the HIMA F6214 firmly in its slot.

Installation and Operational Reliability

Install this analog input module in a protected control cabinet. Leave 40 mm of space above for proper heat dissipation. The module performs a power-on self-test automatically each startup. Consequently, you gain immediate verification of healthy hardware. This design supports failsafe systems running 24/7 for many years.
