HIMA F6217 8-Channel Analog Input Module

Description

The HIMA F 6217 (F6217) is a safety-related 8-channel analog input module designed for safety-critical industrial applications up to SIL 3 according to IEC 61508. The HIMA F 6217 features a redundant, safety-related processor system containing microcontrollers uC1, uC2, and uC3 to execute integrated self-tests directly on the module. Built with safe isolation, the module processes standard current inputs (0/4...20 mA) and voltage inputs (0...5/10 V) with a 12-bit resolution. Internal test routines continuously evaluate A/D converter linearity, A/D converter overflow, channel crosstalk, input filter functionality, and I/O bus communication. Recognized errors generate individual channel bit faults that are interpreted and evaluated within the user program in ELOP II.

Installation Guidelines

• Shielding & Cabling: Screened cables must be used for field input circuits, and twisted cables are recommended to achieve full interference immunity. Cabling without screening is only acceptable if the transmitter environment is free from interference and distances are relatively short (e.g., inside a cabinet).
• Power Supply Separation: Cables for the power supply must be locally separated from field input circuits.
• Grounding: Suitable earthing measures must be strictly applied. Flat pin plug 6.3 x 0.8 mm2 on cable screen connections must be attached to the earth bar located under the slot.
• Cooling & Temperature: External measures against temperature rises inside cabinets (e.g., installing cabinet cooling fans) must be provided.
• Unused Inputs: Terminate unused 0...5 V voltage inputs using jumpers. Terminate unused current inputs with the shunt, and unused 0...10 V voltage inputs with the voltage divider in the cable connector.
• Low-Frequency Interference: In environments subject to ~10 Hz external pressure pulses (such as near piston pumps), enable sensor digital filtering or implement an optional H 7017 low-pass filter to prevent temporary channel bit faults.
• Special Transmitter Isolation: If using transmitters with internal Zener diodes (e.g., Saab/Rosemount 3300 GWR), galvanic isolation (e.g., HIMA H 6200 HART isolator) must be implemented in the signal line. Note that cable plug Z 7128 must not be used with Zener barriers.
• Maintenance: No routine maintenance is required. In the event of a module failure, the device de-energizes and must be replaced.
