HIMA F3335 4-channel output module

The HIMA F3335 is a 4-channel output module certified for safety-related applications up to SIL 3 per IEC 61508. It is specifically designed for controlling intrinsically safe solenoid valves and for supplying 0/4-20 mA intrinsically safe transmitters. The module allows installation of valves and transmitters in potentially explosive atmospheres from Zone 1.

FEATURES:

• Intrinsically Safe & Safety-Related Design
  Certified for safety-related applications up to SIL 3 according to IEC 61508. ATEX certified for Ex zone 1 ([EEx ib] IIC). Four intrinsically safe voltage outputs with current limiting, suitable for controlling solenoid valves and supplying 0/4‑20 mA transmitters in hazardous areas.

• Output Characteristics
  Nominal output voltage 19 V at 20 mA load; no‑load voltage 24 V; short‑circuit current 52 mA (module is short‑circuit proof). Switching time approx. 15 ms; reset time 35 to 270 ms (load dependent). Each channel operates independently.

• Redundant Operation & System Integration
  Two output circuits of one or two F3335 modules can be wired in parallel for redundant operation. Designed to be mounted in a 19" subrack with forced ventilation (fan K9203 or, in H41q system, fan K9212 directly under the module).

QA:

Q1: What is the safety integrity level (SIL) of the F3335?
A1: The F3335 is certified for safety-related applications up to SIL 3 according to IEC 61508.

Q2: Can the F3335 be used in hazardous areas?
A2: Yes, it has ATEX EC Type Examination Certificate for [EEx ib] IIC, suitable for Zone 1 applications. The outputs are intrinsically safe.

Q3: What types of field devices can be connected?
A3: It can control intrinsically safe solenoid valves (see list in datasheet) and supply 0/4-20 mA intrinsically safe transmitters.

Q4: Does the module require cooling?
A4: Yes, forced ventilation via fan (K9203 or K9212) is mandatory. In H41q subrack, fan K9212 must be installed directly under the module.

Q5: Can outputs be wired in parallel?
A5: Yes, two output circuits of one or two F3335 modules can be wired in parallel for redundant operation, respecting reduced maximum values.
