Number of Channels 16 fail-safe analog channels
Input Signal Range 0 to 4.1 V (converted from 0-20 mA via FTA-T-14 or 10105/A/1)
A/D Converter Resolution 12-bit (inaccuracy ± 1 LSB)
Module Inaccuracy < 0.25%

Channel-to-Channel Isolation and Fail-Safe Execution

Designed for SIL3 / AK1-6 safety instrumented applications, the module features high-impedance input architecture (> 1 MOhm) with crosstalk suppression exceeding 60 dB to maintain signal integrity across high-density loop configurations. Galvanic isolation and external voltage readback capabilities (0 to 4.1 V) enforce continuous diagnostic coverage and immediate fail-safe state execution in the event of field loop anomalies or backplane signal disruption.

Frequently Asked Questions

Q: How are standard 0-20 mA or 4-20 mA field current signals conditioned for this module?

A: Current-to-voltage conversion (0-20 mA to 0-4.1 V) must be executed using either the FTA-T-14 Field Termination Assembly or the 10105/A/1 conversion module mounted on the rear backplane programming connector (Px).

Q: What safety classification does the module support in redundant configurations?

A: The module is certified for safety class AK1-6 in single mode and achieves AK6 performance levels when deployed in dual redundant hardware setups.

Q: Can this module withstand accidental high-voltage wiring errors on the input channels?

A: Yes, each input channel is protected against sustained overvoltage conditions up to an absolute maximum input limit of ± 36 VDC without permanent board damage.

Field Installation Guidelines

  1. Mount the 4 HP, 3U module into the specified slot of the 19-inch FSC subrack, ensuring correct alignment with backplane guide rails.
  2. Ensure the 10105/A/1 conversion module is firmly seated on the corresponding Px connector on the backplane if FTA-T-14 field termination assemblies are not utilized.
  3. Keep field analog signal cabling routed in twisted, shielded pairs, connecting the shield ground exclusively at the designated system earth point.
  4. Check that external 24 VDC power supply ripple does not exceed safety limits before powering up the channel inputs.
