Honeywell 10012/1/2 Module Central Processing Unit Flash Memory

The Honeywell 10012/1/2 (10012/1/2 Module Central Processing Unit Flash Memory) operates as a processing and memory module within Honeywell safety control architectures. The module provides central processing functionality, analog signal acquisition, data handling, and execution support for control applications requiring monitored input processing and system-level diagnostics.

Hardware Specifications

Channel-to-Channel Isolation and Signal Processing

The 10012/1/2 module incorporates sixteen analog input channels with integrated analog-to-digital conversion capability. The input architecture supports voltage measurements from 0 V to 4.1 V while maintaining input resistance greater than 1 MOhm to minimize loading effects on connected field circuits.

A 12-bit A/D converter is utilized for signal digitization, with specified converter accuracy of +/-1 LSB and overall module accuracy below 0.25%. Channel separation performance exceeds 60 dB cross-talk suppression, reducing signal interaction between adjacent input channels during acquisition and processing operations.

External voltage readback functionality permits verification of input signal conditions through the module measurement circuitry, supporting diagnostic and maintenance activities.

Redundancy and Safety System Integration

The module is designed for operation within Honeywell safety-related control environments and supports AK1-6 safety classifications. When deployed in redundant configurations, operation is specified for AK6 safety requirements.

Power is supplied through both 5 VDC and 24 VDC system rails. The compact module form factor occupies 4 TE and 3 HE of rack space, enabling integration within high-density control system assemblies.

Signal acquisition, processing operations, and diagnostic functions are synchronized through the CPU architecture to support control system execution requirements and monitored data handling functions.

Frequently Asked Questions

Q: How many input channels are available on the module?
A: The module provides 16 input channels for voltage signal acquisition.

Q: What is the maximum allowable input voltage?
A: The specified absolute maximum input signal is +/-36 VDC.

Q: Does the module provide protection against channel interaction?
A: Yes. Channel cross-talk suppression is specified at greater than 60 dB.

Field Installation Guidelines

• Verify software revision compatibility before installation into the target control system.

• Confirm proper rack space allocation of 4 TE and 3 HE before mounting.

• Ensure power supply sources meet the specified 5 VDC and 24 VDC requirements.

• Route low-level analog input wiring separately from high-current power conductors.

• Use shielded instrumentation cables where required by plant engineering standards.

• Verify input signal levels remain within the specified operating range before energizing the module.

• Perform channel verification and diagnostic testing after installation and before commissioning.
