HIMA 52100 Logic function module

Overview

The HIMA 52100 is a safety-certified, hardware-coded Time Delay Module belonging to the HIMA Planar 4 systems. This legacy module is engineered for high-integrity, functional safety applications such as Emergency Shutdown Systems (ESD) and critical machine control.

Planar4 modules

• Basic logic modules: AND, OR, NOT/block (4-8 gates per module)

• I/O: line monitored connections (circuit break, short circuit)

• Timing/delay modules (SIL3 instead of SIL4 due to a bit of firmware on chip)

• Communications / monitoring via Profibus, Modbus, or OPC

• Installation in standard 19 inch sub-racks

Planar4 Safety-related design

• All Planar4 cards implement safety-related logic, i.e., minimized failure probabilities and known failsafe states

• Example: AND gate

A simple relay-based AND gate

HIMA Planar4 AND-gate. The internal design is based on dynamic signaling driven by a signal generator. A simultaneous failure of up to three separate components leads to the output being de-energized.
