System adaptation

Safety system: HIMA HIMax

Matched I/O module: X-AO 1601 (single or redundant configuration)

Designed as the dedicated isolation / termination module for HIMax analog output safety loops

Core functions

On-site signal wiring for analog output safety loops

Physical isolation between the hazardous (field) side and the safe (system) side

Fault bus connection and status feedback to the safety controller

Supports safe separation of dangerous-side circuits from system electronics

Electrical & interface characteristics

Recommended isolation module: HiC2031 (AO-specific)

Power supply: 24 VDC, supports redundant power supply concepts

Hazardous area interface:

Blue spring terminals (field / dangerous zone)

Safe area interface:

96-pin system connector to HIMax backboard

Fault feedback:

Isolated fault output (power supply missing / field-side error)

Potential-free contact for alarm and interlock signaling

Mechanical & environmental design

Housing material: Fiberglass-reinforced plastic

Design features:

High resistance to vibration

Strong EMI immunity

Optimized for long-term operation in industrial safety cabinets

Typical applications

SIS analog control loops, such as:

Safety valve positioning

Speed regulation in safety-related drives

Used in process safety systems requiring reliable analog output isolation

Key features & advantages

Safe isolation

Physical separation of hazardous and safe circuits

Fully compliant with IEC 61508 functional safety requirements

Fault diagnostics

Fault bus supports daisy-chain connection

Fault and status signals can be routed directly to the control system for alarms and interlocking

Plug-and-play integration

Precisely matched to HIMax backplanes and X-AO 1601 modules

Minimizes cabinet wiring, commissioning, and debugging time

Explosion-proof adaptation

Blue terminals suitable for Zone 2 and similar hazardous areas

Meets industrial explosion-protection and safety standards
