System compatibility

Designed for HIMA HIQuad X PES safety system,used to drive field solenoid valves and safety actuators,widely used in petrochemical,chemical plant ESD emergency shutdown and F&G fire gas protection system.

Function

SIL3 8-channel digital safety output module.It receives safety control commands from HIQuad X safety controller and outputs 24V DC signal to field actuators and solenoid valves.Each channel has independent readback circuit to verify actual output status.Short-circuit and channel failure will trigger fault alarm and send diagnostic data to safety controller.

Installation

Clip onto standard 35mm DIN rail in control cabinet,connect field actuator wiring via Z7126/Z7127 terminal plug,configure channel parameters via SILworX engineering software.

Interface

‑Field signal wiring connector interface

‑Internal safety bus connector

‑LED indicators for channel run and fault status

Circuit feature

Fail-safe safety output design,permanent channel readback diagnosis,short-circuit protection,galvanic isolation,strong anti-electromagnetic interference,meets SIL3 functional safety requirements for hazardous industrial environment.

Feature

HIQuad X series SIL3 digital output module Z7138. Common faults:terminal loosening,cable aging,internal output circuit damage.Confirm system firmware before replacement.

Diagnostic

Short circuit,output abnormal or internal hardware fault triggers fault alarm;controller executes safety interlock logic.

Built‑in function

Z7138 outputs safety control signals to field actuators for SIS safety instrumented system emergency shutdown protection,widely used for process plant safety spare replacement.

Product Brief

Z7138 belongs to HIMA HIQuad X family,DIN rail mounted SIL3 8-channel digital safety output module with channel readback diagnosis. Verify system compatibility before ordering.Test output and diagnosis function during commissioning. ESD anti‑static protection shall be followed during installation.
