System compatibility

Designed for HIMA H41q / H51q PES safety system,matched with BV7040 / BV7046 bus cables,widely used in petrochemical,chemical plant ESD emergency shutdown and F&G fire gas protection system.

Function

Passive safety bus terminal module.It serves as transition interface between safety bus cable and field wiring,adopts 2-wire bus wiring structure.The built-in DIP switch is used to enable or disable bus terminal resistor for impedance matching.It ensures stable bus signal transmission and simplifies system wiring and maintenance.

Installation

Clip onto standard DIN rail in control cabinet,connect bus cable to 25-pole Min-D socket and field wires to terminal blocks.Set termination resistor switch when installed at the end of bus line.

Interface

‑25-pole Min-D socket

‑Two 6-pole spring terminal blocks

‑DIP switch for termination resistor

‑DIN rail fixing buckle

Circuit feature

Passive circuit design,signal impedance matching,compact structure,strong anti-electromagnetic interference,designed for safety-related hazardous industrial environment.

Feature

H41q/H51q series safety bus terminal H7506. Common faults:connector pin oxidation,terminal loosening,switch poor contact.Check bus wiring and switch setting before commissioning.

Diagnostic

Bad contact or wrong termination resistor setting causes bus communication failure;controller executes safety interlock logic.

Built‑in function

H7506 provides bus signal transition and impedance matching for SIS safety instrumented system emergency shutdown protection,widely used for process plant safety spare replacement.

Product Brief

H7506 belongs to HIMA H41q/H51q family,DIN rail mounted passive safety bus terminal module with 25-pole Min-D socket. Verify system and cable compatibility before ordering.Test bus communication during commissioning. ESD anti‑static protection shall be followed during installation.
