The Omron H3CR-A8E 100/240VC, also cataloged as the H3CR-A8E Solid-State Timer, operates as a dedicated hardware component for time-delay switching and sequence control execution within industrial control panels.

Model Nomenclature & Functional Code

• H3CR: DIN 48 x 48 mm solid-state timer module platform
• A8: 8-pin socket connector physical interface configuration
• E: Time-limit contact (SPDT) combined with instantaneous contact (SPDT) relay output
• 100/240VC: 100 to 240 VAC wide-range supply voltage rating

Technical Parameter Specifications

Firmware Interfacing & Modular Control Performance

The module integrates seamlessly into discrete control circuits alongside distributed PLC platforms. Internal firmware flash compatibility and deterministic execution ensure high repeat accuracy during cyclic switching. High-density I/O density scaling allows synchronized multi-point relay tripping across centralized control cabinets while maintaining backplane bus communication velocity Licences across linked EtherCAT or EtherNet/IP remote sub-bus networks.

Standard Module Accessories

• 1 x H3CR-A8E 100/240VC Solid-State Timer Unit
• 1 x Front Panel Protective Setting Dial Ring
• 1 x Terminal Pin Configuration Sheet

Cabinet Installation & Field Cabling Directives

Mounting Procedure

• Insert the 8-pin base into an industrial P2CF-08 DIN-rail socket or track-mounting base until fully latched.
• Ensure adequate spacing around panel cutouts to prevent thermal accumulation under continuous coil energization.

Wiring & Insulation Guidelines

• Wire signal and supply leads securely to the 8-pin socket terminals using proper wire ferrules.
• Separate AC control lines from low-voltage DC sensor cables to eliminate inductive switching noise interference.

Technical Inquiry Resolutions

• What output contact arrangement is provided on the H3CR-A8E?

  The unit features one SPDT time-limit relay output and one SPDT instantaneous relay output.

• What supply voltage range is accepted by this model?

  The unit operates on 100 to 240 VAC (50/60 Hz) or 100 to 125 VDC control power sources.

• How is the physical electrical connection established?

  Connection is made via a standard 8-pin round plug-in base compatible with DIN-rail sockets.

• Can time parameters be adjusted on the front panel?

  Time range selector switches and a rotary dial allow precise setting of delay timing ranges.

• What precautions must be taken regarding hot-swapping?

  Power must be isolated from the socket before pulling or inserting the timer module assembly.

• Is the relay output suitable for driving inductive loads?

  Inductive loads require external surge suppressors across contacts to prevent premature contact erosion.

• How does the instantaneous contact function relative to coil power?

  The instantaneous SPDT contact transfers immediately upon coil energization regardless of time delay settings.

• Does the timer retain setting accuracy under temperature variations?

  Solid-state timing circuits maintain high repeat accuracy across the ambient operational span of -10 deg C to 55 deg C.
