Product Information
Full details
This Phoenix Contact Safety Relay Module (1148703) is designed for industrial automation applications requiring reliable safety control. It offers dependable operation with force-guided contacts, ensuring safety integrity. A potential caveat is the specific 24V DC input voltage requirement, limiting its direct use in systems with different voltage standards. Key features include push-in connections for easy installation, a status LED for quick diagnostics, and compliant safety relay functionality.

Extended Product Information
FAQs
What type of connection does this safety relay module use?
This module features push-in connection technology, allowing for fast and tool-free wiring of conductors.
What is the contact configuration of this module?
The module has a configuration of 3 normally open (N/O) contacts and 1 normally closed (N/C) contact.
What is the operating voltage for this safety relay?
The module operates on a 24V DC input voltage.
What does 'force-guided contacts' mean?
Force-guided contacts (compliant to DIN EN 61810-3) ensure that the status of the N/O and N/C contacts are mechanically linked. If one contact welds or fails to open, the other contacts will not change state, guaranteeing predictable behavior for safety.
What is the protection rating (IP rating) of this module?
The module has an IP20 protection rating, meaning it is protected against solid objects larger than 12.5mm but is not protected against water ingress.
What is the switching voltage capacity of the contacts?
The contacts can handle a switching voltage of up to 250/300V AC/DC.
Can this module be used in extreme temperature environments?
Yes, the module has a wide operating temperature range of -40°C to +60°C, making it suitable for many demanding industrial conditions.
Troubleshooting
Module does not power on (no status LED indication)
Verify that the 24V DC power supply is correctly connected and providing the specified voltage. Check the polarity of the power connections. Ensure the power supply is functional.
Safety outputs do not activate when expected
Check that all input safety devices are in their normal (safe) state. Verify wiring to input and output terminals for correctness and secure connections. Ensure the module has received the correct 24V DC input voltage.
Status LED shows an error code or is flashing
Refer to the manufacturer's detailed technical documentation for specific LED error code meanings. Common causes include incorrect wiring, input voltage outside range, or internal fault.
Intermittent operation or unexpected tripping
Inspect for loose wiring connections. Ensure the operating environment is within the specified temperature range. Check for electrical noise or interference on power or signal lines that might be affecting operation.
Pros and Cons
Pros
- Ensures safety integrity through force-guided contacts.
- Fast and simple installation with push-in connection technology.
- Clear operational status indication via integrated LED.
- Robust design suitable for harsh industrial environments.
- High mechanical life cycle of 100,000,000 cycles.
Cons
- Requires a specific 24V DC input voltage.
- Limited to 3 N/O and 1 N/C contact configuration.
- IP20 rating means it's not suitable for direct exposure to moisture or dust.
- Relatively fixed configuration may not suit all complex safety scenarios without additional components.
Setup, Compatibility & Care
Setup:
- Mounting: Securely mount the module onto a standard DIN rail using the integrated retaining bracket.
- Wiring: Connect the 24V DC power supply to the designated input terminals. Wire the safety input devices (e.g., safety switches, E-stop buttons) to the appropriate input terminals. Connect your actuators or control circuits to the N/O and N/C output terminals as per your safety design.
- Verification: After wiring, ensure all connections are secure. Power up the system and verify the status LED indicates the correct operational state (e.g., green for ready/active, red for fault/tripped).
Compatibility:
- Input Voltage: Requires a stable 24V DC power supply.
- Contact Ratings: Suitable for switching up to 250/300V AC/DC. Always ensure your controlled loads are within these limits.
- Environment: Designed for industrial environments with an IP20 rating. Avoid installations where exposure to water, excessive dust, or corrosive materials is expected.
Care:
- Cleaning: Disconnect power before cleaning. Use a dry, lint-free cloth to wipe down the exterior of the module. Avoid using solvents or abrasive cleaners.
- Inspection: Periodically inspect wiring connections for any signs of damage or loose connections. Ensure the status LED is functioning correctly.
