Dual-channel configuration; two dry-contact or NAMUR proximity switch signals are each isolated and converted to relay outputs. DIP switches allow setting of same-phase/inverted logic (default same-phase), line fault monitoring on/off (default on, LED flashes on line fault) and the second output function. Requires independent power supply; three-way isolation between input, output and power supply.
Note:Three-way isolation between input, output and power supply. 24V DC independent power supply; two inputs each connect to a dry-contact switch or NAMUR proximity switch (NAMUR/dry-contact switches connected per channel); both outputs are relay contacts, permitting a load of 250VAC/2A or 30VDC/2A. Module indicators: green power indicator, red fault signal, yellow channel status. All terminals are hot-swappable. Refer to the silkscreen on the module side for specific terminal numbers.
Ordering information:
- Requires independent power supply (18V DC~32V DC).
- DIP switch function settings must be confirmed before commissioning.
