This CAN relay board allows expanding the number of outputs of the PoKeys device by using the PoExtBus. It features 8 relay outputs. Multiple boards can be daisy-chained with use of a CAN bus for up to 80 additional outputs.
CAN relay – PoRelay8 – Relay extension board with CAN bus
from 29,00 € excl. VAT & shipping
PoRelay8 – CAN relay allows expanding the number of outputs of the PoKeys device. Because of using noise imune PoExtBus Smart or CAN interface it’s very reliable.
Above all PoRelay8 – CAN relay has improved robustness against noise on communication lines. Another improvement over similar products are failsafe configuration options.
PoRelay8 – CAN relay incorporates 8 electromechanical relays with terminals for NO, NC and common relay contacts. There is one green LED for power supply indication and 8 additional LEDs for relay operation indications. The device can be mounted to a standard DIN rail using the DIN rail mount adapters or directly via 3 mounting holes.
Porelay8 is avaiable with 12V or 24 relays.
- Daisy chaining to 10 PoRelay8 boards from the single PoExtBus connector
- 8 built-in electromechanical relays with NO, NC and common contacts
- 5 wires board to board ribbon cable to connect to master device or chaining
- Improved reliability over original PoExtBusRe boards
- Daisy-chaining over CAN bus, allowing greater distances between each board in the chain hence much improved noise immunity
- Prepared for DIN rail mounting with DIN rail mount adapter
Comparison: PoExtBusRE vs. PoRelay8
The PoRelay8 replaces the (now obsolete) PoExtBusRE output extension device. The PoRelay8 has the same physical dimensions as PoExtBusRE. Above all upgraded hardware is improving reliability and robustness to electrical noise.
Industry standard CAN bus allows chaining of multiple PoRelay8 CAN relay devices. As a result noise doesn’t disturb communication. First PoRelay8 is still connected to PoKeys device using the PoExtBus. Improved error detection in PoKeys57 series devices is most noteworthy. First PoRelay8 CAN relay board acts as a bridge between PoExtBus and CAN. Because of simpler operation, logical order of the PoRelay8 CAN relay devices is not important anymore. Moreover PoKeys aplication provides easy setup of device output positions.
