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 has improved robustness against noise on communication lines. Another improvement over similar products are failsafe configuration options.
PoRelay8–CAN 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 4 mounting holes.
PoRelay8 is in stock with 12 V relays.
The PoRelay8 replaces the PoExtBusRE output extension device. Although, the PoRelay8 has the same physical dimensions as PoExtBusRE, it is a significant upgrade in reliability, robustness to electricla noise and functionality.
Industry standard CAN-bus allows chaining of multiple PoRelay8 CAN relay devices. Moreover, embedded error checking algorithms prevent electrical noise from affecting the state of the outputs. First PoRelay8 still connects directly to the PoKeys device using the PoExtBus. With PoKeys57 series devices, even data over PoExtBus connection is protected with error detection, making the solution trustworthy.
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 doesn’t depend on the physical order of the devices. Instead, PoKeys aplication provides easy setup of device configuration and logical position in the sequence.
