4 Relay Outputs
The CAN-CBM-REL4 is equipped with 2 changeover contacts (PDT) and 2 normally open contacts (NOC). The relay outputs can switch starting currents up to 2 A and voltages up to 220 VDC/250 VAC. The maximum switching power is 62.5 VA. The contacts can be switched at a maximum on-period of 20 cycles per minute.
The electrical isolation of the channels allows simultaneous connection of various voltages to the module.

Local Microcontroller
A 505C microcontroller is used to handle the relays and the CAN.

CAN Interface
The ISO 11898-compliant CAN interface allows a maximum data-transfer rate of 1 Mbit/s. The CAN interface is electrically insulated by optocouplers and DC/DC converters. It is connected via screw/plug connectors.
