Attributes . Isolated channels (no bus) allow control of each relay by a different logic system, if necessary. Mix sourcing (positive switching, Vcc on⁄off) and sinking (negative switching, ground on⁄off) on a single multi-relay module. Provide spare relay channels for future needs without committing to a specific logic power supply, and without committing coil-drive power for more than one relay at a time. This relay modules provide high density packaging of miniature general purpose relays with double pole double throw (2 Form C) contact configurations and low current AC and DC coils. Can load own relays in RC relay carrier, or order the RM relay module complete with relays. . Names
