The IT-R4 is a multi-purpose switch or logic-level-activated Relay Module. Four user-configured relays are controlled via five input ports that accept a switch contact closure or logic-level input. A four-position configuration dip switch sets the operating behavior of the relays. Each relay can be set for different operating modes; "On, "Off", pulsed for a ¼ of a second, or toggled, which changes the relay to the opposite state.
Power Requirements: Power Supplies are sold separately. One Power Supply can power up to (5) IT-R4 and IT-R4S modules, saving wiring headaches and money.
