The Edwards Est SIGA-MCR Control Relay Module provides a Form “C” dry relay contact to control external appliances such as door closers, fans, dampers etc. Also, this device does not provide supervision of the state of the relay contact. Instead, the on-board microprocessor ensures that the relay is in the proper ON/OFF state. Upon command from the loop controller, the SIGA-MCR relay activates the normally open or normally-closed contact.
The Edwards Est SIGA-MCR function identically to the standard mount versions, but take advantage of the modular flexibility and easy installation that characterizes all UIO modules. Two- and six-module UIO motherboards are available. Besides, all wiring connections are made to terminal blocks on the motherboard.
SIGA-MCR mount the UIO motherboard inside a suitable EDWARDS enclosure with screws and washers provided. Furthermore, plug the module into any available position on the motherboard and secure the module to the motherboard with the captive screws. In Addition, UIO motherboard terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2) wire size.
