The Edwards SIGA-CRH High Power Control Relay is an addressable device design for interface applications that require a high voltage, high current relay. Two identical sets of relay terminals are provided. Both sets of relay contacts transfer when the module is activated or restore. The state of the output terminals is not supervise.
The module requires one address on the signaling line circuit (SLC). The address is assign electronically. In addition, there are no address switches to set. The High Power Rating 120/240 VAC or 24 VDC rated contact can be use to control external appliances such as door closers, fans, dampers etc.
Some of the features and specifications can be describe below, for example:
- Provides one relay with two.
- Automatic device mapping.
- Removable terminal blocks.
- Electronic addressing.
- Intelligent device.
Also, the Edwards SIGA-CRH High Power Control Relay signature modules transmit information to the loop controller regarding their circuit locations with respect to other Signature devices on the wire loop. In detail, easy wiring and module replacement. Programmable addresses are download from the loop controller or PC; there are no switches or dials to set. Moreover distributed intelligence allows lower communication speed with substantially improved control panel response time and less sensitivity to line noise and loop wiring properties; twist or shield wire is not require.
