Rated for either 18 v max with a 12 v dc coil rating or 36 v max with a 24 v dc coil rating. This is also called a “changeover” device because the common contact changes. Versions are available with either a 20 a or 40 a continuous current rating. Web a “ form b ” would mean the contacts are normally closed when the coil of the relay is not energized or the there is no magnetic field nearby in a reed switch. It controls two circuit i.e. Broad offering of form a (spst), form 2a (spst with two terminals), and form c (spdt) relay options. A “ form c ” would have 3 leads and would have 1 normally open and 1 normally closed circuit. One circuit remain open while the other remains closed. The terminals are isolated from signal ground. Provides eight form c relays.
[6] a single form c contact isn’t much good unless you are trying to design a system whose pl only requires pl a or pl b , but adding a second contact to this device adds the possibility of monitoring the. Allows remote control of relays. Rated for either 18 v max with a 12 v dc coil rating or 36 v max with a 24 v dc coil rating. One circuit remain open while the other remains closed. Web form c relay digital output: It controls two circuit i.e. The form c digital outputs are switching contacts with one common terminal (c), one normally open terminal (no), and one normally closed terminal (nc). 1 a at 30 vdc relay contact rating. A “ form c ” would have 3 leads and would have 1 normally open and 1 normally closed circuit. [6] a single form c contact isn’t much good unless you are trying to design a system whose pl only requires pl a or pl b , but adding a second contact to this device adds the possibility of monitoring the. Provides eight form c relays.
