Alpha Communications™ DUAL 16VAC>FORM 'C' RELAY UNIT
Form C Relay. 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. The form c digital outputs are switching contacts with one common terminal (c), one normally open terminal (no), and one normally closed terminal (nc).
Alpha Communications™ DUAL 16VAC>FORM 'C' RELAY UNIT
Allows remote control of relays. 1 a at 30 vdc relay contact rating. Web form c relay is spdt relay with double throw contact terminals known as nc and no. Versions are available with either a 20 a or 40 a continuous current rating. 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. The form c digital outputs are switching contacts with one common terminal (c), one normally open terminal (no), and one normally closed terminal (nc). Rated for either 18 v max with a 12 v dc coil rating or 36 v max with a 24 v dc coil rating. [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. 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.
Rated for either 18 v max with a 12 v dc coil rating or 36 v max with a 24 v dc coil rating. Web form c relay is spdt relay with double throw contact terminals known as nc and no. Versions are available with either a 20 a or 40 a continuous current rating. The form c digital outputs are switching contacts with one common terminal (c), one normally open terminal (no), and one normally closed terminal (nc). This is also called a “changeover” device because the common contact changes. Rated for either 18 v max with a 12 v dc coil rating or 36 v max with a 24 v dc coil rating. 1 a at 30 vdc relay contact rating. Broad offering of form a (spst), form 2a (spst with two terminals), and form c (spdt) relay options. 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. Allows remote control of relays. Provides eight form c relays.
