The Model 2150 is a LonWorks based product that has four isolated relay outputs and four isolated inputs. All inputs and outputs are communicated via Standard Network Variable Types (SNVT). The outputs are four Form C relays. Form C relays are single pole double throw with Normally Closed and Normally Open output contacts. Four red LEDs indicate the status of the output relays. The four isolated inputs are capable of detecting a wide range of low voltage AC or DC input. The inputs can be used with voltage output, dry contact, sinking (NPN), and sourcing (PNP) type devices. All inputs and outputs have transient voltage suppression. Four green LEDs indicate the presence of an input signal.
