Model
2150: Four Digital Input / Four Digital Output Network Node
Description
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. Additionally, the Model 2150 includes a flexible firmware layer
that includes two Temperature Alarm Blocks, two Percent Alarm Blocks, four
Hardware Input Blocks and four Hardware Output Blocks. The Firmware Blocks can
be used individually or tied together to accomplish more complex logic. For
example, a relay output can be tied to the Temperature Alarm Block to turn on a
warning light if a temperature set point is exceeded. For efficient use of input
power, the Model 2150 uses a switching power supply. It can operate from a wide
range of low voltage DC or AC.
