Analog Input Connectors (A1
– A2 – A3 – A4)
Not available on DT90N
Analog inputs use 9 pin connectors which can be used either as voltage channel, current channel and RTD channel.
Other than input channels, this connector can serve as voltage output.
Although each connectors are compatible for three signals, there is a limitation of 2 sensors per connector. So users are
required to have wiring plan based on sensor numbers. This wiring will make impact on channel declaration when
programming on
