24 Vdc Digital Input Module – 40 Channel (T8403)
There are input channel status LEDs on the module front panel, one for each field input. The input status LED mode is dependent upon the voltage level of the field I/O signal. Each field input voltage is measured and compared to six threshold levels (four configurable and two fixed) which produce seven threshold bands, as described in Section 8. Each threshold band can be defined to have a particular indicator mode: off, green, red, flashing green, or flashing red.
Each field input of the 40 channel 24Vdc digital input module. The input voltage is measured and compared to user-configurable threshold voltages to determine the reported field input state.
The module can detect open and short-circuit field cables when a line monitoring device is installed at the field switch. Line monitoring functions are independently configured for each input channel.
The module provides an onboard sequence of events (SOE) reporting with a resolution of 1ms. A change of state triggers an SOE entry. States are determined by voltage thresholds that can be configured on a per-channel basis.
