All eight input channels are individually configurable for RTD, resistance,
thermocouple, millivolt, volt, or milliamp input types. Each input channel
provides wire-off input, over-range, and under-range detection and
indication, when enabled.
Hardware Features
The module fits into any single slot for I/O modules in a ControlLogix
modular system. The module has a unique generic profile which may be
configured using your RSLogix 5000 programming software.
The module utilizes one removable terminal block, that provides
connections for the eight input channels. There are two cold-junction
compensation (CJC) sensors that compensate for the cold junction at
ambient temperature rather than at freezing (0°C). There are eight current
sources for supplying the RTD or resistance sensors. The module is
configured through RSLogix 5000 software, defining RTD, resistance,
current or voltage input paths.
