MOORE Industries' new family of universal, PC-programmable temperature transmitters and alarm trips offers 20-bit input resolution, long-term stability between calibrations, complete signal isolation, RFI/EMI protection, and metal housings that snap onto DIN-style rails.
The model CPA limit alarm trip and model CPT temperature transmitter and signal isolator/converter accept a direct signal input from a wide array of sensors and other analogue devices.
These include: 23 RTD types, nine thermocouple types, current and voltage signals, resistance and potentiometer devices, as well as direct millivolt sources.
The CPA provides one or two alarm relay outputs when a monitored process variable falls outside of user-set high and/or low limits. This is typically used to activate a warning light, annunciator, or shutdown system.
The CPT provides an isolated and linear current or voltage output (any range within 0-20mA or 0-10V) proportional to the input. The signal is ready for direct interface with readout instruments, recorders, PLC, DCS, or PC-based SCADA systems.
Upon failure, the CPT's analogue output can be user-set for upscale or downscale drive, fail to last value, or fail to selected value on input failure.
Combined alarm trip and transmitter options are available, reducing costs and installation time when both transmitter and alarm functions are needed at the same location.
