CIT 700/750 — data acquisition rather than gas sensing
CIT 700 and 750 are process indicators/loggers and should be specified by input-channel type, isolation, acquisition speed and communications rather than a pressure range of their own. Confirm whether the chosen display supports the installed transmitters’ 4–20 mA, voltage or Modbus channels and the expected timestamp/record retention. Alarm processing and log export are configuration-dependent. These devices are not pressure/gas sensors or independent hazardous-area-approved safety systems simply because they display process values.

Model-specific measurement and electrical figures, output options and their source limitations.
| Measured feature | Maker data | Practical engineering implications |
|---|---|---|
| Primary class | Programmable multichannel process display/logger and controller | Displays connected transmitter signals; does not itself sense gas or pressure. |
| Screen contrast | CIT 700 3.5-inch TFT in 96×96mm front; CIT 750 5.7-inch TFT in 144×144mm front | These are two physically different panel-cutout sizes. |
| Acquisition | Up to 60 logged channels, max 10 Hz sampling; additional calculated/IO channels up to 90 | A 90 logical-channel ability is not 90 analogue terminals on a base device. |
| Internal storage | 1.5 GB internal memory | Retention length depends on recording channel count and frequency. |
| Hardware expansion | Three configurable input/output slots and modular I/O selection | The exact analog current/RTD/pulse contacts depend on inserted modules. |
| Logic/control | 35 mathematical/logic functions and eight PID controllers with autotuning | A process PID is not automatically a certified fire/gas safety shutdown device. |
| Physical ports | RS485 Modbus RTU, RS232, USB host, Ethernet Modbus TCP by configuration | Connectivity options require installed interface modules/firmware. |
| Auxiliary field power | 24 V DC transducer power output | Calculate connected pressure transmitter load before relying on internal supply. |
| Ingress | IP65 front panel on appropriately sealed cut-out; rear housing/connectors IP20 | Do not call a panel-mounted whole device IP65 inside wet cabinet. |
| Environment | 0–50 °C standard with optional extended ambient version | Confirm actual SKU, panel venting and condensation management. |
System selection and verification
The same operator display family covers data acquisition and logic, but the CIT 700 and CIT 750 have materially different panel dimensions. The original BD|SENSORS product sheet lists up to 60 logged channels and 10Hz logging, whereas up to 90 I/O/logic channels are virtual/configuration architecture and not 90 built-in physical connections. In a pressure-monitoring panel, select actual input modules, overrange/fault and sensor excitation, then separate process control PID from independently approved protection functions. The front enclosure has IP65 only under the specified sealing arrangement; rear terminals are IP20.
