0 to 5 VDC or 0 to 10 VDC, and a current output of 4 to 20 mA. Sections 1 through 4 and 7 through 9 of this guide apply to both models 267 and 267MR. Section 5 refers to the model 267 only. Section 6 refers to the model 267MR only. -
Page 3: Electrical Installation
The 267MR has a field selectable 0-5 or 0-10 VDC output. (See section 6.0 for switch settings to determine whether the voltage output is set to 0-5 or 0-10 VDC). The 267 has either a 0-5 or 0-10 output, calibrated at the factory. - Page 4 1/2’’ conduit opening, PG9 or PG-13.5 electrical termination The model 267 and 267MR is a two-wire loop-powered 4 to 20mA current output unit (see diagram 5). The current flows into +EXC terminal and returns back to the power supply through the -EXC terminal (see diagram 6).
- Page 5 3.4 Current output units: 9 pin D-sub connector electrical termination The model 267 and 267MR is a two-wired loop-powered 4 to 20mA current output unit (see diagram 6). The current flows into +EXC. Pin 4 (+EXC) and return to the power supply through pin 9 (-EXC) (see diagram 7).
- Page 6 4.0 Calibration The 267 and 267MR transducer is factory calibrated and should require no field adjustment. Generally, the mounting position will have a zero shift effect on ranges below 1” WC. Whenever possible, any zero and/or span offsets should be corrected by software adjustment in the user’s control system.
- Page 7 (electronic manometer, digital pressure gauge, ect.) with at least comparable accuracy to the 267 or 267MR transducer (<±1% FS). With full range pressure applied to the high pressure port (reference port open to atmosphere), the span maybe adjusted by turning the SPAN adjustment screw.
- Page 8 5.0 Model 267 optional LCD display The model 267 is available with an optional 3 1/2 digit LCD display. The LCD display is adjusted at the factory prior to shipment. The LDC is connected to the zero and span adjustment potentiometers.
