Channel-to-Channel Isolation and Analog Input Conditioning
The Commander 1900 series utilizes high-impedance input signal conditioning circuitry to process temperature, flow, and 4-20 mA loop variables. Channel-to-channel isolation prevents ground loop interference across active pens, maintaining signal integrity and pen position accuracy during full-scale step responses. Internal digital filters attenuate high-frequency process noise before translating loop values to servo-driven pen arm movements.
Frequently Asked Questions
Q: How should signal shielding be terminated for 4-20 mA analog input loops to prevent trace jitter?
A: Drain wires for shielded twisted-pair cables must be grounded at one single point (typically the instrument enclosure ground lug) to prevent common-mode noise interference across input channels.
Q: Can the pen calibration and chart rotation speed be adjusted directly on the unit?
A: Yes. The user-interface interface allows pen scaling adjustments, zero/span recalibration, and rotational speed selections without requiring external programming hardware.
Field Installation Guidelines
- Cut panel opening to specified dimensions (305 mm x 254 mm cutout clearance) and verify the panel thickness supports the 12 lbs module weight.
- Insert the unit through the front panel and tighten side-mounting brackets until the perimeter gasket forms a dust-tight seal.
- Wire the 115 VAC power input and process signal cables to the rear terminal blocks in accordance with local electrical code safety ratings.
- Ensure the instrument housing is bonded to protective earth (PE) using a dedicated grounding conductor prior to applying line power.
