Yokogawa Process Control Connectivity

The TE16*B serves as the primary interface for input/output signal distribution, facilitating channel-to-channel isolation by providing discrete termination points for individual field loops. This passive terminal board ensures that field signals, ranging from analog instrumentation to digital relay states, maintain electrical integrity through robust M4 screw connections. When integrated into FIO (Field I/O) architectures, the unit utilizes standardized pin layouts to prevent wiring cross-talk. The design adheres to non-incendive requirements for Class I, Division 2 environments, ensuring that the termination layer does not contribute to ignition risks in process area cabinets.

 

 

 

Frequently Asked Questions

Q: Does the TE16B provide surge suppression for incoming field signals? A: No, the TE16B is a passive terminal block. It does not contain active surge suppression, filtering, or conditioning circuitry. External surge protection devices should be installed on the field side if transient voltage protection is required for sensitive instrumentation.

Q: Are there different electrical ratings for various TE16*B variants?

A: Yes, electrical specifications such as voltage (up to 250 V AC/DC or higher) and current ratings (10–16 A) vary by specific version. Always verify the marking on the physical unit against the project wiring diagram to confirm compatibility with the applied loop voltage and load current.

Field Installation Guidelines

  1. Mounting: Secure the block onto standard DIN-rails or cabinet chassis plates. Ensure all mounting screws are tightened to prevent mechanical shifting, which could lead to terminal wire fatigue or intermittent contact issues.
  2. Wiring: Use torque-calibrated drivers on the M4 screws. For multi-strand wires, utilize crimp-style ferrules to ensure uniform contact pressure across the conductor surface and prevent strand breakage.
  3. Grounding: Terminate cable shields according to the specific I/O module grounding scheme. Ensure a low-impedance path to the cabinet ground bus bar to maintain the electromagnetic compatibility of the instrument loops.
  4. Environment: Verify that the installation location is within the -40 deg C to +85 deg C temperature range. As the unit carries an IP20 rating, ensure the enclosure provides adequate protection against liquid ingress and excessive particulate accumulation.
