Pressure Clamp Connection Characteristics
The STB4S-00 uses pressure clamp terminals to maintain conductor contact through mechanical clamping force. Unlike conventional screw terminals, this connection method does not depend on a threaded terminal screw to secure the conductor.
Furthermore, the specified conductor range accommodates wiring with or without sleeves. However, technicians must observe the applicable conductor cross-section limits when preparing field wiring.
For Yokogawa digital I/O applications, verify the terminal block configuration against the selected module’s connection requirements before installation.
Frequently Asked Questions
Q: What conductor sizes does the Yokogawa STB4S-00 support?
A: Without sleeves, the specified range is 0.5 mm2 to 2.0 mm2 (AWG 20 to 14). With sleeves, the range is 0.5 mm2 to 1.5 mm2 (AWG 20 to 16).
Q: Which Yokogawa I/O modules are identified as compatible examples?
A: The supplied information identifies SDV144, SDV531, and SDV541 as compatible module examples. Confirm the terminal arrangement and configuration against the applicable module documentation.
Q: Does the STB4S-00 require an external power supply?
A: The STB4S-00 is a passive terminal block. It provides a physical wiring interface rather than an independently powered signal-processing function.
Field Installation Guidelines
- Verify module compatibility: Confirm that the selected Yokogawa digital I/O module supports the STB4S-00 terminal configuration.
- Isolate field circuits: De-energize applicable circuits before connecting or disconnecting conductors.
- Prepare conductors: Select wire sizes within the specified limits. For sleeved conductors, use 0.5 mm2 to 1.5 mm2.
- Insert conductors: Position each conductor correctly within its designated pressure clamp terminal.
- Inspect connections: Check conductor seating and mechanical retention before energizing the circuit.
- Separate signal wiring: Route field signal conductors appropriately to minimize exposure to electrical interference from power cables.
- Verify wiring: Compare terminal assignments against the applicable Yokogawa module wiring documentation before commissioning.
