64 Programming the VT1422A & VT1529A/B for Remote Strain Measurement Chapter 3
Spring and Screw
Terminal Modules
For mixed on-board SCP channels and RSCU operation, spring or screw
type terminal modules can be used. For standard SCP channel connections,
see Chapter 2 “Field Wiring” on page 35. For remote channels, connect the
individual wires from each VT1529A/B’s data interface cable to the
appropriate terminals for remote channel operation. The VT1539A SCP is
supplied with signal locator labels for each SCP position on a Spring
Terminal Module. No label is provided for the Screw terminal module.
Instead, Table 3-3 provides the relationship between each VT1539A signal
name and associated terminal name as printed on the Terminal Module.
Note: In the table below, color combinations may vary.
