Installation Guide
- Mount the GT2-E3P into a GT2-100N or GT2-100P unit.
- Use it as an expansion board for multi-channel setups.
- Wire the no-voltage input for timing, preset, reset, or bank control.
- Connect PNP output lines to your PLC or controller.
- Keep supply voltage within 10 to 30 VDC.
- Allow enough clearance for heat release.
- Check all connections before power-on.
Debugging and Maintenance Convenience
The GT2-E3P supports simple bank switching and preset functions. Technicians can adjust response time without extra tools. The digital display shows fine measurement changes. Maintenance is easy because the unit uses standard Keyence GT2 series accessories. Regular cleaning and connection checks keep it stable. No special calibration is needed for normal use.
Compatibility Notes
The GT2-E3P works with GT2-100N and GT2-100P amplifier units. It also supports optional GT2 series communication units sold separately. Use it with GT2-Pxxx heads for longer response time settings. The PNP output matches common industrial controllers. This module has no built-in communication port. Add a communication unit if network data is needed.
