Keyence GT2-E3P PNP Expansion Unit Installation & Maintenance Guide
Product Introduction
The Keyence GT2-E3P expansion board serves the GT2 series high-accuracy digital contact sensor system. Specifically, this unit installs directly into GT2-100N or GT2-100P amplifiers. Furthermore, each board adds one measurement channel. Therefore, operators can build multi-point inspection stations with one display unit.
Core Value
Firstly, the GT2-E3P delivers PNP open collector outputs. In addition, it provides five control outputs: HH, HI, GO, LO, and LL. Moreover, the response time ranges from 3 ms to 1,000 ms. This flexibility suits both high-speed sorting and slow measurement tasks.
Furthermore, the GT2-E3P supports eco power-saving mode. Specifically, consumption drops to 4,000 mW in eco mode. Meanwhile, the standard mode consumes 4,200 mW maximum. Besides, the unit weighs only 80 grams. Consequently, panel space remains efficient.
Technical Insights
The GT2-E3P operates from 20 to 30 VDC power. Furthermore, the host GT2-100P supplies all power. Therefore, no separate supply wiring is needed. In addition, the board accepts no-voltage control inputs for timing and preset functions.
The output current rating reaches 50 mA maximum. However, this value drops to 20 mA when two or more sensor heads connect. Besides, the residual voltage stays below 1 V. Meanwhile, the 30-pin MIL connector handles all I/O signals.
Installation & Maintenance
Firstly, power down the GT2-100P amplifier before installation. Next, remove the expansion slot cover. Then, insert the GT2-E3P board into the slot. Furthermore, secure the board with the provided screws.
The GT2-100P accepts up to three GT2-E3P boards. Therefore, a single amplifier supports up to 11 channels. Besides, always verify power supply voltage after adding boards. Meanwhile, check all connector pins for proper seating.
For maintenance, inspect the board for dust accumulation. Furthermore, verify output signals with a multimeter. In addition, clean the connector contacts with isopropyl alcohol. Therefore, reliable operation continues over extended periods.
