The Keyence IG-1500 Amplifier Unit is a panel-mount main unit designed to deliver precision measurement and versatile output control for advanced sensing applications. As part of the IG Series, this model is optimized for seamless integration into automated systems that require stable analog feedback and high-resolution digital monitoring.

One of the standout features of the IG-1500 is its dual 7-segment digital display, which provides real-time readings in a clear and intuitive format. The upper display offers a two-color (red/green) five-digit output, while the lower display presents a green five-digit reading. With a selectable resolution range from 1 µm to 1,000 µm, users can tailor the display precision to suit different measurement tasks, from fine adjustments to broader-scale monitoring. This flexibility ensures that operators receive the most relevant data for their specific application.

In terms of outputs, the IG-1500 is engineered for maximum versatility. It supports NPN/PNP open collector judgment outputs, with up to three channels available for reliable process control. In addition, it includes a dedicated edge check output with fast response times for dynamic applications. Its analog output capabilities stand out, offering multiple voltage and current formats (±5 V, 0–5 V, 1–5 V, or 4–20 mA) to meet the needs of a wide range of equipment and monitoring systems. With a display accuracy of ±0.05% of F.S. for voltage and ±0.25% of F.S. for current, along with excellent temperature stability, the IG-1500 ensures consistent measurement quality.

Efficiency is another core advantage of the IG-1500. The unit incorporates three power-saving modes—normal, half, and all—allowing users to optimize energy consumption without impacting measurement integrity. At its most efficient, the unit consumes only 2200 mW, making it a practical solution for energy-conscious facilities.

The IG-1500 is also built with durability in mind. With an IP-rated housing, resistance to vibration (10 to 55 Hz, double amplitude 1.5 mm), and shock resistance in all axes, it performs reliably even in challenging production environments. Constructed from polycarbonate and polyacetal, and equipped with accessories including a panel mounting bracket and front protection cover, the unit is engineered for long-term use and straightforward installation.

Operating within a temperature range of -10 to +50 °C and relative humidity of 35 to 85% RH, the IG-1500 is suitable for diverse industrial environments. At just 170 g (including supplied accessories), it offers compact yet robust performance, making it an excellent choice for panel-mounted precision measurement systems.

In summary, the Keyence IG-1500 provides high-resolution measurement, versatile output control, power efficiency, and durability, making it a reliable amplifier unit for advanced automation, inspection, and monitoring applications across industries.
