Keyence KV-N60AT Transistor Output PLC

Keyence KV-N60AT PLC: Higher I/O Count for Compact Machines

The KV-N60AT belongs to the Keyence KV Nano series of all-in-one terminal block PLCs. This base unit suits small to medium machines that need more points than 40-I/O models allow. It combines a 100–240 VAC supply with 36 input points and 24 MOSFET transistor outputs. Because transistor outputs switch faster than relay contacts, the KV-N60AT fits high-cycle packaging, sorting, and assembly equipment.

Technical Specifications of the KV-N60AT

The controller executes basic instructions in 50 ns and application instructions in 170 ns. Program capacity reaches 16k steps, which supports moderate ladder logic and KV Script routines. Three positioning pulse outputs run at 100 kHz maximum, enabling simple motion tasks without extra modules. Two high-speed counter channels accept 100 kHz single-phase or 50 kHz phase-difference signals for encoder-based measurement.

Output Ratings and Load Handling

Each transistor output is a sink (NPN) MOSFET rated at 30 VDC, 0.5 A per point. This design drives DC solenoids, pilot valves, and solid-state relays directly. Additionally, the sink configuration suits common-negative DC wiring found in many Asian machine panels. However, inductive loads require flyback diodes to protect the output stage. Therefore, users should confirm load current before wiring multiple devices to one point.

I/O Expansion and Communication

Users can attach up to eight expansion units to the KV-N60AT, raising total I/O to 256 points beyond the base unit. A built-in RS-232C modular connector supports KV STUDIO programming and no-protocol serial communication. For larger systems, backplane communication modules provide additional connectivity options.

Electrical and Mechanical Parameters

The KV-N60AT operates on 100 to 240 VAC with +10%/−15% tolerance. An auxiliary 24 VDC output delivers 0.6 A for sensors or small loads. Operating temperature ranges from 0 to +55 °C, while storage tolerance extends from −25 to +75 °C. Relative humidity must stay between 5 and 95% RH without condensation. Installation altitude must remain below 2000 m.

Installation Guide for the KV-N60AT

First, mount the base unit on a DIN rail or directly onto a panel using the provided mounting holes. Next, connect the AC power terminals to a suitable supply circuit. Then wire input devices to the 36 input terminals, observing the common configuration. After that, connect DC loads to the 24 transistor terminals while adding flyback diodes on inductive devices. Finally, link the RS-232C port to a PC for programming via KV STUDIO.
