Keyence

Keyence LK-HA100 Head Expansion Unit, 1 analogue output, 10 heads max, 24 VDC

SKU CH-S27B-SQZCD MPN LK-HA100

Expands a Keyence LK-G5000 controller with up to 10 heads and provides one analogue output at 24 VDC

  • Connect up to 10 heads from a single controller
  • One analogue output provides ±10 V voltage or 4 to 20 mA current
  • Operates on 24 VDC supply with 0.6 A draw per head
  • Supports up to 12 heads at 3.5 A maximum consumption
  • Functions in 35 to 85 % RH environments without condensation

What this unit adds

The Keyence LK-HA100 is a head expansion unit that connects to an LK-G5000 series controller, allowing up to ten additional heads to be driven from a single controller. It is intended for engineers who need to extend measurement capacity on an existing Keyence system.

What to verify before ordering

Your controller must be an LK-G5000 series main unit that supports head expansion, and your 24 VDC supply must be able to deliver up to 3.5 A when all twelve heads are connected. The analogue output provides ±10 V at 100 Ω impedance and 4 to 20 mA into a maximum load of 350 Ω. Operating humidity must stay between 35 and 85 % RH with no condensation.

Thermals, noise and power draw

The unit draws 0.6 A with one head and up to 3.5 A with twelve heads from the controller’s 24 VDC rail, so power dissipation scales with the number of connected heads. No fan or active cooling is mentioned, implying silent operation in a cabinet environment. The module also supports Web, SNMP and Telnet protocols for remote monitoring.

Highlights

  • Connect up to 10 heads from a single controller
  • One analogue output provides ±10 V voltage or 4 to 20 mA current
  • Operates on 24 VDC supply with 0.6 A draw per head
  • Supports up to 12 heads at 3.5 A maximum consumption
  • Functions in 35 to 85 % RH environments without condensation

Questions about this item

Does the Keyence LK-HA100 come with sensor heads or cables, or must they be purchased separately?

The LK-HA100 is a head expansion unit only; sensor heads and connection cables are sold separately.

How many sensor heads can one LK-HA100 support, and does the current draw change with the count?

Up to 10 heads can be connected; current consumption is .6 A with 1 head and 3.5 A with 12 heads.

What does the ±10 V analogue output actually drive in a real setup?

The output delivers ±10 V at 100 Ω impedance and 4–20 mA into a maximum 350 Ω load.
