Ether1616 i/o expansion kit for the Acorn CNC controller (#14850)

The Ether1616 is an input and output expansion board designed to be used with the Acorn CNC controller. Each Ether1616 board adds an additional 16 optically isolated inputs and 16 relay isolated outputs to the Acorn CNC system, up to three Ether1616 boards can be added to an Acorn system for a total of 56 inputs and 56 outputs. Three different input voltages can be used: 5 volts, 12 volts and 24 volt. Input voltages are mix and match capable and are selectable via bank of four of inputs at a time with the provided plug-in SIP (Single In-line Pack) resistors. The default input voltage is 24 VDC.

Both the Ether1616 and Relay 8 modules provide both Din Rail mounting holes and Standoff mounting holes to allow the DIY installer a wide variety of mounting possibilities, The provided dedicated power supply is sized properly to provide enough power to drive the 16 relays. There are indicator LED’s on Ether1616 Inputs and on the Relay 8 Modules that indicate the state of the Inputs and Outputs.

The Ether1616 as the name implies communicates with the Centroid CNC12 software via Ethernet connection to the CNC PC. Ether1616 documentation is here.

Kit includes:
1.) Ether1616 Board
2.) Qty 2 Relay 8 Modules
3.) Qty 2 Keyed Ribbon Cables
4.) 24 volt DC power supply
5.) Ethernet Switch
6.) Qty. 2 Shielded Ethernet cables
7.) Qty 4 220 Ohm SIP resistors for 5 volt input
8.) Qty. 4 1k Ohm SIP resistors for 12 volt input

E-Stop Button with 2 contact closures #14534

- Industrial quality reliable Emergency Stop Button with two switches.
- Two contact closures for two estop circuits
- Use just one contact closure or use both
- For use with the Acorn CNC control board.

Mill, Lathe or Router use. Quickly and accurately setup tool heights in the tool library with a push of a button. The CENTROID TT-4 automatic tool height offset touch probe is plug and play with all Centroid CNC controls. Eliminates gauge blocks, paper, and repeated measurements. Save time and increase accuracy. Fully integrated into the CNC control tool library menu, just select the tool and press auto measure to set the tool height automatically. Makes measuring all types of tools faster and more accurate. Find the longest insert in a multiple insert tool quickly. Once you start using the TT-4 you'll wonder why you waited to purchase this time saving tool. Measure just one tool or a whole group of tools at once. Can also be used in the middle of a job to measure a replacement tool. Integrated with an Automatic tool changer for batch tool measurement. The TT-4 is based on KP-3 touch probe technology and is a robust kinematic design and works with all spindles even ones that with non conductive bearings (ceramic) or tooling that doesn't conduct (diamond).
