  • Page 11 By default, all MB2 inputs are 24V tolerance for industrial sensors and switches. However, sometimes we need to interface with 5V devices, such as MPG and low voltage sensors. On the topic “5V inputs for low voltage devices” shows the way to hack the MB2 board and a simple interface circuit. Switches Figure 7, Input terminals shows 22 input terminals.
  • Page 12 , (a) shows a PNP input connected to an external power source. This connection is Figure 9 totally isolated from any part of the MB2 circuit. This external circuit, for instance, could be the fault output of a VFD drive or servo drive.
  • Page 13 , (c) this connection gives an alternative for PNP sensors to connect to NPN inputs. Figure 10 However, the logic is inverse, so you must also change the logic in the corresponding setting within Mach to also be inverse. www.CNCRoom.com Page 13...

  • Page 15 Relays The MB2 comes with two on-board relays, K1 and K2. Both provide NO or NC contacts. MB2 v1.5 or later, also provides an “OFF Delay” feature. To activate this feature the user needs to follow the instructions as set out on on page 17, note *7 under the heading of Modifications.
  • Page 16 X203 - X210 and then sends out an OK signal to the next device. However, if there is an error feeding in, MB2 will send out a “Not OK” signal by de-energizing the OSSD output and the external safety circuit will cut power and stop the hazard.
  • Page 17 Modification Solder Bridges The MB2 has a number of places where the user can conduct modifications. Instead of using pin jumpers, solder bridges have been implemented to save cost and space. The user needs to solder or de-solder these bridges to achieve their purpose.

  • Page 49 Safety Circuit 3 Since the MB2 board supports an “Off-Delay” function for relay K1 and K2, it allows the user to create a timing sequence for devices that need to power up or power down independently at different times. In this circuit an AC line monitor for recognising a “Power-Out” or “Black-Out” condition has also been introduced.
