Multi-Box I/O Module

The optional Model 493.43 Multi-Box I/O module allows multiple controllers to

share a master hardware synchronization clock and pass station interlock state

information between each other. In addition, this front panel module also

provides user station interlock inputs and outputs.

Module features • 4 optically isolated station interlock inputs (J8)

• 4 station interlock outputs with relay contacts (J9)

• Box In (J51) and Box Out (J52) to connect multiple MTS controller boxes to

share station interlock status and the master synchronization clock.

• 32 Mb FLASH disk on board

• Box address switch (software readable) allows you to set a unique address

for each controller in a multi-box chain.

J8 Interlock IN

Connector J8 Interlock IN provides four station interlock inputs that can be

connected to external interlock chains.

• Inputs 1 through 4 are dedicated as a station interlock.

• All inputs are optically isolated.
