Direct I/O MTB panel integration
1) Note the locations of pin number one (#1) of CN1 and CN2 .
Although the pin #1 locations are the same with respect to the connector
keying, the connectors are oriented differently.
2) The P1 jumper is used to set the operation of the “control on” Lamp.
In the 1--2 position (MTBD) the lamp is controlled by the I/O system (on
when 24V is applied to pin CN2--32). In the 2--3 position (MTBI) the
lamp is on whenever 24V is applied to the panel.
Input Interface Connector
Input signals from the direct I/O MTB panel are sent through input
connector CN 1 . These signals are available for use by the I/O system by
pins supplied with this panel. Table 9A.S shows the pin assignments and
functions for input interface ribbon cable on the push-button MTB panel.
