Electrical Connections
To use an MFC 1100 Series instrument with any equipment other than complimenting MKS
modules, consult the manufacturers' specifications for connection, and for proper electrical and
power characteristics. Refer to Appendix A, Product Specifications, beginning on page 39, for
electrical requirements of the 1100 Series instruments.
Type “D” Connector
Table 1 shows the pinout of the 1100 Series instruments that have a Type “D” connector (Types
1159, 2159, 1162, 2162).

Note
1.
The 0 to 5 VDC flow signal output comes from pin 2 and is
referenced to pin 12 (signal common).
2.
Any appropriate 0 to 5 VDC input signal of less than 20K ohm
source impedance referenced to pin 12 can be used to supply a set
point signal to pin 8.
3.
There is no internal connection on the pins assigned a “No
Connection” function.
