J43 Interlock
Connector J43 Interlock accommodates two general purpose inputs to be
connected to the interlock chain.
• Input 1 is dedicated as a station interlock.
• Input 2 is dedicated as a program interlock.
• Both inputs are optically isolated.
• If just one contact is used, the other must be jumped.
Cable specification
• 9-contact type D male EMI connector.
• Backshell–EMI metallized plastic.
• Cable–shielded twisted pairs (24 AWG minimum) with drain wire(s)
connected to the metallized backshell at the chassis.
Power characteristics
Channel inputs can be 3 volts (minimum) and 26 volts (maximum) from an
external voltage source.
Jumper plug
If connector J43 is not used, you must install a jumper plug to maintain the
integrity of the interlocks. Use jumper plug PN 100-007-948 or jumper pins 1
and 2; 3 and 4; 5 and 6; 7 and 8.
