Interlock Terminal Rating And I/O Circuit - Panasonic LP-RF Series Setup & Maintenance Manual

4-4-3 Interlock terminal rating and I/O circuit

This section shows the following interlock terminals and I/O circuit loaded onto the I/O terminal block.
Interlock input terminals:
INTERLOCK 1(+) (X16)
INTERLOCK 1(-) (X17)
INTERLOCK 2(+) (X18)
INTERLOCK 2(-) (X19)
• INTERLOCK terminals (X16, X17 and X18, X19) are connected to the operating coil of the internal contactor in the
controller. Connect INTERLOCK (+) and INTERLOCK (-) with the non-voltage contact (dry contact) such as a relay or a
switch. Do not connect with the voltage contact such as a transistor.

• For the connection examples of the interlock terminals, refer to "4-5-4 Connection example of interlock terminals and
laser stop terminals" (P.103).
• INTERLOCK 1(+) (X16) and INTERLOCK 2(+) (X18) are connected to the interlock dedicated power supply +24DVC
internally. This power supply is independent from 24V OUT (X1, Y3) in I/O terminal.
