19. Zero-voltage switching outputs via operation lines
The chambers are equipped regularly (MKT) or optionally (MK) with four zero-voltage switching outputs
(DIN sockets (7) and (8) located in the lateral control panel).
The operation lines serve to switch any device connected to the zero-voltage relay output. They can be
programmed On/Off in Fixed value and program modes.
Connection for operation lines “Switching output 1” and “2” occurs via DIN socket (7), connection for oper-
ation lines “Switching output 3” and “4” via DIN socket (8) in the lateral control panel:
OUTPUT TRACK 1+2
24V/MAX.2,5A
OUTPUT TRACK 3+4
24V/MAX.2,5A

Maximum loading capacity of the switching contacts: 24V AC/DC – 2.5 A
DANGER
Electrical hazard.
Danger of death.
Damage to switching contacts and connection socket.
∅ Do NOT exceed the maximum switching load of 24V AC/DC – 2.5A.
∅ Do NOT connect any devices with a higher loading capacity.
