8 2-channel Relay output module
8.1 Function
♦ The relay output module is laid out for two
output channels. Each output channel uses a
change-over relay for switching of potential-free contacts.
♦ Each relay output module has 4 LEDs, of which 2 are respectively
assigned to one relay. Each relay thus has two LEDs, one green and
one two-colour red/yellow LED. All LEDs are used for local signalling of
of the operating and switching status of the relays.
♦ As a rule the Relay module is controlled internal to the system (see
Signal-flow chart) by preceding Monitoring blocks (Monitor) or Logic
blocks)
♦ The LEDs of the relay output modules signal the status of the limits
monitored by the Monitor block. The type and manner of signalling is
determined by global and internal block parameters.
Note:
The signalling of the LEDs is described in section „Introduction“,
chapter 8.3.3.
