DI1-DI4 Digital Inputs:
Optocoupler with internal 24 VDC power supply. Control with floating
contacts, with external voltage 12–24 VDC or with open collector
drivers PNP or NPN..
DO1-DO4 Digital Outputs:
Floating double-throw contacts, max. contact load rating 30 V/1 A
Relays must at all times be operated within the specified data range.
Inductive or capacitive loads are to be connected with suitable
protective measures (self-induction recuperation diodes for inductive
loads and series resistors for capacitive loads).
Design: 2x12-pin terminal strip for stranded or solid cable with a maximum section
2
of 1 mm (17 AWG). Observe the information on needed materials (see page 4-13).
"Standard Terminal Connections" section (see page 4-9) contains information on
standard terminal assignment. Please observe also the specifications in the
analyzer data sheet. Relays are shown in the unpowered state. The unpowered
state is the failure mode ("fail safe").
