For easier wiring of single GPI and/or GPO signals, this break-out box can
be used. 16 GPI signals and 12 of the 16 GPO signals of a GPIO card with
relayoutputs(A949.0436)arewiredtosingle,4-pin‘Combicon’terminals
(seebelow),providingtherelaycontactsoropto-couplerinputs,aswellas
GNDandashortcircuit-proof5VDCsupply.
If voltages exceeding 50 V (AC or DC) are switched, the break-out box must
be placed within a closed rack in order to avoid shock hazards by touching
the contacts.
  Fourofthe16GPOsignals(GPO1...4,marked in black on the front panel)
are connected to solid-state relays whose power terminals are wired to the
‘Combicon’ terminals.ThesepowercontactscanswitchACloadsfrom
24...240 V with a maximum total current of 5 A over all 4 relays.
For safety reasons, these four terminals have no additional GND and 5 V
supply. All remaining low-voltage terminals (GPI 1...16, GPO 5...16) are
coded on pin #4 in order to prevent high-voltage connectors being inserted
by mistake.
The high-voltage connectors must be coded, as shown below; six coding
elements (order no. C054.251100) are included with the break-out box.

  Eight4-pin‘Combicon’plugswithscrewterminals(C054.251104)are
includedwiththebreak-outbox. If more plugs arerequired, please order
separately.Ontherearoftheboxtwo37-pinD-typesockets(f)areprovided
for connection to the GPIO card. For matching cables please refer to the table
