7.13. CR- 0 MODULE (SLOTS 3 to 13…)
The CR-0 module (controlled by a dedicated Cortex controller) is an universal I/O module
with a power relay, equipped with:

2 x SR6-51 power relays → terminals 22, 24 ;

2 internal inputs for power relay control;

1+3+5 = 9 digital inputs with programmable
sensitivity threshold >20/>50 V DC
→ terminals 1÷5, 13÷15, 17 ;

4 make-contact relays (2 pairs) → terminals 7, 8, 10, 11;

1 switchable relay → terminal 20 .
All signals of CR-0/CM-0/PR-0/IO-0 modules are grouped into one 24-pin MSTBA2.5/24-G
strip (pitch: 5.00 mm, max 12 A, 250 V).
CAUTION:
The strips can have pins with screw or spring terminals as well as measurement pins for
probes. For 24-pin I/O modules, it is recommended to use pin stacks!
Fig. 7.13. Terminals of the CR-0 module.
CAUTION
Following a switching operation, a small electric charge Q of approx. 1.2 uC (microcoulombs) may persist on
terminals 22 – 23 and/or 24 – 23.
Touching these terminal pairs may result in an unpleasant shock pulse.
