7.2. Outputs
7.2.1. OUT_STATUS
The signal OUT_STATUS is a programmable digital output for the indication of the state of:
Ì An input
Ì An output
Ì A node on the logic diagram designed with the aid of EUCHNER Safety Designer.
7.2.2. OUT_TEST
The inputs and the cables can be monitored for short circuits or overload states using the OUT_TEST signals (Figure 9).
MSC-CB
E-STOP
INTERLOCK
¨ The maximum number of inputs that can be controlled by
each OUT_TEST output:
- 4 INPUTS (parallel connection) (MSC-CB, FI8FO2,
FI8, FM4, FI16)
¨ The maximum permissible length of the cable on the
OUT_TEST output is 100 m.
Figure 9: OUT_TEST
7.2.3. OSSD (MSC-CB, FI8FO2)
The OSSD outputs (Output Signal Switching Device) are short circuit proof, monitored for cross circuit and supply:
Ì In the ON state: U
V
- 0.75 V – U
V
(where U
V
= 24 V ± 20 %)
Ì In the OFF state: 0 – 2 V eff.
The maximum load of 400 mA at 24 V corresponds to a minimum ohmic load of 60 Ω.
The maximum capacitive load is 0.8 µF; the maximum inductive load is 30 mH.
