Safety outputs (equal or reversed).
ATTENTION!
Auxiliary output is only to no safety functions.
5.5 TEST OUTPUTS
To monitor the digital inputs configured as contact, it is necessary to use the test outputs (TEST_A and TEST_B)
generated by the PSRW. The PSRW has two test output channels that must be connected to their respective
input channel (channel A to channel A/channel B to channel B) for the correct operation of the input.
The OUT TEST TEST_A and TEST_B signals must be used to monitor the presence of short-circuits or overloads
on the inputs see
.

ATTENTION!
The maximum allowed length for test outputs connections is 30 meters.
ATTENTION!
Is not allowed connect the
test outputs to supply an external component.
5.6 OSSD OUTPUTS
The OSSD are short circuit protected, cross circuit monitored and supply:
In the ON condition:
Uv - 1 V
(where Uv is 24 V ± 20 %).
In the OFF condition:
0 V / 2 V
rms
.
The maximum load of
2A@24V
corresponds to a minimum resistive load of
12 Ω
.
¹
Each OSSD channel can
supply up to two (2) Amps. However, the sum of the currents of the four channels cannot exceed 2 (two) Amps.
The maximum capacitive load is
1 uF
.
The maximum inductive load is
30 mH
.

Section 6.2 TECHNICAL SPECIFICATIONS on page 6-1
for maximum current.
