Examples for applications
RS-NAGX5
Single-channel contact expansion for base
units with pnp safety solid state outputs
examples NAGU.1, NAGU.12, NAGU.1b
In case of protected wiring (short current circuit
exclusion) and regularly tests for example with
maintenance, up to category 4, PLe, SIL 3
reachable.
Single-channel contact
Input circuit A1 is to be connected with one of
the redundant safety outputs (13-14). Errors of
the expansion unit will be announced over the
feedback control loop (Y1-Y2) and the next
activation will be disabled.
In case of protected wiring (short current circuit
exclusion) and regularly tests, for example
during maintenance, up to category 4, PLe, SIL
3 reachable.
Dual-channel contact expansion
Input circuits A1 and A2 will be connected with
separately safety outputs (13-14, 23-24).
Errors of the expansion unit will be announced
over the feedback control loop (Y1-Y2) and the
next activation will be disabled.
In case of regularly tests, for example during
maintenance, up to category 4, PLe, SIL 3
reachable.
