GE provides 3 varients of RSTi-EP safe feed modules EP 1901: one safe input, EP 1902: two safe inputs
and EP 1922: two safe inputs, with delayed disconnection, which are intended for connecting safety-
related equipment. The RSTi-EP safe feed-input modules are controlled using contact-based safety
transducers and/or safety transducers with OSSD (Output Signal Switching Device) inputs. The safety
function consists of the safe disconnection of 24 V outputs, the safe state of which is
24 V switched
off
(current path for outputs and the OSSD output is switched off).
All input sensors are independently supplied via separate voltage paths and report the current
machine status to the control unit.
Each RSTi-EP safe feed-input module safely switches off all following modules that are supplied by
the output current path (until the next EP-7641 power module) and thus creates a safety segment. To
switch the 24 V OSSD voltage back on, either an automatic or a manual start can be selected.
•
Automatic start: the safe output current path is switched on immediately after resetting the
safety circuit(s).
•
Manual start: the output current path is only switched on again if the start button has been held
down for a preset length of time.
