Single-Channel (Partially-Safe) Digital Inputs Din44 - Festo CAMC-G-S3 Manual

2 Product description of safety module CAMC-G-S3
2.4.3 Single-channel (partially-safe) digital inputs DIN44 ... DIN49 [X40]
Use
The digital inputs DIN44..DIN49 have one channel. They can be used to connect passive
switches and active sensors.
Use the single-channel inputs as diagnostic inputs, for control functions which only re­
quire a single-channel input or in a combination of multiple inputs in order to request
safety functions.
If active two-wire sensors are used without self-diagnostics:
If the active two-wire sensor is not actuated, then not all the required tests are carried out
by the safety module. For this reason, regular actuation is required for a function test. We
recommended actuating every 8 hours or once per shift, but at least once every 24 hours
(è A.1.4, Tab. A.10).
To request and deactivate safety functions, only the two-channel inputs DIN40 ... DIN43 or
suitable logical combinations of single-channel inputs may be used.
Function
