Description
The safety-related
F3 DIO 16/8 01
remote I/O is a compact system in a metal enclosure
with 16 digital inputs, 8 two-pole digital outputs and 2 pulsed outputs. The two-pole outputs
consist of 2 switches connected in series, one switching to L+ and the other switching to L-.
The remote I/O is available in a model variant for SILworX and a model variant for ELOP II
Factory. All variants are described in this manual.
The remote I/O serves to extend the I/O level of HIMax and HIMatrix controllers, and is
connected to them via safe
ethernet
. The remote I/O itself is not able to run a user program.
The HIMatrix remote I/Os are not multi-master capable.
The remote I/O is suitable for mounting in Ex-zone 2, see Chapter 4.1.5.
The device has been certified by the TÜV for safety-related applications up to SIL 3 (IEC
61508, IEC 61511 and IEC 62061), Cat. 4 (EN 954-1) and PL e (EN ISO 13849-1). Further
safety standards, application standards and test standards are specified in the certificate
available on the HIMA website.
3.1 Safety
Function
The remote I/O is equipped with safety-related digital inputs and outputs. The input values
on the inputs are safely transmitted to the connected controller via safe
ethernet
. The
outputs are safely assigned their values by the connected controller via safe
ethernet
.
3.1.1
Safety-Related Digital Inputs
The state (HIGH, LOW) of each input is signaled by an individual LED.
Mechanical contacts without own power supply or signal power source can be connected to
the inputs. Potential-free mechanical contacts without own power supply are fed via an
internal short-circuit-proof 24 V power source (LS+). Each of them supply a group of 4
mechanical contacts. Figure 1 shows how the connection is performed.
With signal voltage sources, the corresponding ground must be connected to the input (L-),
see Figure 1.
