HIMA Z7306 Communication Module

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 safeethernet. The

outputs are safely assigned their values by the connected controller via safeethernet.

Safety-Related Digital Inputs

The remote I/O is equipped with 20 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.

The safety-related F3 DIO 8/8 01 remote I/O is a compact system in a metal enclosure with

8 digital inputs, 8 digital DO+ outputs (L- ground), 2 digital DO- outputs (S+ ground) and 2

pulsed outputs. The digital outputs DO4+, DO8+, DO4- and DO8- can also be connected as

two-pole connections.

The remote I/O is available in a model variant for SILworX and a model variant for ELOP II

Factory, see Chapter 3.2. 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 safeethernet. 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 4.1.4.

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.
