Description

Product Description
The satety-related F1 DI 16 01 remote I0 is a compact system in a metal housing with
16 digital inputs and 4 pulsed outputs.
The remote VO is avallable in varlous model variants for SILworX and ELOP II Factory, see
Table 4.
Remote /Os are connected to individual HIMax or HIMatrix controllers via safeethernet. They
are used to extend the 1/0 level, but are not able to run any user program by themselves.
The remote Vo is suitable tor mounting in Ex- zone 2, see Chapter 4.1.4.
The device is TOV-certilied for salety-related applications up to SIL 3 (EC 61508, IEC 61511
and IEC 62061), Cat. 4 and PL e (EN ISO 13849-1) and SIL 4 (EN 50126, EN 50128 and
EN 50129).
Further safety standards, application standards and test standards are specified in the
certifcates available on the HIMA website.
Safety Function
The remote VO is equpped with safety-elated inputs. The input values on the inputs are safely
transmitted to the connected controller via safeethernet.
Safety -Related Digital Inputs
The remote VO is equipped with 16 digital inputs. The slate (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 intemnal
short-circuit-proof 24 V power source (LS+). Each 24 V power source supplies 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.

Reaction in the Event of a Fault
If the device detects a fault on a digital input, the user program processes a low level in
accordance with the de-energized to trip principle.
The device activates the FAULT LED.
In addition to the channel signal value, the user program must also consider the corresponding
error code.
The error code alows the user to configure additional fault reactions In the user program.
Line Control
Line control is used to detect short circuits or open-circuits and can be configured for the remote
I/O, e.g. on EMERGENCY STOP inputs complying with Cat. 4 and PL e in accordance with
EN IsO 13849-1.
To this end, connect the pulsed outputs TO 1..O 2 of the system to the digital inputs (DI) of
the same system as follows:
