Description
The X-DI 16 01 digital input module is intended for use in the programmable electronic
system (PES) HIMax.
The module can be inserted in any of the base plate slots with the exception of the slots
reserved for system bus modules. For more information, refer to the System Manual
(HI 801 001 E).
The module is used to evaluate up to 16 digital input signals. The digital inputs are current
sinking logic for 48 VAC to 120 VAC signals in accordance with IEC 61131-2 ( based on
type 1).
The module 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).
Refer to the HIMax Safety Manual (HI 801 003 E) for more information on the standards
used to test and certify the modules and the HIMax system.
3.1
Safety Function
The module evaluates the digital input signals and provides them to the user program.
The safety function is performed in accordance with SIL 3.
3.1.1
Reaction in the Event of a Fault
If a fault occurs, the module adopts the safe state and the assigned input variables transmit
the initial value to the user program.
The initial values must be set to 0 to ensure that the input variables transmit the value 0 to
the user program if a fault occurs.
The module activates the
Error
LED on the front plate.
3.2
Scope of Delivery
The module must be installed on a suitable connector board to be able to operate. If a FTA
is used, a system cable is required to connect the connector board to the FTA. Connector
boards, system cables and FTAs are not included within the scope of delivery.
The connector boards are described in Chapter 3.6, the system cables in Chapter 3.7, and
the FTA in chapter 3.8
