HIMA HIMax®Digital Input Module X-DI 16 01

Product 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.

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.

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.

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

Assembly

The input module has 16 safety-related digital inputs 48/120 VAC for contact makers. For

safely detecting a high level on the digital input, the voltage and current thresholds must be

exceeded, see Table 8.

The 8 short-circuit-proof supplies feed 2 supply outputs each (S1 to S8). One supply output

is assigned to each digital input.

The safety-related 1oo2 processor system for the I/O module controls and monitors the I/O

level. The data and states of the I/O module are made available to the processor modules

via the redundant system bus. The system bus has a redundant structure for reasons of

availability. Redundancy is only ensured if both system bus modules are inserted in the

base plates and configured in SILworX.
